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 wakizashi by Masamine (Seihou), a Living National Treasure. It is a masterpiece that faithfully reproduces the style of Kanemitsu, featuring a wide mihaba, small itamehada mixed with masamehada, clear jitetsu, gunome chouji hamon, and frequent kinsuji and sunagashi. Masamine was born in Ishikawa prefecture in 1921 and was designated an important intangible cultural property in 1981.
