The sword is gassaku wakizashi, a collaboration of Tsunatoshi with his son Koretoshi. Such blades were quite common during the last year of Tsunatoshi’s life.

Tsunatoshi, whose real name Katō Hachirō, came originally from Yonezawa (Dewa) and was, like his father Katō Kunihide, a student of Suishinshi Masahide, founder of shinshinto style. During the Bunsei era (1818-1830) Tsunatoshi moved to Edo, where he worked for the Uesugi family, daimyō of Yonezawa; in 1854 he left his gō “Chōunsai” (長運斉) to his second son Koretoshi and changed his pseudonym to “Chōjusai” (長寿斎). He died in 1863 in the Uesugi Edo residence at the age of 66. After his death, Koretoshi started signing as second generation Chōunsai Tsunatoshi

Like his brother Tsunahide, Tsunatoshi worked in tōran-midare and this blade is a typical example of his production. His jigane is a dense ko-itame with ji-nie which tends to muji, the hamon is generally in nioi-deki with tight nioiguchi. The bōshi is a smaller midare-komi, the jihada can also be a dense mokume which tends to muji but which also show mixed-in ō-hada. Blades have generally a deep sori and a thick kasane.

He is rated jō-saku by Fujishiro.
