Hon'ami (Kaō) (Kōryō)
金粉銘　 金重(きんじゅう）
本阿弥（花押）（光瞭）

Features: Kinjū moved from Echizen Tsuruga and, alongside Shizu Saburo Kaneshige, contributed to the development of the Mino smithing tradition.
His works are extremely rare.
His jigane resembles itame, and his hamon features small, controlled gunome midare, largely resembling that of Shizu Kaneshige.
The nie structure is magnificent, with brilliant kinsuji streaks adding an extraordinary touch to this sword.
