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 Gassan Sadakazu, a Living National Treasure, made during his early period under the name Takateru. It features an inscription related to the Imperial Grand Shrine and intricate carvings, a specialty of the Gassan school. The blade is a commemorative piece ordered by a renowned sword collector and is certified as Tokubetsu Hozon by the NBTHK.
