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 Japanese katana forged during the Showa era by a master of the Kanesada lineage from Seki City, the heart of the Mino sword-making tradition. The blade features a gracefully flowing notare-midare hamon, skillfully highlighted by a traditional high-grade polish. It is mounted in a shirasaya, ideal for protecting the blade from moisture and preserving its condition.
