Japanese wakizashi, the hilt of the wakizashi consists of two pieces of wood joined together longitudinally to form the grip. The wooden grip is covered with white ray-skin and is secured to the tang near the top by a short bamboo rod. The bamboo rod is bound with a piece of twisted bright blue silk. The hilt of the wakizashi is decorated with ornaments (menuki) made entirely of gilt. The ornaments (menuki) are made in a tripartite form, each part bearing an embossed gilt representation of a paulownia blossom spray on a bronzed ground. The pommel (kashirm/kashire, but strictly speaking, kabuto-gane) is a made in the form of an outline of a crested double ogee with a pierced space each side. The pommel (kashirm/kashire) is made of bronze copper with gilt wire decoration embossed on its stippled surface and round the edge of the pierced space. At the top, on a horizontal band is a disc, pierced to admit the silk binding, which is knotted above it. The ferrule (fuchi) is also made of bronze copper with gilt wire and has a copper top to admit the tang.

The steel blade is slightly curved; it is heavy with a single edge with an offset ridge running nearly the whole length. The back of the blade is ridged all the way to the long curved-edge point. The temper-line is (probably) of the irregular 'box' formation and ends at the point in the large-cicule way. The tang is of the pheasant's thigh configuration, and is engraved on the reverse with the signature in Japanese of 'YOSHIMITSU'. The obverse of the blade is not engraved. The shoulder of the blade is encased by a copper collar (babaki); 28mm, which is plain, save for the back edges, which are scratched. There is a single rivet hole in the tang. The scabbard is missing. Yoshimitsu of Tosa Province, Japan, a pupil of Sa Yukihide, probably made this sword's blade some time between 1840 and 1855.
