This Japanese wakizashi sword from the koto period displays a blade (nagasa) length of 48 cm (including scabbard: 69 cm), crafted in the classic shinogi-tsukuri shape with torii-zori curvature and gyo-no-mune (iorimune) back. The blade tip (boshi & kissaki) shows a komaru boshi, barely distinguishable, with a chu-kissaki, and the temper line (hamon) exhibits both suguha-midare and ko-midare patterns. There are no grooves (hi or horimono) present, while the grain structure (jihada) reveals a combination of masame and itame on the omote side. The blade, dating to the koto period, is noted for its excellent condition and very fine polish.

The tang (nakago) ends in a kiri tip and features kiri yasurime file marks, with two peg holes (mekugi-ana); it bears no signature (mei). The mounts (koshirae) comprise a hilt made of rayskin over wood, wrapped in black silk, with iron menuki formed as a branch adorned with five gold-plated blossoms. The guard (tsuba) is shakudo-nanako in Mokko form, with a floral decor in shakudo, copper, and gold, while the fuchi-kashira are similarly shakudo-nanako, ornamented with stylized branches. The blade collar (habaki) is blackened copper, accompanied by two gilt washers (seppa). The kozuka is shakudo-nanako, blackened, decorated with stylized five-petaled blossoms in gold and marked with Kikyo-mon; the kogai is made as the kozuka, also signed Kikyo-mon. The scabbard (saya) is finished in black, finely sprinkled lacquer, adorned with stylized blossom motifs, including three stylized blossoms (two in gold and one in black) as well as fittings—koijiri, kurigata, ushiro, semegane, and kugikakushi—in shakudo and gold.
