The piece

Shinshintō katana from Satsuma, signed by Hōki no Kami Masayuki and dated 1799, with an ubu tang, NBTHK Tokubetsu Hozon paper, shirasaya with sayagaki and koshirae.

Katana by Hōki no Kami Masayuki (also read Masayoshi), one of the leading smiths of Satsuma in the shinshintō period. According to the original seller, he was an official smith to the Shimazu clan, received the title Hōki no Kami in 1789 and, together with Motohira, is regarded as one of the two summits of Satsuma swordmaking. The blade, in shinogi-zukuri with an iori-mune, has a nagasa of 70.9 cm and a sori of 1.5 cm. According to the original seller, the jihada is itame with areas of mokume, Satsuma-gane and abundant ji-nie, and the hamon is a notare-midare in nie-deki with inazuma and imozuru, a hallmark of the school; the photographs show the notare-midare along the blade. The tang is ubu, with two mekugi-ana, signed 伯耆守平朝臣正幸 (Hōki no Kami Taira no Ason Masayuki) and dated 寛政十一年未二月 (Kansei jūichi-nen hitsuji nigatsu), that is, 1799. It holds an NBTHK Tokubetsu Hozon Tōken paper issued in 2024. It comes with a shirasaya bearing an ink sayagaki and a koshirae with a black-lacquered saya, iron tsuba and a tsuka with same and green wrapping.

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).
