A large mokko-gata katana tsuba. This tsuba has a deep black patina with a wet luster. The theme is that of ken and hishi (sword blades and diamond). This work was attributed to the Kyo Shoami school by the NTHK. The paper states that it was made in the early Edo period. So this dates to around 1600-1650. The patina of this tsuba is especially pleasing and it is a large work. Accompanied by an NTHK paper and a paulownia wood storage box.
