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 Ken (sword) made by Amata Akitsugu, a Living National Treasure and one of the highest-ranking contemporary swordsmiths. Born in 1927, Amata Akitsugu was renowned for using self-produced steel and mastering various traditions, including Yamashiro, Soshu, and Bizen. This particular piece is a Ken crafted in the Yamato tradition, featuring a finely forged ko-itame hada and a flawless suguha hamon, embodying the golden ratio of ancient Yamato Ken.
