Shape: This Ōmiya blade is characterized by a substantial width and thickness, a deep curvature, and an elongated tip. It exhibits traits reminiscent of the Enbun-Jōji period.
Jigane: The itame hada (wood grain pattern) with mokume hada (burl grain pattern) is clearly visible, and the jigane has a distinct jigane (forging texture).
Temper Pattern (Hamon): The hamon displays nie (crystalline structures) with abundant ashi (short lines) and activities such as sunagashi (sand-like lines) and kinsuji (golden lines). The hamon widens gracefully towards the tip, where it becomes more intricate and returns to a gentle pattern.
Special Features: Although this piece may appear as a straightforward blade, the flow of the hamon towards the tang suggests that it was part of a longer sword. It is believed that longer blades were popular during the Nanboku-chō Period.
From Aoi Art: The Ōmiya of this work notably exhibits excellent jigane that has been meticulously polished. The jigane is prominently visible, showcasing its quality. The hamon exudes a soft smoky appearance with the effects of sunagashi and kinsuji, making it a splendid piece. This is a work that we highly recommend.
