Naganobu (1817-1875) was a student and later an adopted son of Jakushu Fuyuhiro XV, eventually assuming the title Fuyuhiro XVII. During the 1830's he moved to Edo where he lived in Kojiwachi, Hirakawa-cho and Sanno. Naganobu was a pupil of Chounsai Tsunatoshi and produced many blades for the Matsushiro clan of Matsue, Izumo Province.

Naganobu usually employed a ko-mokume forging pattern, as on this example. The tempering he preferred was either komidare, which was generally quite pointed, similar to togari, or gonome and he produced midare of a choji-type shape. On most of his blades the tempered edge is a combination of nioi and ko-nie.
