This listing features a tanto by Kenryushi Sadaharu, dated to February of the 4th year of Meiji (1871). Sadaharu, a student of Gassan Sadakichi, was a swordsmith who forged blades for the last samurai, alongside his fellow disciple Gassan Sadakazu, who later became an Imperial Household Artist. The blade exhibits a strong awareness of old works, with a reduced length, thick kasane, a withered fukura, and a distinctive boshi.
