Update: As a reference, I compiled a brief booklet that contains all 27 sword fittings that are by today designated as jûyô-bunkazai, enlarged by 28 items that got jûyô-bijutsuhin. As mentioned, it is just a reference for those who always wanted to know what kind of sword fittings and tsuba are regarded by the Japanese government, or Bunkachô in particular, as being of greatest importance. The booklet comes in color and is in letter format. Price is just a little more than the printing costs and I also uploaded an eBook version of course (see links below). Thanks for your attention!
