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 made by Kobayashi Yoshinaga in Showa 61 (1986). It features a wide body, shallow sori, and a chu-kissaki. The blade has a well-forged itame-hada with fine nie and chikei, and a gunome-midare hamon with nie and sunagashi. It comes in a black lacquered uchigatana koshirae with purple ito-maki.
