It is said that the first generation Hiromasa was a person of the Nanbokucho period, but no extant works exist. This work is likely the third generation Hiromasa of the Oei era. The hamon is hitatsura-style near the habaki-moto with active ashi and yo, and nie-ashi enter all the way to the ha-saki. The jigane is a well-refined ko-itame hada, and the quality is excellent.

Certifies a genuine blade worth preserving: a signature confirmed correct, or, if unsigned, an era, province, and school that the NBTHK can reliably identify.
The NBTHK (Nihon Bijutsu Tōken Hozon Kyōkai, the Society for the Preservation of Japanese Art Swords) is a public-interest incorporated foundation founded in 1948 and supervised by Japan’s Agency for Cultural Affairs (Bunkachō); it is based at the Japanese Sword Museum in Tokyo. Its expert panels physically examine each submitted work (shinsa) and issue a certificate (kanteishō) ranking it by artistic and historical merit. NBTHK papers are the most widely recognized standard of authentication for Japanese swords and fittings.
