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 katana was forged by Isobe Ikkansai Mitsuhiro in August 1966, likely as a custom order for a new house celebration. It features a wide body, noticeable difference in width between the base and tip, and an extended kissaki. The jigane is primarily ko-itame with strong masame towards the tip, and the hamon is bright gunome with active ashi and fine sunagashi, showing small tobiyaki in places. It comes with a shirasaya and a suaka habaki, and is mounted in a koshirae with a black lacquered saya and fujimaki tsuka.
