Sengoku Seki was an industry: smiths organized under their tutelary Kasuga shrine, arming the war bands of central Japan. Magoroku Kanemoto’s sanbonsugi and the finest Kanesada work prove quality survived inside mass production.
This is a tanto attributed to the Tsoshinaga school, dating to the late Muromachi period. The blade features a bright hamon with a pattern resembling "Sanbonsugi". It comes with a Hozon certificate, a copper habaki, and a shirasaya.
