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 signed Gassan Sadakatsu with a Showa date. The sword features a ko-itame hada mixed with masame and a gunome midare hamon in nie deki. It is described as being in excellent polish and in flawless condition.
