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.
Bare blade weight 817 grams Showa 42 February 9 Shizuoka Prefecture registration Included: shirasaya, suaka habaki Isobe Ikkansai Mitsuhiro, whose real name was Isobe Mitsuji, was born on September 10, Taisho 4 (1915). He studied sword forging as a monjin of Miyaguchi Ikkansai Toshihiro, and along with succeeding to the name "Ikkansai" following Miyaguchi Ikkansai Tsune-toshi, he was granted the character "Hiro" from his teacher Toshihiro and signed as Mitsuhiro. Active as a member of the All Japan Swordsmith Association, he received an Effort Award in Showa 35, and thereafter continued to energetically submit works to sword making competitions, being a tosho with numerous experiences of winning prizes. He also engaged in the study of famous old swords and is known for having produced a copy of the "Myojun Denji Sohaya no Tsurugi Utsusu Nari" held by Kunozan Toshogu, which is associated with Tokugawa Ieyasu, and he continued sword making for a long time from Showa through Heisei. This katana was made in August, Showa 41, and is a hitofuri seen to be a注文打ち forged for a housewarming celebration. The mihaba is wide, there is a difference between the moto and saki widths, and the kissaki is extended, presenting a relaxed sugata. The jitetsu is based on ko-itame, but as it goes toward the saki, masame-nagare appears strongly; the hamon is a gunome with a bright nioiguchi and many ashi, with fine sunagashi appearing within the ha, and small tobiyaki can be seen in places. The boshi is midare-komi with a round kaeri, and the undulations of the gunome and the activity of the ashi are clearly captured even in the photographs. From the numerical values of motohaba 32.8 mm, motokasane 7.2 mm, and bare blade weight 817 grams, a healthy sugata with sufficient volume despite being a post-war work can be observed, making this an interesting sword for understanding the range of Mitsuhiro's work. *Consignment item
