Aoi Art’s Comment: The jigane of Kouta often features itame and masame grains that stand out, with a hamon characteristic of the Soshu tradition, showing deep nioiguchi. Many works also have rounded boshi. This piece displays similar craftsmanship, with no bo-hi on either side, allowing a clear view of the shinogi-ji that reflects its age. Additionally, the hamon exhibits a darkly flowing chikei, accentuating a distinct grain pattern and demonstrating a deep and lively nioiguchi.
