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 tanto by Gassan Sadatoshi, a Mukansa swordsmith born in 1946 as the third son of Living National Treasure Gassan Sadakazu. Made in 1984, this carefully crafted tanto features the distinctive Ayasugi-kitae of the Gassan school, with large Itame and Mokume patterns forming a wave-like Ayasugi texture. The blade also features intricate carvings (horimono) by Sadatoshi himself, depicting a Sanko-tsuka Ken on the omote and a Shobu-style hi with soe-hi on the ura, making it a superb example of his work.

Without one, the attribution is the seller’s own assessment and has not been independently verified — treat it with caution and ask the dealer about certification before buying.
