The piece
Shinshintō blade from Edo, signed and dated 1846 by one of the leading names of the period, mounted in a koshirae with an unusually shaped iron tsuba. NBTHK Tokubetsu Hozon.
Katana by Chōunsai Tsunatoshi, one of the leading names of the shinshintō period, active in Edo. The blade is signed and dated 1846, so it carries the date cut by the smith himself. It measures 71.2 cm nagasa with 2 cm sori, a pronounced curvature for a blade of its period. It is sold mounted in a koshirae with an unusually shaped iron tsuba with a raised rim, fuchi-kashira bearing phoenixes, flower-cart menuki and a black-lacquered saya. The original listing includes a complete oshigata of the blade, useful for reading the tang and the temper before seeing it in person. NBTHK Tokubetsu Hozon papers are included.

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).
