The competent smith is the second generation Okamoto Kuniyoshi, who was retained by the Kato clan of Mutsu Province. He studied in the schools of Ozaki Sukataka following the first generation, using at one time the name Sukekuni, and also studied under Hoki no Kami Masayoshi. This was around 1804-5, a few years before his father's death. He died in 1845. The inscription states that the blade was commissioned by one Nagase Tsuguhiro.
