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 Sakai Ikkansai Shigemasa, born in 1905 and active until 1996. The blade features a beautiful jigane from skillful forging and a prominent hamon. It comes with an NBTHK Hozon paper and is housed in a shirasaya with a gold-plated double habaki.
