Shinogi-zukuri blade with a nagasa of 68.3 cm and a sori of 1.4 cm, 3.07 cm wide at the base and 2.14 cm at the tip. According to the original seller, the hamon is a gentle notare mixed with midare, and the blade wears a double copper habaki with silver plating. The tang, ubu judging by the photographs, with a single mekugi-ana, is signed 津田近江守助直 (Tsuda Ōmi no Kami Sukenao) and dated 元禄四歳二月日 (Genroku yon-sai nigatsu hi), the second month of 1691. The mounting, which the original seller presents as a period koshirae without dating it, comprises a tsuka of white same with flat light-brown wrapping, copper fuchi-kashira with a crawling dragon in inlaid gold wire, a square iron tsuba, a black saya in ishime finish and a dark brown sageo. The blade comes with NBTHK Tokubetsu Hozon Tōken papers issued in 2014.

The score adds and subtracts points for each feature of the piece and has no ceiling: the highest in the catalogue today is 255. It is computed from the record, not from an opinion. The mounting starts from what is known of its period, adds what vouches for it (its own NBTHK paper, a signed fitting, a crest) and subtracts what has been restored (saya, ito, same, habaki or sageo).
