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 made by Yoshiharu (Shinbo Kiharu), born in Sado Ryotsu, Niigata Prefecture in 1941. The blade features a hirazukuri shape with a koitame jitetsu and chu-suguha hamon. It is a powerful work created by Yoshiharu at 35 years old, replicating the style of Rai Kunimitsu from the Kamakura period.

We could not find an authenticity certificate on the seller’s listing. Japanese swords and fittings are normally papered by the NBTHK (or the NTHK). 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.
No cooling-off period or returns; refund only if the purchased sword is proven fake, capped at purchase price (excludes commission sales, accessories, auction items).
