This is a mumei wakizashi attributed to Uda Hirakuni from the Etchu province. It features an unokubi-zukuri shape with iori-mune, and a suriage nakago. The blade exhibits a ko-itame hada mixed with masame, with ji-nie and chikei, and a midare-ba with shallow notare, well-formed ko-nie, kinsuji, and sunagashi, resulting in a bright and clear appearance. Both sides have koshi-hi with a single suji-hi carving. It is a good example of a Sue-Koto blade and comes with NBTHK Hozon Token papers.

Where Ko-Uda closes with the Nanbokuchō generations, the chapter that follows opens in early Muromachi and runs to the end of the period. The setsumei draw the boundary plainly: works that descend no later than Nanbokuchō are called Ko-Uda, while everything thereafter is referred to simply as Uda. This later phase is the long Muromachi continuation in Etchū, where the Kuni-named line that began with Ko-Nyūdō Kunimitsu of Uda District in Yamato extends across successive generations sharing single names.

Certifies a genuine blade worth preserving: a signature confirmed correct, or, if unsigned, an era, province, and school that the NBTHK can reliably identify.

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.
