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 Katana made by Isobe Ikkansai Mitsuhiro, who was born in Taisho 4 (1915) and was a student of Miyaguchi Ikkansai Hisahiro. The blade was made in Heisei 10 (1998) and is certified Hozon by the NBTHK. It features a blade length of 72.3cm and weighs 965g.
