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 powerful tachi made by Yasuaki (Masuda Kaname), a Yasukuni Tosho born in Tochigi Prefecture in 1915. He was one of 12 Yasukuni smiths who received the name 'Yasuaki' from General Sugiyama in 1944, forging Yasukuni Shrine dedication swords and military swords. After the war, he resumed sword making in 1953, winning numerous awards. This tachi features a strong form with an extended kissaki, well-forged ko-itame hada with ji-nie and fine chikei, and a bright nie-deki hamon of gunome and gunome-choji with occasional togari-ba, rough nie along the habuchi, well-entered ashi, and kinsuji and sunagashi.
