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 Tachi is a work by Sanryūtei Ryōsanshi Masamine, a Living National Treasure, forged in August 1975. It features a wide blade with thick kasane, bohi carvings, and a nie-based gunome-midare hamon. The blade comes with an NBTHK Tokubetsu Hozon Token certificate.
