The Haitōrei edict of 1876 ended sword wearing and nearly ended the craft itself. Military demand and imperial patronage kept a remnant alive, and in 1906 Gassan Sadakazu and Miyamoto Kanenori were named Artists to the Imperial Household.
This is a rare tanto by Ishikawa Masamitsu, a swordsmith who served the Tsuyama domain in Mimasaka province. Dated to 1870 (Meiji 3), it is a valuable piece from the final period of the domain's existence. The blade features a hirazukuri shape with a thick kasane, koitame hada, and a vibrant choji-midare hamon.
