Edo was the sword’s age of connoisseurship: the Hon’ami appraisers, the shogunal register of famous blades of 1719, and a thriving literature turned the sword into an object of study even as it ceased to be drawn in war.
This is a Shin-Shinto katana signed by Naganobu, dated February 14, 1860. The blade features a fine ko-nuka hada and gunome hamon, accompanied by a Tokubetsu Kicho paper from the NBTHK. It comes with a well-made koshirae including an iron tsuba, shakudo fuchi with copper moth, and shakudo menuki with gold and silver inlay.

The Unshū grouping gathers smiths of Izumo province (Unshū), and the blades carrying this attribution do not form one continuous lineage so much as two widely separated moments in the province's work. The earlier is Unshū Tadazane, a signed katana placed around the Eishō era (1504 to 1521) in the late Muromachi period. The later is Takahashi Naganobu, also recorded as Unshū Naganobu and Takahashi Rihei, a late-Edo smith dated by his own inscriptions to Ansei 3 (1856) and Man'en 1 (1860). Naganobu styled himself the seventeenth-generation successor of Wakasa Fuyuhiro; around the close of the Tenpō era he went to Edo and studied under Chōunsai Tsunatoshi, and after gaining recognition he served as a retained smith (kakae-kō) of the Matsudaira house of Matsue in Unshū until his death in Meiji 12 (1879). Because the two hands belong to different centuries and different stylistic worlds, the group reads as a provincial wakimono gathering rather than a school of fixed transmission. Across these blades the shared ground is a tightly forged ko-itame-hada with ji-nie adhering, after which the two hands diverge. Tadazane's ko-itame packs closely and flows toward the edge with masame mixed in, carrying a wide suguha mingled with small gunome, ashi and yō entering well, ko-nie and sunagashi, and a subdued (shizumi) nioiguchi; his bōshi runs straight to ko-maru with a long kaeri, and the overall effect was read by the NBTHK as sharing features with the Bizen smiths Kiyomitsu and Tadamitsu.
Naganobu instead builds bold, long sugata of wide mihaba with little taper, his ko-itame often taking on an almost plain (muji) look with abundant chikei. His preferred temper is neatly aligned chōji mixed with gunome in nioi-deki, though one of his katana hardens a flamboyant gunome-midare of round heads with a deep, bright nioiguchi and yubashiri. The most reliable signpost to his hand lies in the nakago: reverse ō-sujikai filemarks with keshō, named in the setsumei as a characteristic feature. For kantei the group resolves to its named smiths rather than a collective signature. Tadazane is recognized by his Bizen-leaning suguha-gunome and subdued nioiguchi, his example preserved with a Higo-style shuhen-nuri handachi koshirae. Naganobu is identified through his reverse ō-sujikai tang finishing, his Tsunatoshi-derived chōji, and on occasion a vigorous midare whose assertive spirit the setsumei likens to superior works of the Yamaura lineage; his commissioned blade names Tomono Shigenari of the Matsujō domain and records its making at Kōji Street in the eastern capital. The standing of the group rests on these two distinct workmanships, each documented within the records of its own province. Learn more →

This work carries older NBTHK “Kichō”-era papers, which the NBTHK no longer issues and now regards as unreliable. To confirm the attribution, submission to an official Japanese examination body (such as the NBTHK or NTHK) for modern certification could be considered.
