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 Sumitani Masamine, a Living National Treasure, in August of the Jinshu year (1982). It features a beautiful Choji hamon, known as 'Sumitani Choji', and is accompanied by an NBTHK Tokubetsu Hozon certificate. Masamine was a renowned smith who mastered the traditional forging methods of the five traditions (Gokaden).

A Hozon-certified blade judged to show notably superior workmanship and a better state of preservation. The bar is higher: re-tempered blades and most unsigned Muromachi/Edo works are excluded.

Its expert panels physically examine each submitted work (shinsa) and issue a certificate (kanteishō) ranking it by artistic and historical merit.
