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.
The real name of the swordsmith Kono Sadamitsu was Kono Hiroshi, born in Showa 25, and he lived in Shimohonjo, Saigawa-machi, Miyako-gun, Fukuoka Prefecture. Initially, he studied swordmaking under his biological father, the first generation swordsmith Kunimitsu (Sa Kunimitsu) (Buzen Ju Kono Kunimitsu), and for that reason, Sadamitsu first used the name (Sa Kunimitsu Nidai). Later, in Showa 50, he became a student of the late Living National Treasure Gassan Teiichi and trained in swordmaking and toshin-bori. His high level of skill was recognized by the late Gassan Teiichi, and he was granted the character "Sada" by his master, after which he signed as "Sadamitsu." A swordsmith dedicated to research, he pursued the original function and functional beauty of the nihonto—to be unbreakable, unbending, and to cut well—and he is praised as the foremost among modern swordsmiths for sharpness, called the Kotetsu of today; he has an established reputation for the beauty and sharpness of his work and is highly evaluated by martial artists. Since the passing of Sadamitsu, his popularity has increased even further. He received many awards, such as the Doryoku-sho at the Shinsaku Meito Ten. Works signed as Ishidanmaru have a slightly wider mihaba compared to usual, hi are in principle not carved, the hiraniku is well-applied, and they have a slight hamaguri-kokoro. From this taihai, it is indeed a sword suited for cutting hard objects.

Shōwa to the present: destruction and revival
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.
Certifies a genuine blade worth preserving: a signature confirmed correct, or, if unsigned, an era, province, and school that the NBTHK can reliably identify.
The NBTHK (Nihon Bijutsu Tōken Hozon Kyōkai, the Society for the Preservation of Japanese Art Swords) is a public-interest incorporated foundation founded in 1948 and supervised by Japan’s Agency for Cultural Affairs (Bunkachō); it is based at the Japanese Sword Museum in Tokyo. Its expert panels physically examine each submitted work (shinsa) and issue a certificate (kanteishō) ranking it by artistic and historical merit. NBTHK papers are the most widely recognized standard of authentication for Japanese swords and fittings.
