[ Highlight ] Sukesada of Osafune was a swordsmith from the Sue-Bizen period; in response to the demand for swords during the turbulent Muromachi period, numerous swordsmiths bearing the same name established themselves on the Bizen Osafune base. This piece is a Sukesada dated to the Eiroku era; in later years, the blade was shortened by about one and a half sun and the tang was re-forged to be longer. It is a well-proportioned sword with a pleasing curvature, offering a solid grip. The steel exhibits a well-grained itame-hada texture, interspersed with mokume-grain and flowing grain, featuring ji-nie and fine chi-kei. The hamon consists of a koshi-biraki mutsu-me pattern, interspersed with chōji and pointed edges, with ashi and yo, a strong nioi-nie, and abundant nie, accented by kin-suji and sunagashi, creating a truly impressive work.
