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 by Minamoto Yoshichika, a smith renowned for his cutting ability, and famously favored by Nakayama Hakudo, the "Sword Saint of the Showa Era." The blade features a mokume jihada and gunome hamon, with a kiritsuke-mei on the nakago recording a test cut by Nakayama Hakudo. Both the blade and koshirae are in excellent condition, making this a rare and historically significant piece.
