NihontoWatchNihontoWatchBlade construction: Shinogi-zukuri with an Iorimune. The blade measures an impressive 2 shaku 5 sun 2 bu (approximately 76.4 cm), featuring a shallow curve leading to a medium-sized Kissaki (tip). The base of the blade is wide that shows standing firmly on base and considerable thickness that gives it a substantial, heavy feel in both hands. The overall construction reflects the style prevalent around the Kanbun era (1661–1673). Forging pattern: The steel on the Shinogi-ji is forged in a straight grain pattern (masame), while the Hiraji displays a tight ko-Itame (small wood grain) texture, densely covered with sparkling Ji-nie (crystalline martensite particles). Hamon: Starting with a long Kyo-yakidashi (Kyoto-style gradual temper start), the hamon features a high, undulating pattern incorporating Gunome (wavy peaks), Chōji (clove-shaped patterns), Togari-ba (pointed peaks), and Yahazu-ba (arrow-notch shapes). This creates striking modulation and variation, with bright, vivid Nie on boundary lines. Thick Ashi (Nie legs) radiate toward the tip, with Kinsuji (thick lines) and Sunagashi (sweeping streaks of Nie), resulting in a clear and beautiful Hamon. Bōshi (tip temper): The pattern becomes gently wavy and finishes in a medium round (Chu-maru). Tang (Nakago): In its original, unaltered state (ubu Nakago), with file marks (Yasurime) slanting downward left (Katte-sagari). One Mekugi-ana (peg hole). The Nakago-jiri (heel of the tang) is a Kuri-jiri shape, slightly turned toward the edge (Ha-agari). The back of the nakago is flat, with file marks also in Katte-sagari style. On the Shinogi-suji line below the Mekugi-ana, there is a long signature deeply chiseled with thick strokes and prominent tagane-makura (chisel ridges) reading: "Echizen no Kami Minamoto Sadamichi" 越前守源定道. "Echizen no Kami Minamoto Sadamichi" 越前守源定道 said the same smith known as "Sadatosh" 定俊. Originally from Mino Province, he was a descendant of San'ami Kanenori 三阿弥兼則 and became a disciple of Iga no Kami Kinmichi 伊賀守金道 in Kyoto, later receiving the honorary title "Echizen no Kami" 越前守. He signed his works as "Mishina Echizen no Kami Minamoto Sadamichi" 三品越前守源定道 or "Echizen no Kami Minamoto Sadamichi" 越前守源定道. It is said that he established his forging studio near Nagoya Castle and was active from the Kanbun to Tenna eras (1661–83). The subject katana, made specially on a particular commission from an Owari warrior who deeply honored martial spirits is especially long, thick and has a heavy, powerful presence. The elegant hamon, which begins with a Kyoto Yakidashi and flows with graceful modulation, captivates the viewers, affirming his belonging to the Mishina school in Kyoto. The blade retains a vigorous, well-preserved shape and volume and the Nakago has developed an attractive patina of age more than 350 years. Comes with a gold-foiled single-layer Habaki and preserved in a plain wooden Shirasaya scabbard. Recent good polish/Condition scale: excellent (using a scale of mint-excellent-very good-good-fair-poor).

The Mishina school (三品), one of the two dominant smithing groups of early Edo Kyoto beside the Horikawa, grew from the late-Mino workshop of Kanemichi of Seki, whose dated blades run through the Tenbun, Eiroku, and Tenshō eras. During the closing decades of the sixteenth century Kanemichi came up to the capital with his four sons and settled at Nishinotōin Ebisugawa, where the eldest, Iga no Kami Kinmichi, is recorded as having greatly raised the name of the line. The brothers, Kinmichi together with Izumi no Kami Rai Kinmichi, Tanba no Kami Yoshimichi, and Etchū no Kami Masatoshi, became known collectively as the Sanpin (三品) makers, and the published sources count Kinmichi head of the Kyō go-kaji, the five Kyoto smiths. From the second generation the house held a hereditary right to recommend smiths to the court for their titles and added that by-line to its signatures. The name continued under the same appellation to the end of the Tokugawa period, throwing off branches that included the Tango no Kami line working at Ōsaka into the Genroku years, though the published record consistently holds the founding generation the most outstanding of the line. Beneath every branch lies a shared vocabulary carried up from Mino-Seki. The jigane is the constant: an itame mixed with mokume that flows into nagare-hada and tends toward masame near the mune, the grain standing, with thick fine ji-nie and frequent chikei. Over it the Mino-derived gunome and togariba are refined toward a Kyoto manner, the nie strong and at times coarse, gathering unevenly, kinsuji and vigorous striped sunagashi running throughout. Two tells bind the house. The first is the Mishina bōshi, a notare or midare run-in pointed at the tip and swept with vigorous hakikake, the form Masatoshi shows at its clearest, described as if drawn from a picture. The second is sudareba, the bamboo-blind temper in which layered sunagashi and yubashiri stripe into parallel bands; Tanba no Kami Yoshimichi devised it, and the first-generation hand keeps it a free, semi-cursive disorder where his heirs would regularize it into a fixed lattice.
The lines diverge from that common ground. Kinmichi and his younger brother Masatoshi both excelled in a Shizu manner, the large midare of Mino grafted onto Sōshū nie, with Masatoshi the most versatile, ranging across Shizu, Mino sanbon-sugi, Yamato suguha, and Sōshū hitatsura. The later Ōsaka Tanba branch held to the sudareba alone, opening from a straight yakidashi, while the second Tango no Kami Kanemichi cast off the family chōji for a flamboyant tōran-style large gunome in alternating two-joined and three-joined groups, and a deep-nioi suguha read in the manner of Inoue Shinkai. To kantei Mishina is to read these two house marks first. The pointed, hakikake-swept bōshi and the striped sudareba, set over a standing itame that flows to masame, place a blade within the line before any signature is weighed; the sunagashi, far heavier than on a Bizen ji, is the very material from which the temper is built. Within the house the founding generation sets the standard. Fujishiro grades Kinmichi and Masatoshi Jō-jō saku, the Ōsaka Tanba shodai Jō-saku, and the second Tango no Kami Chū-jō saku, the sources judging the later Kyoto and Ōsaka generations markedly inferior to the founders as the manner thinned toward a single uniform pattern. Provenance on record runs through samurai and collector hands rather than great museums: a Kinmichi katana among the cherished swords of Tani Tateki, a Yoshimichi katana made for Naitō Kuroemon and another now in the Kyoto National Museum, Masatoshi blades passing through Oda Urakusai and the Imperial household, and a second Tango no Kami katana descending from the Aoyama wardens of Ōsaka castle. The brothers' blades are signed and knowable, dated examples rare, so the manner of the mei joins the workmanship in placing them; for the Ōsaka and Kyoto branches the cut of the character 守 separates one hand from the next. Most designated work is held rather than traded, so a signed founding-generation Mishina blade comes to light only from time to time, and with it the temper in which one of the most recognizable hamon of the Shintō era was first being worked out.

Kyōto: the revival workshop
The Shintō era was largely invented in Kyōto: Umetada Myōju’s workshop trained the movement, Horikawa Kunihiro raised a generation, and the Hon’ami appraisers, who held no forge, governed the meaning of famous blades.
Certifies a genuine blade worth preserving: a signature confirmed correct, or, if unsigned, an era, province, and school that the NBTHK can reliably identify.
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.
