Signature : Oku Yamato Kami Ason Motohira
Kyowa Gan Tori Haru(Spring 1801)
奥大和守朝臣元平
享和元酉春

Sayagaki:This sword was made by Okuyamato no Kami Taira no Ason Motohira. The nine-character signature and inscription date it to the first year of Kyōwa (1801), when the smith was 58 years old, at the height of his mastery. The blade is broad with a full-bodied cross-section, a graceful curvature near the hilt, and a long, powerful tip. It exhibits the superior forging skill typical of the smith, with a finely grained ko-itame pattern, thick layers of ji-nie (surface steel particles), and chikei (surface patterns). The hamon (temper line) is a wide, intermittent gunome with sharp points, featuring a deep nioi (martensitic crystal line) and thick nie. The blade is also decorated with prominent ara-nie (large crystalline grains), sunagashi (sweeping lines of nie), nie-suji (nie lines), kin-suji (golden lines), and yubashiri (irregular streaks of nie), demonstrating the smith's mastery of the Shizu school style. The sword is exceptionally robust and outstanding.
