This is a naginata-naoshi wakizashi, originally a magnificent naginata, now attributed to the Samonji school by the NBTHK. Hon'ami Nagashoku also attributed it to Sagami Yukimitsu, the foster father of Soshu Masamune, and a sayagaki is present. The blade retains its original powerful form, displaying a vibrant hamon with intricate activity reminiscent of Samonji or Soshu Yukimitsu.

Kamakura fell in 1333, but the school’s greatest era followed: Sadamune working at his teacher’s standard, Hiromitsu and Akihiro spilling hitatsura over the whole blade, and the Sōshū manner spreading with the armies until it became, for a time, a national style.
A Hozon-certified blade judged to show notably superior workmanship and a better state of preservation. The bar is higher: re-tempered blades and most unsigned Muromachi/Edo works are excluded.
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.
