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.
Seto Yoshihiro, born in Fukuoka in 1945, is a Mukansa swordsmith who studied under Sumitani Masamine. He is renowned for his Bizen Ichimonji style, having won numerous awards for his work. This tachi, made in 1993, features a wide body, deep bo-hi, and a high koshi-zori, reminiscent of Kamakura period blades. The jigane is well-forged ko-mokume, and the hamon is a vibrant choji with intricate patterns, reflecting the smith's mastery.
