KANTEI 3 – HAMON & BOSHI #1

Judging the hamon and the bôshi are the third step in kantei, the final step which allows one – in the ideal case – to identify the smith or at least the school. The hamon and bôshi are quite individual factors. Of course, this result of the Japanese approach in making blades that leaves a visible hardening pattern was initially purely functional but soon, the variations and activities that occur along this hardening pattern and which developed from technical improvements left scope for individuality. Again, as this series is on kantei, I want to leave out the metallurgical and technical aspect of the hamon and want to focus on what is visible. First of all, we distinguish between if the hardening is straight or undulating and refer thus to the two main types of a suguha (直刃) and a midareba (乱刃) respectively. According to the actual outline of the hamon, the latter type, i.e. the midareba, is further subdivided into a notareba (湾れ刃・のたれ刃, large waves), gunomeba (互の目刃, larger roundish elements), chôjiba (丁子刃, smaller clove/tassel-shaped elements), or tôranba (濤瀾刃, surging waves). Apart from that, there is the so-called hitatsura (皆焼) where large areas of the blade are hardened. A hitatsura can be based on a notareba, gunomeba, or even a chôjiba, so this term does not refer to a specific hamon outline. All these main and sub types are further differentiated and named according to their interpretation and these differentiations/names will be described later.

3.1 Nie and nioi

I would like to start with another, quite important factor that must be taken into account, and that is the question of hardening, or to be precise, the question of what crystalline effect is left visible due to the hardening. Here too, we distinguish between two main types, nie (沸) and nioi (匂), which are identical from a metallurgical point of view (both being of martensite) but differ in terms of visible effect. In other words, a swordsmith can harden a blade in a way that leaves larger, i.e. visible martensite crystals, nie, or in a way where the martensite crystals are so fine that no individual particles can be made out, nioi. Of course, there is also an intermediate condition which is referred to as ko-nie (小沸). And if the visible, that means the nie crystals are large and rough, we speak of ara-nie (荒沸) (see picture below), or if there are really obvious patches of large nie also the term kazunoko-nie (鯑沸・数の子沸, lit “herring roe nie”) exists but which is mostly reserved to describe the visible nie activities of Satsuma-shintô smiths. And irregular accumulations of nie are called mura-nie (叢沸) whereas ara-nie and mura-nie as well as in some cases also kazunoko-nie might not be intended by the smith and testify to poor craftsmanship. Incidentally, there is also the term hadaka-nie (裸沸, lit. “naked nie”) which describes single, isolated and mostly dark and somewhat larger nie, a feature that is usually associated with Suishinshi Masahide (水心子正秀). Back to nie and nioi in general. To distinguish between these two basic kinds of hardening, the terms nie-deki (沸出来) and nioi-deki (匂出来), or nie-hon-i (沸本位) and nioi-hon-i (匂本位), respectively have become standardized vocabulary. Please note that the term “ko-nie-deki” is not much in use at all.

ara-nie

Next I want to focus on the border of the hamon, i.e. the area where the hardened edge (yakiba, 焼刃) ends and the unhardened ji (地) begins. This border is called habuchi (刃縁) or nioiguchi (匂口) regardless of if the hardening is in nioi or in nie-deki. Well, to be precise, habuchi is the more neutral term for the border of the hardened edge whereas the term nioiguchi was born from the fact that there are always nioi at the border of a hamon, i.e. there is no such thing that the hamon goes over to the ji with nie only. Or in other words, there might be plenty of nie but they are always embedded into nioi along the habuchi, thus the term nioiguchi. With this we arrive at how to address the amount of nie/nioi and the condition of the nioiguchi. Plenty of nie are usually described as nie-atsushi (沸厚し) or nie-fukai/fukashi (沸深い・沸深し), although the former is more used to refer to the presence of ji-nie. Please note that the term nie-atsushi means literally “thick nie” but it refers just to the amount and not to the size of the nie crystals. And thick nioi, what automatically means a wide or deep nioiguchi, are referred to as nioi-fukai/nioi-fukashi (匂深い・匂深し). The opposite of a wide nioiguchi is a tight nioiguchi for which the term nioi-shimaru (匂い締まる) is used. Apart from that, the nioiguchi can be bright (akarui, 明るい) and clear (saeru, 冴える) or be dull/hazy or subdued (shizumu, 沈む) or look soft (yawarakai, 柔らかい) or weak (yowai, 弱い) respectively. The brightness of the habuchi or nioiguchi alone can be a good indicator for the school or smith, for example the early Osafune mainline smiths like Nagamitsu (長光) and Kagemitsu (景光) or the Kanbun-shintô smith Kotetsu (虎徹) are known for hardening a very bright nioiguchi. And the other way round, a subdued nioiguchi might either point towards a rural school or smiths who stuck to an early, classical workmanship, e.g. earlier Kyûshû and Hokkoku smiths. A noticeably wide nioiguchi speaks for shintô in general, or for Ôsaka-shintô and Hizen in particular. But again, characteristic approaches in how the nioiguchi is interpreted will be pointed out in the later chapters. Not to forget, don’t mix up the nioiguchi with the hadori polish! That means you have to look at the blade under a proper light condition so that the actual border of the yakiba shows itself and you not only look at the (cosmetic) course of where the hadori was applied.

In conclusion it must be said that apart from merely recognizing the nioiguchi to draw conclusions on a possible school or smith, there is also the point of view of technical and artistical skill and quality. That means, a bright and clear and first of all consistent nioiguchi is desirable and shows that the smith was adequately skilled. So if the nioiguchi varies considerably and “unnaturally” in width and/or brightness, it is a sign that the smith lacked skill and that you are not facing a work of one of the top masters. The same applies as indicated above to an irregular, unnatural presence of nie. In the following, I want to do it the same way as with the jigane/jihada, that means as we are on the topic of nioiguchi, I first introduce in alphabetical order all major hamon hataraki and conditions as most of them anyway focus along the habuchi, before going over to the different outlines/interpretations of the hamon.

 *

3.2 Hataraki and conditions of the hamon

abu no me (虻の目) – Lit. “horsefly eyes.” Closely arranged, roundish yakigashira seen along certain gunome-midare interpretations of the 2nd generation Hizen Tadahiro (忠広). The area resembles a pair of compound eyes, thus the name.

abunome

ashi () – A thin line of nioi that runs across the hamon towards the cutting edge. Ashi were first introduced to straight hamon patterns to limit the maximum size of a lateral crack of the yakiba to the distance between two ashi. In other words, a crack usually does not exceed an ashi because it is of a somewhat softer steel structure than the yakiba. According to the interpretation of ashi, a distinction is made between: nezumi-ashi (鼠足, lit. “rat’s legs”), very small ashi; ko-ashi (小足), small ashi; naga-ashi (長足), long ashi; chôji-ashi (丁子足), chōji-shaped ashi; gunome-ashi (互の目足), gunome or zigzag-shaped ashi; nie-ashi (沸足), ashi composed of nie; saka-ashi (逆足), ashi slanting upwards (i.e. towards the kissaki); and Kyô-saka-ashi (京逆足), ashi slanting downwards (i.e. towards the nakago).

ashi

fushi () – Lit. “bamboo node(s).” Pointed knot-like breaks in a straight hamon. Often seen on blades by Mino smiths.

fushi

ginsuji (銀筋) – Basicaly the same as kinsuji but slightly duller in color, thus the name ginsuji (silver line/string). However, the differentation of kinsuji and ginsuji is not clear but in old sword publications, ginsuji are often associated with Kagemitsu (景光).

hakikake (掃掛け) – Lit. “sweeping.” Similar to sunagashi, but much shorter and thinner and spilling into the ji. Can appear along the habuchi of a hamon and/or in a bōshi.

hotsure (ほつれ・解れ) – Arrangement of nie which make the habuchi look like a frayed piece of cloth. Also called nie-hotsure (沸ほつれ・沸解れ).

ika no atama (烏賊の頭) – Lit. “squid heads.” Wide and noticeably protruding elements, sometimes even up to the shinogi, along flamboyant and slanting hamon interpretations of the Fukuoka-Ishidō smiths Koretsugu (是次) and Moritsugu (定次) that remind of the head of a squid, thus the name.

ikanoatama

imozuru (芋蔓) – Lit. “potato vines.” Thick and conspicious inzuma appearing in the habuchi and hamon which are a very typical feature of Satsuma-shintō and Satsuma-shinshintō blades.

imozuru

inazuma (稲妻) – Lit. “lightning.” Crooked kinsuji which resembles a bolt of lightning.

inazuma

kani no te (蟹の手) – Lit. “crab hands.” Special gunome-midare inter-pretation with split yakigashira that protrude alternatingly to the left and right and which remind thus of crab claws. Please note that the term kani no te is used to refer to this feature when seen on Sue-Seki blades. In the case of Sue-Bizen works, the term kani no tsume (蟹の爪, lit. “crab claws”) has become established even if the same feature is described.

kaninote

kinsuji (金筋) – Lit. “gold line.” A short, straight, brilliant black line of nie that appears inside the hamon, usually near the habuchi. If crooked, the term nazuma (稲妻) is applied.

kinsuji

koshi () – The “hip” (koshi) of a hamon element. Raising part that follows the tani (谷), the “valley” of a hamon element, ending in the “head,” the yakigashira (焼頭).

koshitani

koshiba (腰刃) – A singular or a few high rising temper element(s) in the habaki area. A koshiba is sometimes also referred to as Mino-yakidashi (美濃焼出し).

koshiba

kuichigai-ba (喰違い刃) – Area of a hamon where the habuchi splits with the upper habuchi running over a noticeable distance more or less parallel and with a gap to the lower habuchi.

kuichigaiba

kuwagata-ba (鍬形刃)Hamon interpretation of for example the Yamashiro smith Nobukuni (信国) where two yakigashira protrude in a long manner to the left and to the right into the ji, remotely resembling the kuwagata crest on a samurai helmet.

kuwagata

kuzure (崩れ) – Crumbling, deformed part of a nie-based hamon, usually seen at a midareba. Also referred to as nie-kuzure (沸崩れ) or yaki-kuzure (焼き崩れ).

muneyaki (棟焼き) – Hardened areas along the back of a blade.

muneyaki

nie-sake (沸裂け) – Lit. “torn nie. ” Bright, black nie along a hamon which make the habuchi look like as if has been torn apart. This feature is similar to kuichigai-ba but shorter and more frayed.

nie-suji (沸筋) – Lines of nie running parallel to the hamon.

nijūba (二重刃) – Lit. “double ha.” A second habuchi line, consisting of nie or nioi, drawn parallel to the main habuchi.

nijuba

sanjūba (三重刃) – Lit. “triple ha.” A habuchi with two additional habuchi lines, consisting of nie or nioi, drawn parallel to the main habuchi.

sanjuba

sunagashi (砂流し) – Lit. “stream of sand” or “flowing sand.” Accumulation of nie that resembles the marks left behind by a broom speeping over sand. Sunagashi usually appear inside the hamon and near and parallel to the habuchi.

sunagashi

tobiyaki (飛焼き) – Lit. “flying hardening (elements).” Hardened spots in the ji which are not connected to the hamon.

tobiyaki

uchinoke (打除け) – A short nijūba directly over the habuchi that resembles a crescent moon. Usually seen on suguha-based hamon and/or blades forged in masame, e.g. on works of the Yamato Tegai school (手掻).

uchinoke

yakidashi (焼出し) – The beginning of a hamon around the ha-machi. At unshortened blades, the hamon usually runs a little bit into the tang. There are different interpretations of this starting of the hamon and we basically distinguish between the following forms: sugu-yakidashi (直刃焼出し), straight start which turns after a more or less short distance into the “actual” hamon; Ōsaka-yakidashi (大坂焼出し) (see picture below top), also starts straight or as gentle notare but the yakiba widens smoothly to turn into the “actual” hamon; Kyō-yakidashi (京焼出し) (see picture below bottom), the yakiba starts in suguha but turns then rather abruptly into the “actual” hamon; Mino-yakidashi (美濃焼出し), the yakiba starts with a koshi-ba (see koshi-ba); Satsuma-yakidashi (薩摩焼出し), term to refers to Satsuma-shintō blades where the hamon starts like at most kotō blades right away as midareba.

osaka-yakidashi

kyo-yakidashi

yakikomi (焼込み) – Prominent single hamon element right over the ha-machi or yokote.

yakikomi

yaki-otoshi (焼落し) – Lit. “fallen/dropped hardening.” Term to describe when a hamon does not start around the ha-machi but more or less noticeably later on the blade. It is often seen on very early blades and on blades that have been retempered.

yakiotoshi

() – Lit. “leaf.” Ashi that is separate from the habuchi and that appears scattered inside the hamon. In past-Muromachi times, also the term nioi-kuzure (匂い崩れ) was used to describe this effect.

From the life of a rural Edo period swordsmith

田舎鍛冶の生活

*

Whilst checking my archive for historic sword orders in another context, I came across an article published by Fukaminato Kyôko (深港恭子) – editorial member of the documentary archives section of the Reimeikan Kagoshima Prefectural Center for Historic Material – in Tôken Bijutsu No 543 (July 2001). This article contains very interesting information that I want to share with my readers as it gives a good insight into the life of a rural Edo period swordsmith, a facet of the Japanese sword that is still hardly addressed in relevant sources. The information Fukaminato forwards goes back to the collection of historic documents that was handed down within the local Nakamura family (中村), in particular the diary of the swordsmith Kiyotomo (清巴), but one after another.

The Nakamura family of swordsmiths is said to go back to the Muromachi-era Satsuma smith Kiyotomo (清友) who was active in the early decades of the 16th century and who had been a student of the Osafune-trained master Kiyosuke (清左). I want to skip the genealogy right after Kiyotomo and start in the early Edo period. Suffice it to say, the Nakamura smiths worked in a hereditary manner for the Kimotsuki family (肝付) who were retainers of the Shimazu clan and who were in control over Kiire (喜入) which was estimated with an annual income of 5,500 koku. Administrative center of the Kiire territory was the small town of the same name that is located about 15 miles (25 km) to the south of Kagoshima (and which was merged with expanding Kagoshima in 2004). See pictures below to get an idea of where the Nakamura family worked. They were actually not that far away from Kagoshima but as they were not employed by the Shimazu family, i.e. the Satsuma fief, and in view of the declining sword order situation at the time of Kiyoyasu (清保) and his son Kiyotomo (清巴), I address themhere as rural swordsmiths.

This family of swordsmiths might not be on everyone’s lips by the name Nakamura but it gave rise to the famous master Ippei Yasuyo (一平安代, 1680-1728) who was, as everybody knows, one of the winners of the sword forging contest held by shôgun Tokugawa Yoshimune (徳川吉宗, 1684-1751) in the sixth year of Kyôhô (享保, 1721). But our journey starts somewhat later, with the aforementioned Kiyotomo (清巴, 1784-1867), whose extant diaries cover (with a short interruption between the years 1796 and 1799) the time from Kansei seven (寛政, 1795) to Bunsei nine (文政, 1826). That means he started to write a diary at the age of eleven and stopped when he was 42 years old, or rather that is what is extant. He lived to the venerable age of 83, so we are facing about the first half of his life. Well, times had changed by then, of course also for swordsmiths, and the most famous child of the family, Ippei Yasuyo, had lived about a century ago. Incidentally, Yasuyo was the son of Yasusada (安貞) who was the son of Kiyosada (清貞). Kiyosada in turn was, if you start counting with Kiyotomo (清友), the 7th generation Nakamura main line. “Our” Kiyotomo (清巴) was the 13th head of the family (click here for a brief genealogy of the Nakamura family). The vast majority of the diary is about fulfilling certain official duties, annual events, temple or shrine visits, and reports on being sick and sword-related entries are actually rather rare. This is on the one hand only natural as these diaries were meant as, well, personal diaries, and not as minute business records but on the other hand, we find therein records on the production of farming tools like sickles and axes they made mostly on the basis of annual contracts and what neighboring towns he, his father, and his uncle went to deliver them. Actually, there are only two entries found in Kiyotomo’s diary that explicitly mention sword orders: One blade made for a private customer and a wakizashi that was ordered by his employer, the Kimotsuki family. However, we learn that Kiyotomo received from his employer in the tenth month of Bunsei one (1818) an order for 78 forked karimata arrowheards to be used in a yabusame event. The order said that 24 of them should come with an ornamental inome-sukashi and that those were paid 100 mon (文, copper coins) each. For the less elaborate arrowheads without an opening, Kiyotomo received 72 mon. So the whole order earned him about 6,300 mon, i.e. a little more than 1 ½ ryô. That’s about it when it comes to “samurai equipment” as all extant records, i.e. not only the diaries, and the utmost rarity of extant blades of Kiyotomo, his father Kiyoyasu, and his grandfather Kiyonari point towards the fact – and Fukaminato sees it that way too – that the Nakamura were merely making a living as smiths for agricultural and other tools by the start of the 19­th century. We learn from the diary that Kiyotomo bought the raw material iron from local sources like Kawanabe (川辺), Shinmaki (新牧), and Yukimaru (雪丸), all mining areas located in the mountain ranges to the west and south of Kiire. But from other Nakamura documents we know that at the glory days of the family, i.e. at the time Ippei Yasuyo’s uncle Kiyoyuki (清行) and grandfather Kiyosada (清貞) had been active, i.e. around Genroku (元禄, 1688-1704), and when sword orders were plenty, expensive and high-quality steels like Shisô Steel (宍粟鉄) from the upper reaches of the Chigusagawa (千草川) in Harima province and Izuha Steel (出羽鉄) from Iwami province were imported via a specialized Ôsaka-based trader named – nomen est omen – Tetsuya Gorôbei (鉄屋五郎兵衛).

 KiyotomoDiaries

Picture 5: Kiyotomo’s diaries.

 

Back to Kiyotomo. He writes in his diary that he became a page to the Kimotsuki when he was 16 years old and had to do service at their facilities on the ninth, 19th, and 29th day of each month. But he expressed the wish to end this duty and quit only two years later. Fukaminato assumes that his termination of the job might be connected to some health reasons as the diaries are full of reports of being ill but he must had been in the need for extra money because just three months after he had quit his page job, he started to work one evening a month as a clerk for the local Yamano family (山野). Before I finally introduce something indeed sword-related, I think it might also be interesting to let you know about the three major ceremonies or celebrations in the annual life of an Edo-period swordsmith that are also found in Kiyotomo’s diaries. The first was the so-called saiku-hajime (細工始め), the first craftwork of the New Year made on the second day of the first month. Blacksmiths make for example in a ceremonious manner a small sickle at that day and decorate with it the front pillar of the house or workshop. Next was the Kanayama-matsuri or fuigo-matsuri (金山祭・鞴祭), the Kanayama or Bellows Festival respectively, held each year on the eighth day of the eleventh month. And shortly later, on the 28th day of the eleventh month, the so-called kajiko (鍛冶講) ceremony was held where smiths presented offers to their protective deity Kanayamahiko (金山彦).

 

What about swords? As mentioned, extant works of Kiyotomo, Kiyoyasu, and Kiyonari are very rare. What we find in the Nakamura archive is an undated sword order from a certain Nomoto Suke’emon (野本助右衛門) that is addressed to a not further specified Nakamura Sei’emon (中村清右衛門, first name also reads Kiyo’emon). Well, Sei’emon was the hereditary first name of the Nakamura main line and thus born by several smiths, e.g. by the 6th gen. Kiyomitsu (清光), the 7th gen. Kiyosada (清貞), the 9th gen. Kiyofusa (清房), the 10th gen. Kiyomasa (清方), and the 12th gen. Kiyoyasu (清保), and also not much is known about the orderer Nomoto Suke’emon. So Fukaminato leaves this question to which Nakamura generation this order is addressed open but the order that I will introduce in the following shows the name Shirao Kinzaemon (白尾金左衛門). I did some research on this person and found out that his name appears on a list of retainers that followed in death lord Shimazu Mitsuhisa (島津光久, 1616-1694), the second Satsuma daimyô, by committing junshi (殉死). As the sword order states “like at the sword made for Shirao Kinzaemon,” I think we can narrow down Nomoto’s order to the time of the 7th gen. Kiyosada (清貞) and let me explain why. Kiyomasa was not yet born when Shirao committed junshi and his predecessor Kiyofusa was only 27 years old. Kiyofusa’s father Kiyoyuki would come theoretically into question but he did not bear the first name Sei’emon and when we assume that Shirao did not order his sword from a very young Kiyofusa, we arrive at Kiyosada who was a contemporary of Shimazu Mitsuhisa. So even if the records just mention “Nakamura Sei’emon” in this respect, I will take for granted for the time being that Kiyosada received this very order but will just refer to “the smith” in the following.

Nomoto Suke’emon
20th day of the twelfth month
to Mr. Nakamura Sei’emon

Very interesting is also the correspondence after the order was placed. Just eight days later, the letter is dated with the 28th day of the twelfth month, Nomoto inquires about his order as he has heard from a certain Iwanaga (岩長) that his blade turned out to have a not further specified kizu and how this might have an effect on the delivery. Reason for that is not Nomoto panicking but we learn from other letters that it is him who has to make arrangements with the polisher and all the other artists involved making a koshirae and that all this has to be done in a certain time frame as he wants to have his sword finished at the latest by the seventh month of the coming year when he has to proceed to Edo. He informs the smith about that in a letter dated with the twelfth day of the first month. So we learn that it was not necessarily the smith who did all this arrangements necessary to deliver a completed sword to the client. It is possible that this was the case at forges operating in the larger castle towns with an arranged infrastructure between all the craftsmen themselves (see pictures below), or more likely, there were agents doing all this for the clients. But from the fact that Nomoto makes kind of pressure right at the beginning of his sword being made, we can assume that seven months was just enough time to make arrangements with the togi-shi, habaki-shi, saya-shi, tsukamaki-shi, and so on, that means coordinating the entire process on the basis of the time each craftsman estimates for doing his job, taking into account his order situation and so on. Well, it would be interesting to know how it happened that Nomoto was informed about that kizu and that just about a week after the order was placed. Maybe the smith, i.e. Kiyosada, was handling this order with priority and started to work on the blade the very same day he received the order. Or he and Nomoto had been in touch before and Kiyosada had things prepared, e.g. already did some foundation forging, and just waited for the “official” order to come in to forge out from there the sunobe and so on. Because when we deduct the time for mailing, i.e. one day for the letter from Nomoto to the smith and one day for the letter or the personal talk of Iwamoto to Nomoto, six days sound pretty short for forging a blade. From another case found in the Nakamura archive we learn that such kizu must had been quite common. There is an undated letter extant where the blade was returned to the smith after the polisher had discovered a kizu, that means it the flaw was not visible with the foundation polish done by the smith himself. This letter too is undated and just addressed to Nakamura Sei’emon but the name Shirao Shirôbei (白尾四郎兵衛) appears on it and after some research I found in a Shimazu-related document a Shirao Shirôbei Kuniyoshi (白尾四郎兵衛国芳) in an entry from the fourth year of Enkyô (延享, 1747), mentioning him as yari fighting instructor. So if this is our man, then probably the 10th Nakamura generation Kiyomasa (清方, 1698-1782) was the smith. Also a wakizashi ordered by their employers, the Kimotsuki, to be granted to an unnamed young “man” at a genpuku ceremony had to be returned from the polisher as a kizu was revealed. This is mentioned in a document from Hôreki three (宝暦, 1753) and so here too Kiyomasa is meant. But Kiyomasa was not a nobody. He even studied in Kyôto with Iga no Kami Kinmichi (伊賀守金道) and received the honorary title Ise no Kami (伊勢守).

ShokuninB

Picture 8: saya-shi

This makes me think that even for a (rural but) renowned master like Kiyomasa, turning out a flawless blade was not taken for granted, also taking into account that he surely put extra effort into a blade made according to an official order from his employer. It was just a more or less common thing in this “league” and no whatsoever “harsh words” from any of the clients are found in these documents. Surely, we are not talking about the greatest masters of their time where customers paid a fortune to get one of their blades, and bearing in mind the humble order situation for a mid to later Edo period rural swordsmith, I think we should duly respect their work even if their blades might not be able to keep up with the high expectations we place today in art swords. So although rural, the Nakamura smiths were still held in high regard by local samurai as Nomoto writes in another letter that he places his order with Kiyosada (a blade of him can be found here) because really badly forged, “amateurish” blades are made in and around Kagoshima whose cutting edges are chipping even when cutting soft targets. Further he writes that this sword should accompany him for the rest of his life, so no wonder when he was much concerned about everything, also having in mind the humble salary of a simple hanshi (藩士) that I addressed in an article I wrote a while ago (download here)…

I hope I was able to provide with this article an interesting insight into the life of a rural Edo period swordsmith and another one is in work that has a historic sword order as a basis.

KANTEI 2 – JIGANE & JIHADA #3

2.3 Utsuri

 

I have forwarded some thoughts on utsuri here and I want to avoid going too much into metallurgical details with this kantei series. Well, utsuri means “reflection” and refers to a misty and more or less visible reflection in the ji (and sometimes also higher in the shinogi-ji) which is thought to be a hardening effect. The reflection can “shadow” (kage) the hamon, thus also terms like ha-kage (刃景), ha no kage (刃の景), or kage-hamon (景刃文) were in use in earlier times. The dark area between this reflection and the hamon below is called antai (暗帯) and according to the pattern of its appearance, we distuinguish between several different forms of utsuri which allow conclusions on the school (or sometimes even on the smith). Utsuri can be prominent, utsuri ga azayaka ni tatsu (映りが鮮やかに立つ) or utsuri ga senmei ni tatsu (映りが鮮明に立つ), or faint, awai utsuri ga tatsu (淡い映りが立つ) or asaku utsuri ga tatsu (浅く映りが立つ). That means the term tatsu (立つ) means in this context merely that utsuri “is present” and not that it “stands out” as in hada ga tatsu (i.e. “standing-out hada”).

Utsuri is very much a feature of the Bizen tradition and the Facts and Fundamentals of Japanese Swords makes a good point by saying “when you see utsuri there is a 70 percent chance it is a Koto-Bizen work.” Please note that when it comes to utsuri, the term used is an umbrella term that refers to a “whatsoever reflection” on the ji. That means not everything called utsuri is technically and metallurgically the same. In other words, the midare or bô-utsuri seen on Bizen, and the dan-utsuri seen on Aoe blades are quasi “real utsuri” and technically different from appearances like jifu-utsuri, shirake-utsuri, and tsukare-utsuri (疲れ映り) which are addressed as utsuri too due to their reflection-like appearance. Anyway, to see utsuri, a blade has to be in a good polish and you have to examine it under a proper light source. So when you lift up the sword and it is time to check the jigane, focus on the area where the hamon starts and let your eyes wander upwards whilst slowly changing the ange of the blade. Others suggest to hold the blade with the outstretched right arm behind the light source and with the tip facing left and the cutting edge down. But this only works when you have space of course and not at a kantei session where people are handling blades next to each other at a rather close distance. In the following I want to describe in alphabetical order the most common utsuri forms.

bô-utsuri (棒映り) or sugu-utsuri (直映り): A straight utsuri that appears first on hira-zukuri Bizen blades from the end of the Kamakura period (and on shinogi-zukuri Bizen blades somewhat later, towards the end of the Nanbokuchô period). We associate the early bô-utsuri on tantô very much with the Osafune main line and masters like Kagemitsu (景光) and Kanemitsu (兼光) and their direct students whilst the somewhat later bô-utsuri on tachi (or katana) was mostly applied by Ôei-Bizen (応永備前) smiths (e.g. Morimitsu [盛光], Yasumitsu [康光], Moromitsu [師光]) and the smith from the Kozori (小反) group.

 utsuri-bo

botan-utsuri (牡丹映り): Isolated roundish utsuri patches that follow in shape the underlying mokume or itame forging structures. This feature is associated with Osafune Kanemitsu and his direct students like Tomomitsu (倫光) and it is said that botan-utsuri is actually an appearance that occurs when certain areas are polished too much.

utsuri-botan

chôji-utsuri (丁子映り): Basically a midare-utsuri that shadows a chôji hamon. This term, which is actually a subgenus of midare-utsuri, is not that much in use as it is anyay hard to tell if a flamboyant midare-utsuri seen for example on a Fukuoka-Ichimonji blade is still midare or already chôji.

dan-utsuri (段映り): This term is used when more than one utsuri reflection is seen on a blade, for example a and a midare-utsuri, and this feature is usually seen on Aoe blades.

utsuri-dan

utsuri-dan1

herakage (箆景・ヘラ影) or herakage-utsuri (ヘラ影映り): This term is used to refer to a peculiar utsuri seen on Ko-Niô blades, e.g. by the earlier generations Kiyotsuna (清綱). It appears as about 1 cm long shirake patches that look like spatula (hera) traces, thus the name. The term was introduced by the Hon’ami family which referred in their publications to this kind of reflection as “Niô no herakage.”

jifu-utsuri (地斑映り): – If jifu spots appear all over the blade and form kind of a pattern, the term jifu-utsuri is used, following the aforementioned definition of utsuri as a reflection on the ji. Jifu-utsuri is a rare feature and hardly seen on any blades made later than the Nanbokuchō period. It is for example typical for Ko-Bizen (古備前), Un group (雲), and Aoe (青江) works.

midare-utsuri (乱れ映り): Midare-based utsuri that predates by far bô-utsuri. That means, smiths first produces midare-utsuri and that for quite a while until the Osafune main line smiths changed certain approaches in workmanship and produced towards the end of the Kamakura period a straight bô-utsuri. Please note that a midare-utsuri can also appear on a blade in suguha, that means it is not necessarily a “strict reflection” of the hamon. The Bizen smiths continued to produce midare-utsuri until the mid-Muromachi period but with the then shift towards mass production, it becomes pretty rare whilst it appears at the same time at other schools, like Sue-Seki (末関) and Bungo Takada (豊後高田). With the transition to the shintô era, utsuri again appears on works of smiths that revide the classical Bizen-Ichimonji style, i.e. at the Ishidô school (石堂) in particular and smiths like Tatara Nagayuki (多々良長幸), Tsunemitsu (常光), Tameyasu (為康), Heki Mitsuhira (日置光平), Korekazu (是一), and the Fukuoka-Ishidô smiths Koretsugu (是次) and Moritsugu (守次). But also the early shintô era successors of the Osafune Sukesada (祐定) lineage were able to produce again utsuri. In shinshintô times, midare-utsuri is of course seen at smiths who worked in Bizen style, e.g. Taikei Naotane (大慶直胤), Koyama Munetsugu (固山宗次), Tairyûsai Sôkan (泰龍斎宗寛), and Chôunsai Tsunatoshi (長運斎綱俊).

utsuri-midare

utsuri-midare1

utsuri-midare2

nie-utsuri (沸映り): When ji-nie forms a concrete pattern, we speak of nie-utsuri. Nie-utsuri only appears on blades in nie-deki or ko-nie-deki and is a typical feature of the Rai school (来). But also great Keichô-shintô and early shintô masters like Horikawa Kunihiro (堀川国広) and Dewa no Daijô Kunimichi (出羽大掾国路) were able to reproduce nie-utsuri. And it is even seen on some blades of Taikei Naotane (大慶直胤).

 

shirake-utsuri (白け映り・白気映り): In the case whitish shirake areas form utsuri-like patterns, we speak of shirake-utsuri. This feature is associated with swords from Mino but also from Kaga province and other more rural schools like Kongôbyôe (金剛兵衛) and Tsukushi Ryôkai (筑紫了戒) but sometimes it is hard to say if it is just shirake or already a shirake-utsuri. So you might find blades of smiths and schools that are known for shirake being described as showing a shirake-utsuri, for example the Enju (延寿), Naminohira (波平), and Mihara (三原) schools.

 utsuri-shirake

tsukare-utsuri (疲れ映り): This is again one of those utsuri that is not really an utsuri in the sense of a midare and bô-utsuri. It describes tired (tsukare) areas in the steel that can appear in a reflection-like manner, mostly after nugui is applied with a new polish.

KANTEI 2 – JIGANE & JIHADA #2

2.2 Jihada

 

After introducing the major points regarding jigane, we come to the different forms of jihada, i.e. visible forging structures.

itame-hada (板目肌): Itame is by far the most common forging structure seen on Japanese swords. There is the traditional approach to merely associate itame-hada with the Sôshû tradition but I think this rigid system of thinking, i.e. Sôshû equals itame and Bizen equals mokume should be taken with a grain of salt. That means from my experience as a translator, and I think I have translated blade descriptions way in the four digits over the last decade, the vast majority of kitae descriptions either start with “itame mixed with…” or “ko-itame mixed with…” This is just about itame/mokume as the traditional associations with masame, nashiji and so on are still very much valid. My tip: It is itame unless you really see some obvious burls, i.e. mokume. If it is a few burls here and there, it is probably itame mixed with mokume and I would only say “this blade has a mokume-hada” if the entire jihada or most of it consists more or less uniformly of mokume burls. As mentioned in the last chapter, we distinguish between ko-itame and ô-itame. The former, i.e. ko-itame, is quasi the “default hada” of the shintô era as there was a significant trend towards refinement throughout the early Edo period (culminating in the Ôsaka-shintô style for example). But it is also common for higher-quality Sue-Bizen blades (i.e. chûmon-uchi) where it might be even so tight that it looks like muji at a glance. A good way to identify a shintô is to check if there is masame in the shinogi-ji (see bottom picture below). So if this is the case, it is safe to concentrate on shintô. But please bear in mind that itame along the hira-ji and masame in the shinogi-ji is also a typical feature of Sue-Seki blades so you might check first if something speaks for Sue-Seki (i.e. sugata with sakizori, togari or fushi elements, shirake) before taking the shintô road on the basis of the masame in the shinogi-ji. Incidentally, it is said that the shintô masame in the shinogi-ji actually goes back to Sue-Seki as the majority of early shintô smiths had Mino roots. That means at the end of the kotô era, Bizen was literally wiped off the map as largest sword production site by the devastating flood of the Yoshii river and this left Mino, and Seki in particular, as leading manufacturer of blades. In short, the early shintô smiths who were hired from there by the newly established domains just continued to work on the basis of their scholastic Mino background. Their successors adjusted to the trend to refinement but by keeping basic elements like masame in the shinogi-ji. And that is why this Sue-Seki element “survived” in shintô times. An ô-itame is typically seen on early Sôshû blades, e.g. Masamune (正宗), Sadamune (貞宗), Hiromitsu (広光), Akihiro (秋広), but also on Ko-Hôki-mono (Yasutsuna [安綱], Sanemori [真守). Well, as there are burls seen on Ko-Hôki blades, they are also described the other way round, i.e. as showing ô-mokume but mixed with ô-itame. Anyay, a hada mix is almost always the case when it comes to kotô and as indicated in my tip above, you just name the dominating hada if you want to nail it down to a single forging structure.

itame1

masame-shinogi-ji

itame-nagare (板目流れ): An itame mixed with flowing or running nagare (流れ) structures is, when it comes to earlier kotô, a typical feature of schools that operated far from the then centers, for example the northern Hôju (宝寿) school or the southern Kyûshû schools and smiths like Jitsu’a (実阿), Miike (三池), Enju (延寿), and Naminohira (波平).

itame-nagare

itame mixed with masame (板目に柾目まじり): Well, some kind of nagare is seen at many schools and if the running structures tend to appear in a more linear manner, we usually speak no longer of nagare but of “mixed with masame.” So the above mentioned northern and southern schools are typical for a conspicuous itame-nagare that is the dominating forging structure of the entire blade. A mixed-in masame in turn is typical for all Yamato and Yamato-related schools (e.h. Mihara [三原] and Niô [二王]), but also for early Mino-mono (Kaneuji [兼氏], Kinjû [金重], Kaneyuki [金行]) and the Yamashiro Hasebe (長谷部) school where the masame appears towards the mune and towards the ha. At Sue-Seki schools that are not classically inspired and densely forged, the nagare towards the mune often appears as masame and this feature goes back to the same approach in forging as the aforementioned masame in the shinogi-ji. So what is nagare-masame towards the mune at a hira-zukuri blade is masame in the shinogi-ji at a shinogi-zukuri blade, to put it in a nutshell.

itame-masame

mokume-hada (木目肌): As mentioned above, mokume is when you see true burls. They might appear as larger ô-mokume or as smaller ko-mokume burls. An obvious ô-mokume can be seen for example at Ôei-Bizen blades (e.g. Morimitsu [盛光], Yasumitsu [康光], Moromitsu [師光]) but there is some kind of confusion when it comes to associate mokume in general and ko-mokume in particular as the Hon’ami school of thought seems to apply these terms to what others refer to as itame or ko-itame respectively. (Accordingly, most of the blades show for them variations of mokume instead of itame.) Again, I for my part say for the time being that a hada is itame unless there are some obvious burls and then it might be itame mixed with mokume. So please don’t get too much confused about when it is itame and when it is mokume as it is in many cases a mix anyway. (See bottom picture below which shows an itame mixed with mokume and nagare-masame.) By the way, conspicuous burls themselves are – depending on how you see them – referred to as uzumaki (渦巻, “whirlpools”) or nenrin (年輪) or jorin (如輪), the latter two terms both meaning “annual tree rings.”

mokume4

hada-mix

masame-hada (柾目肌): A masame-hada is usually associated with the Yamato tradition and indeed blades by the initial Yamato schools and those made by their offshoots and later smiths who worked in Yamato style indeed show in most of the cases some kind of masame. The most obvious masame is found on Hoshô (保昌) blades and on blades by the shintô Sendai Kunikane (仙台国包) lineage. But many other smiths worked in masame, for example the Mito smiths Norichika (徳鄰) and Norikatsu (徳勝), Sa Yukihide (左行秀), Dewa no Daijô Kunimichi (出羽大掾国路), Etchû no Kami Masatoshi (越中守正俊), Tsuguhira (継平), Kashû Kanewaka (加州兼若), and Ogasawara Nagamune (小笠原長旨), just to name a few.

masame

matsukawa-hada (松皮肌): A matsukawa-hada is either an ô-itame or ô-mokume that comes with thick chikei along the layers of the forging structures and that appears as large burls which remind of the bark (kawa) of a pine tree (matsu), thus the name. Such a forging structure is mostly seen on blades of Norishige (則重) and locally related smiths, e.g. Ko-Uda (古宇多) and Kashû Sanekage (加州真景) and later on blades by smiths who tried to emulate Norishige, e.g. Nakayama Shigehiro (中山重弘) and Mito Noritoshi (則利). Also Hankei (繁慶) tried to emulate Norishige although in his particular case we no longer speak of matsukawa but of hijiki-hada (鹿尾菜肌・羊栖菜肌) as his aproach reminds more of the brown edible sea algae of the same name.

matsukawa

yakumo-hada (八雲肌): A very peculiar jihada that is created by a combination of steels with different carbon content, an approach that results in thick and standing-out chikei-like structures. This kind of hada is mostly seen on blades by Mito Rekkô (烈公) and is not very common.

yakumo1

Shitahara-hada (下原肌): A Shitahara-hada shows conspicious uzumaki burls along the center of the blade, i.e. along the shinogi-ji or the center of the ji if in hira-zukuri. But these burls might also appear more towards the ha or in an irregular manner, that means as isolated large burls in places. As the kotô-era Shitahara school followed an approach in forging that resulted in such about centrally aligned burls, the term Shitahara-hada was coined to refer to their most characteristic feature.

shitahara1

shitahara

ayasugi-hada (綾杉肌): An ayasugi-hada appears as large regular waves and as such a forging structure was the trademark of the Gassan school, it is also referred to as Gassan-hada (月山肌). It was later revived by the shinshintô and gendaitô era Gassan smiths. But an ayasugi-hada or tendencies to ayasugi can also be seen at the Hôju (宝寿), Môgusa (舞草), and Naminohira schools and other early Kyûshû smiths like Gunshô (軍勝), Sairen (西蓮), and Jitsu’a (実阿), or at very early Yamato blades (but also at later Shikkake [尻懸] smiths) and at Momokawa Nagayoshi (桃川長吉).

ayasugi

nashiji-hada (梨子地肌): A nashiji-hada is essentially a very fine and dense ko-mokume that is harmoniously covered with ji-nie all over. A “true” nashiji-hada is mostly seen at earlier Yamashiro schools like Sanjô (三条) and Awataguchi (粟田口) but sometimes the very finely forged jihada of certain Ôsaka-shintô masters like Tsuda Sukehiro (津田助広), Ozaki Suketaka (津田助広), Ikkanshi Tadatsuna (一竿子忠綱), and Shinkai (真改) is also referred to as nashiji or tending to nashiji, mostly when it is an edge case between super fine and uniform ko-itame and muji.

nashiji

konuka-hada (粉糠肌・小糠肌): It is assumed that konuka-hada is a result of the Hizen smiths trying to emulate the nashiji-hada of the great Yamashiro masterpieces. As their approach turned out to bring forth quite a peculiar result, the terms konuka-hada or Hizen-hada (肥前肌) were coined to refer to these works. That means you should avoid using the term konuka-hada in any other context than Hizen as this just might cause confusion. Incidentally, this kind of hada reminds of rice bran (konuka), thus the name. Konuka-hada is hard to capture on pictures but you might be able to grasp the fineness and first of all the uniformity of the jigane of the 1st gen. Hizen Tadayoshi’s (忠吉) sunnobi-tantô that is shown below (which is by the way one of my most favourite blades, not mine though).

konuka

konuka1

chirimen-hada (縮緬肌): Like at nashiji and konuka, we are facing with chirimen-hada the attempt to introduce school-specific differentiations of what is basically a very fine and uniform ko-mokume that is harmoniously covered with ji-nie all over. That means, nashiji, konuka, and chirimen-hada have basically the same technical background but they are not the same appearances (with just different names). A chirimen-hada is now the “result” that is seen on Aoe blades. It is named that way because the smooth and uniformly ji-nie covered special Aoe forging structure reminds of silk crepe (chirimen).

muji-hada (無地肌): The term muji-hada is used when a jihada is not discernible because it is so tightly forged, mostly in reference to shinshintô or gendaitô blades. The steel is not actually grainless but until more recent times it was very difficult to bring out such a jihada, even after careful polishing. However, details of blades described formerly as muji can now be brought out because of improved polishing techniques. And as muji-hada is actually an oxymoron, i.e. meaning about “nostructure/hada hada,” more and more the term muji-fû (無地風), lit. “tending to show no structure,” has become established to refer to the fact that the steel technically has a hada but which is just indistinguishable.

ha-hada (刃肌): Last but not least I want to introduce the term ha-hada which is used, as the name suggests, to refer to a forging structure that is very visible in the hardened part of the cutting edge, in short in the hamon. The picture below shows a Ko-Hôki blade, a school where you always can expect to see ha-hada. In this context it must be said that the course, border, and/or appearance of the hamon is actually influenced by the “underlying” forging structure. That means a smith just can’t apply any kind of hamon to any kind of jigane, or at least the result will be very difficult to foresee if these two elements are not going hand in hand. The intention behind and control of the smith in the interplay between steel and hardening is actually a highly sophisticated subject and an important factor when it comes to draw conclusions on his skill and (artistic) aim. As mentioned before, it takes a while to comprehend what is natural and unaffected, what is an excellent recreation of naturalness, what is a decent try to do so, and what is just incoherent. And for this you have to hold the blade in hands, that means it is impossible or next to impossible to draw such conclusions on the basis of a few pictures.

ha-hada

This was now an overview of the most common forging structures and I will point out characteristic features, peculiarities, and similarities later in the individual chapters on the schools. A third jigane part will follow soon that introduces the different forms of utsuri before we go over to the introductory chapter on hamon .

e SWORDSMITHS OF JAPAN

eTitle

The eBook version of the just revised Index of Japanese Swordsmiths is now available as e Swordsmiths of Japan (see link here). I made a revision, not an entirely new book, so everyone who has purchased the initial e Index of Japanese Swordsmiths should be able to download the revised edition from their Lulu account for free. However, Lulu changed their eBook publishing system a while ago and those who got the e version of this publication before that time were quasi cut off from future free downloads of revisions. So my suggestion: All those who purchased the e Index of Japanese Swordsmiths, please try to download the revision. If it works, everything is fine as you got it after the change. If it says “This eBook is no longer available for download.”, please get in touch with me via “markus.sesko@gmail.com” and I will provide you with further information about how you get your free revision via a filesharing programm. I kindly ask you to provide me with any info that you indeed got the initial eBook. This is just to keep handing out free copies within limits as this project represents years of hard work and should therefore be remunerated accordingly. I will not stubbornly insist on any “hard evidence” and handle this on the basis of trust. Apart from that, I will keep your emails on file so that I can provide you with any further updates in the future. Thank you.

NEW: SWORDSMITHS OF JAPAN – 3 Volumes

It’s done. The revised and enlarged three-volume hardcover set SWORDSMITHS OF JAPAN AKI-KUNI, KURA-SANE, and SATO-ZEN, formely titled Index of Japanese Swordsmiths, is out now and finally easily available outside of Europe! It is letter format, black & white on cream paper, a tan linen hardcover with a glossy dust jacket, and each volume has about 500 pages. The real thing looks, except for the changed title, pretty much like my test print introduced earlier here (or see picture below).

TestPrint

As for kotō, shintō, and shinshintō smiths, this publication qotes the wazamono ranking that goes back to revised edition of the 1815 published list of wazamono of the Kaihō Kenjaku (懐宝剣尺), and the so-called Fujishiro Ranking used by Fujishiro Yoshio and Matsuo in their 1935 publications Nihon Tōkō Jiten – Kotō Hen and Nihon Tōkō Jiten – Shintō Hen. When it comes to gendaitō and especially WWII-era smiths, this publication includes the ranking of about 300 contemporary smiths carried out by Kurihara Akihide (栗原昭秀) in 1942 under the title Seidai Tōshō Iretsu Ichiran (聖代刀匠位列一覧). In addition, also the five ranks and the special rank of the sixth national sword making contest, the Shinsaku Nihontō Denrankai (新作日本刀展覧会), from 1941 are quoted where about 250 swordsmiths were awarded. Apart from that, I also added the info if there are blades designated as kokuhō and/or as jūyō-bunkazai by a smith (marked by two different symbols).

As indicated in my update posted the other day, I am now more flexible with pricing and offer the set for 179.70 USD (59.90 USD each) instead of the initial 280 USD for the two-volume set. Also the timing is pretty good right now as there are four days left of Lulu’s Mother’s Day sale that saves you 20% on print books. So please use code MOM20 until May 10th to make use of this great offer. Please give me a few more days to finish the eBook version as I have to unite the three volumes into one file.

Preface to the Revised Edition:

“Three years have now passed since I published my two-volume Index of Japanese Swordsmiths and, although it seems to be a pretty short period of time for a second edition, it was indeed necessary for several reasons. First of all, the English version contained left-over fragments of the German version and just too many typos that were missed in the proofreading. This brings us to the second reason for the early update, the layout. It was brought to my attention that the font was just too small to work comfortably with the two volumes. And the third and most important reason for the early update is the fact that the initial English version was never made available to the international market as it was supposed to be. After struggling with makeshift options to make the set accessible to non-European readers, and with the aforementioned shortcomings in mind, I decided that it was time to tackle a revision. First of all, the layout was changed and a different, larger-sized font and even larger capitalized headers (i.e. smith names) which mark each entry were chosen. Due to new reference material not available at the time the initial edition was published, the revised edition was enlarged by more than 300 gendaitō, but of course several other smiths were also added who were missed the first time round. In addition, historic portraits of smiths, about 400 photographs of contemporary smiths, and pictures that contribute to the understanding of an entry were added. This resulted in an increase of about 600 pages which therefore made it necessary to split it up into three volumes. I also integrated the overview of nyūdō-gō used by the swordsmiths to enable the (non-ebook) reader to find smiths on the basis of their pseudonyms. Last but not least, a different title had to be chosen, on the one hand because the now longer set represents more of an encyclopedia of swordsmiths rather than an index, and on the other hand to avoid issues and confusion with the initial publication. With this, I hope that the revised and enlarged Swordsmiths of Japan becomes the standard work in the West for research on Japanese swordsmiths as it is still the only comprehensive non-Japanese publication of its kind.

KANTEI 2 – JIGANE & JIHADA #1

With this post, we are entering the second step in kantei, following the traditional approach indicated at the very beginning of the series (i.e. sugatajiganehamon). As mentioned back then, the steel – jigane (地鉄) – allows us in the ideal case to identify the area of production and/or the school. Well, things are of course fluid, that means everything from so “featureless” that it is even hard to tell if kotô, shintô, or shinshinto to a very characteristic steel or forging structure that allows you right away to name the smith who made the blade is possible. This brings us to the point where I have to mention that the chapter jigane actually consists of two chapters, that is to say the already mentioned steel, the jigane, and the forging structure, the jihada (地肌), or short just hada.

*

2.1 Jigane

 

Before we start, we have to address a crucial point when it comes to jigane, namely the polish. Depending on factos like the age of the polish, the skill of the polisher, and the use of various ways to finish the ji, the appearance of the jigane can vary greatly, even if you are comparing two indentically interpreted blades from the same smith side by side. So my tip is, try to focus on what should be recognisable regardless of the finish of the polish, and that is the density and the pattern of the forging structure. Well, this tip does not work when the polish is too old or bad, and if you can’t see any details in the steel, you have to skip this step anyway. Rule of the thumb is: The more uniform the jihada, the better the skill of the smith. That means a jihada might be mixed with areas of different forging structure but these areas should never stand out in an unnatural manner. So if you have a blade with a tight hada all over that shows very coarse, rough, or inhomogeneous structures just in one area, you can assume that this was not intended, i.e. that the smith lacked skill. Another possibility is that you recognize areas that don’t show any visible forging structure at all or areas without a visible forging structure that are surrounded by rougher, standing-out areas. If so, it is very likely that the core steel (shingane) comes through and that the blade had seen some polishes in its life. Please note that certain similar appearances might actually be characteristic features of a certain school or smith but this will be pointed out below or in the individual chapters. A quality feature that mostly goes hand in hand with the uniformity is the fineness of the hada but that does not mean that a larger structured hada is of a lesser quality. In other words, a swordsmith was “embedded” into his scholastic background what means that a Yamashiro man followed a different approach in forging than a Sôshû man. So the outcome, i.e. the degree of uniformity and constant quality speaks for the skill of a smith and not the technical approach in general.

So first of all, let me introduce the standard terms that have become established to refer to the different appearances of the jigane and the jihada. Basically we use the prefixes ko (小) and ô (大) to say if a forging pattern is noticeably smaller or larger strictured respectively. For example, an itame-hada can appear as ko-itame, as itame, or as ô-itame, that means here it got common to refer to a medium-sized forging structure just by its name and not to as by the prefix chû. There are of course schools of thought, like for example at the Hon’ami school, where they explicitly speak of a chû-itame or chû-mokume but today, most drop the prefix chû in this respect. Apart from distinguishing between a ko, normal-sized (chû), or ô forging structure, we also speak of a fine or dense hada, in Japanese komakai (細かい) or tsunda (詰んだ). Or also terms like seibi (精美) are in use to refer to a hada that is very fine and beautiful. Well, I am aware of the fact that there are subtle differences between a “fine” and a “dense” hada but I don’t want to overcomplicate it for the moment. The opposite of a fine hada is a rough (arai, 荒い・粗い) or standing-out (tatsu, 立つ) hada. That means in such a case, the individual layers of the steel are clearly visible. Again, a “rough” hada is not the same as a “standing-out” hada as the former term is more used to describe an “unnaturally” rough hada and the latter to refer to something that was intended by the smith, i.e. a result of his approach in forging the steel. Besides of that and not addressing the forging structure but the steel itself, we also speak of a strong (tsuyoi, 強い) jigane when the jihada is very visible at a glance and accompanied by plenty of ji-nie. A strong jigane is usually associated with blades made in the Sôshû tradition where the large amount of ji-nie and chikei result in very present features. The opposite of that is a weak (yowai, 弱い) jigane where the jihada is hardly visible and shows no or only very little ji-nie. Basically, and with the exception of certain schools (e.g. the Kiyomaro school that revived the strong Sôshû jigane), shinshintô blades are described as having a weak jigane as not much is visible in their steel. But there is more when it comes to describe the appearance of the jigane. The steel can also be either clear (saeru, 冴える) or subdued (shizunda, 沈んだ) whereas in the latter case we also speak of a “dull” or “cloudy” (nibui [鈍い] or nigotta [濁った]) jigane. Dull or cloudy means that a steel remains to be matt in larger areas even if polished. Or in other words, even if it is tried to enchance the ji with certain polishing methods, a dull or cloudy steel will never turn out to be super bright. And when the steel looks “wet,” i.e. kind of moisty even if perfectly freed from oil, we speak of uruoi (潤い). And last but not least we distinguish between a noticably dark or blackish (kuroi, 黒い) or whitish (shirake, 白け) steel. The former is typical for blades from the farther north or south regions, that means from the so-called Hokkoku region (北国, production sites along the Hokurikudô) or Kyûshû respectively. Accordingly, also the term hokkoku-gane (北国鉄) is in use to refer to a darker, “northern-style” jigane. As for shirake, basically later Mino, i.e. Sue-Seki blades are known for showing much shirake but a little shirake is seen at many other schools and this will be pointed out in the individual chapters. By the way, shirake is often a way to distinguish offshoots from the schools they came from. That means, if you have for example a blade that looks like Rai at a glance but that just shows too much whitish shirake in the ji, think about a school that derived from Rai, e.g. Enju or Ryôkai. And the overall quality of the work should tell you how far away you are from the “real thing,” i.e. are you facing a direct student of one of the great masters? Or is the workmanship already that inferior to assume that it is a work of a student of this student or of an even later smith from a local offshoot?

In direct continuation of talking about the steel, I want to introduce first the features, the hataraki that can occur in the jigane before introducing the different forging structures. Well, strictly speaking, some of them might be associated with the jihada but they should be introduced here too for reasons of clarity and convenience.

ji-nie (地沸): Ji-nie is probably the most common feature in the jigane and seen to some extent in any sword. As the term suggests, we are talking about visible martensite particles (nie) that occur in the ji. Ji-nie can be pretty fine and evenly distributed over the blade or concentrate in certain areas and if these areas appear in a connected manner over a certain distance (or along the entire ji for example), i.e. in a way to recognize a certain “unity” or patch, we speak of a nie-utsuri (but please see section utsuri for more details on this term). As for ji-nie, the same rule applies as for the jigane, that means we speak of a high-quality ji-nie when it is fine and uniform or when it was deliberately applied, i.e. when for example a partially rough and accumulating ji-nie was the style in which the smith worked. Also we must distinguish between if a sword was intended as mere weapon or if there was a real artistic approach behind making that blade. So if you have a late Muromachi-era blade from one of the then sword centers that shows rough and unnaturally accumulating ji-nie, it is safe to assume that smith was just lacking skill. But if you have a shinshintô blade with a rough and unnaturally accumulating ji-nie that should somehow represent a work from one of the great Sôshû masters, the element “lack of skill” has a slightly different connotation. In other words, the smith might had been indeed very skilled but than Sôshû was not his thing or he just started to experiment towards Sôshû. So depending on what the intention of making a blade was we have here different standards of appreciation. Just one example, very rough and obvious ji-nie is “accepted” for the Satsuma smiths because this was their style.

chikei (地景): Chikei are black gleaming lines in the ji that are basically layers of steel with a different, higher carbon content. So chikei follow the layer structure of the jihada and are virtually the same as kinsuji, just with the difference that they occur in the ji and not in the ha. As a rule of thumb: The more chikei are present the more it is likely that a blade was made following the Sôshû tradition of sword forging, i.e. deliberately mixing steels of different carbon content. Please note that there is also another way the term chikei can be used and that does not refer to layers of steel but to a hardening effect. In other words, it is used to refer to ji-nie that forms formations similar to mokume-like burls but which are not tied to the layer structures of the jihada. Well, some say that they actually are tied to the layers and we are speaking here of the same thing, i.e. the former explanation of chikei used to refer to the “obvious” layers of different carbon content in the steel and the latter to much finer layers which are not recognizable for the naked eye as layer structures and thus seem not to be connected to the structures of the jihada. But I don’t want to split hairs here (the subject of chikei might fill a blog entry itself) and when I refer to chikei, I mean black gleaming lines in the ji, period. (Please click on pic below to get a larger and clearer image).

yubashiri (湯走り): Yubashiri are isolated spots or patches of ji-nie that remind of water droplets. They are similar to tobiyaki as they occur detached from the hamon but as they consist of nie and are not embedded into a cloud of nioi, they have a more transparent look and not so clear borders as nioi-based tobiyaki. Due to the fact they consist of nie, yubashiri are of course seen on blades that are hardened in nie-deki or at least with much nie. So they are similar to tobiyaki but not the same. Yubashiri often concentrate along the habuchi and create there more linear appearances that remind of nijûba. We see them on Kamakura-era Yamato, Yamashiro, or Sôshû works or at later blades aiming at such works.

jifu (地斑): Jifu are areas where ji-nie occurs as a “closed mass,” i.e. as patch or stain. For example, we find descriptions like “plenty of ji-nie that tends to jifu in places” what basically means that these areas full of concentrated ji-nie give the blade a spotted appearance. But the term jifu, lit. “spot/splotches on the ji,” is rather ambiguous and different scholars use it to refer to different features. For example, some refer with it to areas of exposed shingane, for which in turn the special term ji-zukare (地疲れ) exists. And the “showing through” (sunda, 澄んだ) shingane in turn resulted in the creation of the term sumigane (澄鉄) or sumihada (澄肌). Another term for the same feature is, in special context of the Aoe school, namazu-hada (鯰肌) as these patches remind of the slimy, scaleless, smooth and dark skin of a catfish (namazu). And also the term Rai-hada (来肌) is in use when it comes to Rai blades with this characteristic feature. In other words, these terms were born from the necessity to name similar features differently depending on which school it occurs so that you have a more sophisticated nomenclature to work with. In a nutshell, when someone talks about “dark spots in the ji” it might be difficult to know what is meant but when this person uses the terms namazu-hada, or Rai-hada, everybody knowns right away that he or she is talking about Aoe or Rai blades respectively. It is assumed that the feature sumigane, namazu-hada, or Rai-hada goes back to the fact that the corresponding schools made blades with a relative thin kawagane what exposes the shingane core steel rather quickly. Well, there is still discussion about if these features, or Rai-hada in particular, are exposed core steel or just inhomogeneous but in itself homogeneous and darker parts of the steel but from my subjective point of view, I think they might be shingane but with the difference that we are talking here about top quality blades what in turn leads me to think that even their core steel was of better quality and looks thus slightly finer when exposed and not at a glance like ji-zukare for example seen on a Sue-Seki blade. Anyway, this feature, i.e. sumigane, is also found on blades of the Un group (雲), the Enju school (延寿), the Mihara school (三原), of Osafune Motoshige (元重), and on early Echizen blades like for example of Chiyozuru Kuniyasu (千代鶴国安) and Hashizume Kunitsugu (橋爪国次).

In conclusion it must be repeated that the jigane is a pretty sensitive subject and it needs some experience to be able to disregard or block out the condition of the polish and draw conclusions on what you would see with a perfect polish. That means certain features like yubashiri or finer ji-nie might just not be visible at an older polish. In other words, and this might make me sound like captain obvious, you should focus on what you see, i.e. you should not get lost in trying to figure out if a certain stain is yubashiri or jifu when the condition of the blade just does not allow such a conclusion. Also there are kind of preferences when it comes to judging Japanese swords: Some (like me) attach great importance to the sugata whilst others have a natural access to the steel and just need to look at the jigane and jihada to say which school or smith made the blade. And last but not least it turned out at our local sword meetings that light from a fluorescent tube is very good to see the steel (but not certain details of the hamon) but also sunlight does a pretty good job.

In the next part (2.1) we continue with the different forms of jihada, followed by a chapter on utsuri, before we end part 2, the steel, and go over to part 3, the hardening.
