Special Feature: Bizen no Kuni Osafune Tadayoshi, the second generation, was known as Hikobei, the son of the first generation Tadayoshi, and later succeeded the name of Hikobei.

From Aoi Art: This is an ancient Bizen sword from the time when one-handed combat, known as “katate-uchi,” was popular. During that period, there was a transition from fighting on horseback to fighting on the ground, resulting in swords with shorter tangs that could be operated with one hand, and many blades had a slight curvature and an elongated tip. From the Meiō to Eishō eras, high-quality tamahagane steel was produced, and the quality of the blades was on par with those bearing family names. This particular sword exhibits excellent workmanship with the ground steel exceeding expectations, resulting in a neatly rounded hat. The mountings are also satisfactory, presenting an elegant appearance. We highly recommend this splendid work by Bizen no Kuni Osafune Tadayoshi, featuring a prominent curvature and excellent condition.
