This katana is a collaborative work by the 2nd and 3rd generations of Nobutaka, a master smith from Owari province, known as one of the "Owari Sansaku." It features a robust construction with a slightly thick kasane and an extended chu-kissaki. The jigane is ko-itame with ji-nie, and the hamon is a vibrant gunome-midare with small choji and yahazu-style patterns, showing strong nie and sunagashi.

The San'ami line takes its root in Mino Province, where its head smith Kanenori (兼則) worked as one of the so-called Seki Seven Schools. The setsumei place Kanenori from the close of the Nanbokuchō period into the Ōei era of the early Muromachi, alongside Kanemoto and Kanesada among the representative hands of Sue-Seki, and the earliest extant signed tachi of his is appraised as no later than Ōei. A second early smith, Kanekuni (兼国), is recorded as belonging to the San'ami lineage and is judged to predate the Sue-Seki group proper; the remote ancestry given for him runs variously to a disciple of Naoe Kanetomo, to Yamato Kanekuni, or to Kanenori, though the setsumei note that nothing survives to confirm so distant a descent. From this Mino stock came Hōki no Kami Fujiwara Nobutaka (信高), born at Kami-Ōchi in Mino in 1563 and said to descend from San'ami Kanekuni. After receiving the title Hōki no Kami in Tenshō 9 (1581) he moved to Kiyosu in Owari and, serving Tokugawa Yoshinao, later settled at Nagoya, carrying the line into the early Shintō era through a second generation who took the tonsure in Kanbun 2 (1662). Across the corpus the jigane is itame, often closely forged and tending to nagare-hada or flowing grain along the edge, with ji-nie and a frequent standing of the grain (hada-dachi); a faint whitish cast (shirake) marks the older Mino work of Kanenori and Kanekuni. The temper rests on suguha as a base. In the early hands it is a tight, clear (saete) suguha in nioi-deki, sometimes mixed with small gunome, angular elements and pointed ha, carrying ashi, hotsure and scattered tobiyaki.
The Nobutaka works open this out: a broad suguha shifting to shallow notare, ko-notare with a gunome-flavored edge, deep nioi with nie unevenly applied and partly coarse, nie-kuzure at the yakigashira, kuichigai-ba, kinsuji, sunagashi, yubashiri and tobiyaki that climb into the shinogi-ji until the upper half reads as hitatsura. The bōshi runs to sugu with ko-maru, at times midare-komi, pointed, or hakikake, and the early swords keep a slender, high-sori tachi shape while Nobutaka's carry the wide-bodied, ō-kissaki form of the Momoyama transition. The hand is recognized in this pairing of a flowing Mino itame with a suguha core that, in the descendants, breaks toward bold hitatsura. For kantei, the setsumei fix several anchors. In Kanenori's signature the scooped chisel at the fourth stroke of the character kane (兼) is read as a trait of late Nanbokuchō through Ōei work, matched in dated Kaneyoshi mei; the clear suguha of Kanekuni is likened to a Zenjō Kaneyoshi masterpiece. The jizō-flavored bōshi and the nagare-mixed itame in Nobutaka are named as the surviving stamp of the Mino root beneath his Owari manner, and one of his katana is recorded as an Inabae-utsushi. Provenance runs through the corpus: a Kanekuni bears kinzōgan recording it as the sashiryō of Ōkubo Genban-no-jō Tadanari, lord of Odawara in Sagami, worn at the age of ninety-three; Kanenori's tachi descended in the Yamanouchi family. Among the Owari yari makers beginning with Masatsune, Nobutaka's yari of extraordinary length is held in particular regard, and the second-generation Nobutaka is judged no less skilled than his father, with the finest extant Nobutaka works counted to his hand.

The Edo period (1615 to 1868)
Under the Tokugawa peace the daishō became a regulated uniform, and demand gathered in the castle towns, above all Edo itself. The craft split two ways: brilliant display work for connoisseurs, and tested blades whose cutting results were sometimes inlaid in gold.
A Hozon-certified blade judged to show notably superior workmanship and a better state of preservation. The bar is higher: re-tempered blades and most unsigned Muromachi/Edo works are excluded.
The NBTHK (Nihon Bijutsu Tōken Hozon Kyōkai, the Society for the Preservation of Japanese Art Swords) is a public-interest incorporated foundation founded in 1948 and supervised by Japan’s Agency for Cultural Affairs (Bunkachō); it is based at the Japanese Sword Museum in Tokyo. Its expert panels physically examine each submitted work (shinsa) and issue a certificate (kanteishō) ranking it by artistic and historical merit. NBTHK papers are the most widely recognized standard of authentication for Japanese swords and fittings.
