The piece

Katana by Tsushima no Kami Tsunemitsu of the Edo Ishidō school, dated 1661, designated Jūyō Tōken by the NBTHK at the 22nd session, with a gold-lacquered koshirae and shirasaya.

Tsushima no Kami Tsunemitsu was, together with Dewa no Kami Mitsuhira, one of the leading smiths of the Ishidō branch established in Edo, Musashi province, known for chōji midare reminiscent of Ichimonji work. The blade is shinogi-zukuri with an iori-mune, shallow sori and a somewhat compact chū-kissaki, with a bōhi ending in a rounded maru-dome on both sides, visible in the photographs. According to the NBTHK assessment, the jigane is a dense ko-itame with midare-utsuri, and the hamon a chōji midare mixed with ko-chōji and ko-gunome, with abundant ashi and yō and a bright nioiguchi; the original seller also notes jūka-chōji. The tang is ubu with a single mekugi-ana, signed 対馬守橘常光 (Tsushima no Kami Tachibana Tsunemitsu) on the omote and dated 寛文元年八月日 (Kanbun gannen hachigatsu hi) on the ura. It was designated Jūyō Tōken at the 22nd NBTHK session on 1 June 1974; the assessment regards it as a valuable reference for its date. It comes with a koshirae featuring a gold nashiji lacquered saya with family crests, an iron tsuba with gold inlay and a wrapped tsuka, as well as its shirasaya.

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).
