| This tachi was designated as Juyo Token (Important Sword) at the 24th NBTHK Juyo Token Shinsa in 1976, under the designation "Tachi, Bishu Osafune ju Shigesane." Shigesane is said to have been the son of Saemon no Jo Morishige, the younger brother of Motoshige, and a disciple of Kagemitsu. Dated works by Shigesane range from the Karyaku era (1326–1329) to the Oei era (1394–1428), suggesting that the name was carried on through three or four generations. However, a sword dated to the Kenmu era (1334–1338) bears a signature closely resembling that of this tachi. Furthermore, judging from the workmanship of the hamon, this tachi is believed to be the work of the first-generation Shigesane, who is considered to have been either a disciple or the younger brother of the first-generation Motoshige. (Reference: Kanto Hibisho, Zoku.) Signed works by Shigesane are few and therefore rare. The sayagaki (inscription on the scabbard) by Kunzan sensei reads: "Bishu Osafune Shigesane. Circa Kenmu era. Suriage (shortened). Blade length: 2 shaku, 4 sun, 7 bu. Inscribed by Kunzan in February 1988 (with kao)." |
