Jigane: The ko-itame hada is well-forged and tightly constructed, resulting in a refined surface.
Hamon: A nie-deki hamon starts as suguha at the hamachi, transitioning into gunome-midare and koshō-chōji (fist-like chōji) patterns, with the boshi dipping and returning in a rounded form.
Features: This sword is referred to as "Nakakawachi" because it bridges the first and third generations of Kunisuke. Known for mastering chōji-style hamon, Kunisuke is sometimes referred to as "Shinto Ichimonji" for his excellence in this area.
Aoi Art’s Comment: During the Kanbun Era, the Tokugawa shogunate issued successive bans on townsmen wearing swords, leading to the unemployment of many swordsmiths, who transitioned to general blacksmithing. The third generation of Kunisuke closely followed the second generation's style and is said to have produced numerous works under the second generation's name. This particular piece is an authentic work of the second generation, featuring the prominent koshō-chōji (fist-like) hamon for which he is renowned.
