This blade displays a well-executed choji hamon in Ichimonji style, with excellent craftsmanship and superior jigane.
Masame pattern appears in the shinogiji.

Historical Background:
As the Muromachi period gave way to the Edo period, the shape of swords changed significantly.
This piece reflects the Kanbun Shinto style, characterized by a longer boshi.
In Mino province during this time, the production of tanto decreased dramatically due to low demand, leading smiths to focus on katana and wakizashi.
This work, clearly aiming to emulate the Ichimonji style, was skillfully produced in such an era.
It is believed that the smith worked wherever he could to survive, producing swords with determination.
