It features a powerful, long Kamakura-like sugata with a ko-kissaki and a nice notare hamon with gunome-esque activity. The sword comes with NBTHK Tokubetsu Hozon papers and is housed in a beautifully patinated dark wood shirasaya.

The Niō school (二王) worked in Suō Province along the San'yōdō, the western reach of the country where heavy concentrations of temple estates, including lands of Tōdai-ji, drew the province into exchange with the Yamato heartland. The members describe the line as beginning in tradition around the Hōen era (1135 to 1141) with a Kiyozane or Kiyohira, but they agree that no securely attributable work by either survives, so Kiyotsuna is regarded in effect as the school's founder.
