Features: Although the sayagaki by Takase Ugao attributes this blade to Sadayoshi of Chikuzen Province, the Japanese Sword Museum (NBTHK) attributes it to Osafune Shigemasa. The jigane displays a prominent surface grain that is clearly visible, making the attribution to Osafune Shigemasa appear more convincing. Shigemasa was active from the late Kamakura period to the early Nanbokucho period and is said to have been either the younger brother or a disciple of Motoshige, with a closely related style of workmanship.
