Mamoru Shinano, Hisahiro Muto, was a swordsmith of the Dotanuki Sue school who studied swords under Dotanuki Munehiro, and wielded a hammer as a smith of the Tachibana clan of the Yanagawa domain. The flow is still inherited by modern swordsmiths who are active in Fukuoka Prefecture.
This sword has a well-kneaded and clogged small-grained skin, and has a bright and clear straight blade that is similar to a small boiling point. It is a gem, and it is a work that fully demonstrates the skill of Kuhiro who was active as a Yanagawa feudal lord.
