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 listing features a Daisho (matching pair of swords) by Sakai Ikkanzai Shigemasa, a modern swordsmith recognized as a Mukansa (unexamined) swordsmith by the NBTHK. Born in 1905, Shigemasa trained under Kasama Ikkanzai Shigetsugu and later became a commissioned smith for both the Army and Navy. His works are known for their beautiful jigane (blade steel) and prominent hamon (temper line), often featuring intricate blade carvings.
