The twentieth century nearly killed the craft twice: wartime distortion, then the occupation ban. The NBTHK’s founding in 1948 and licensed forging from 1953 rebuilt the sword as an art, crowned by Living National Treasures and the mukansa rank.
This is a tanto by Zuiunshi Yoshisada, whose real name was Yamamura Shigematsu. Born in 1900 in Kochi Prefecture, he was a swordsmith from Tosa. He studied under Yamamoto Yoshimori and Kawashima Chuzen (Mukansa Tosho), creating works comparable to the famous 'Sagyoshu' of Tosa and Bizen-den pieces signed Tosa Ichimonji. This particular piece is a Hosho utsushi (copy) with a beautiful masame hada.
