NihontoWatchShinshinto Musashi Late Edo Saijo-saku Shinogi-zukuri, shinogi is jinjo, iori-mune is low, chu-kissaki is slightly acute and feels extended. Bo-hi on both sides are maru-dome above the habaki. Kitae is ko-itame, somewhat sunken and tight, with areas of hada-tachi, the ji-iro is somewhat blackish, ji-nie attaches well, and the jigane is good. Hamon is angular gunome, ko-gunome, and ko-choji densely packed and overall saka-gakari, the habuchi is nioi-guchi dominant with ko-nie and is tight, within the ha there are ko-ashi and ko-gunome-ashi entering well. Boshi is ko-midare and returns in an o-maru style. Nakago is ubu, the tip is ha-agari kurijiri, yasurime is kesho o-sujikai. Copper with silver-clad habaki. Period polish (small rust present). In shirasaya. Masahide was called Kawabe Gihachiro, born in Kan'en 3, originally from Yamagata in Dewa Province, first used the name Takehide, later Terukuni, and in An'ei 4, he was employed by the Akimoto family, lords of the Yamagata domain, changed his mei to Masahide, and took the go "Suishinshi". In Bunsei 2, he passed the name to the second generation Hakukuma Nyudo and changed his mei to Amahide, and died on September 27, Bunsei 8, at the age of 76. His works range from around the beginning of An'ei to around Bunsei; as for his style, in the early period there are many flamboyant works in the Osaka Shinto style, and after Bunka, based on his own "Fukko Zoho-ron", he transitioned to a calm suguha-style based on practical use. Sadahide was the legitimate son of the first generation Masahide and was called Kumajiro, born in An'ei 8, first used the mei Masahiro, later changed to Sadahide, and took the go "Suikanshi". In Bunsei 2, he succeeded as the second generation Masahide from his father, and when his father changed his mei to Amahide, he himself entered the priesthood and signed as Hakukuma Nyudo. He died young at the age of 47 on October 20 of the same year, less than a month after his father's death. The mei are signed as "Kawabe Sadahide", "Suikanshi Sadahide", "Suishinshi Sadahide", "Suikanshi Hakukuma Nyudo Masahide", "Suishinshi Hakukuma Nyudo Masahide", and so on. This work, as can be seen from its meibun, is a gassaku-to by the first and second generation Suishinshi Masahide, corresponding to the first generation at age 67 and the second generation at age 38. On the nakago omote it says "Suishinshi Masahide Saijin", but "Sai (sai), niragu" is also written as "Sai", meaning to perform the yaki-ire on a sword. Therefore, it is understood that the shitaji and tanren were done by the second generation, and the yaki-ire was performed by the first generation. The nagasa is slightly less than 2 shaku 4 sun 2 bu, and the workmanship with angular gunome densely packed and overall saka-gakari is a blade that put his own "Fukko Zoho-ron" into practice; in particular, this characteristic saw-like ha is a typical work in the style of an "Osafune Kagemitsu" utsushi. By placing many ashi within the ha, the cutting ability and durability are strengthened, resulting in a finish that emphasizes practical use. There are no large kizu, the jiba is kenzen, and the mei is signed by each on the omote and ura. This will be a very precious extant specimen.

Suishinshi Masahide's earliest dated blade, of An'ei 6 (1777), is signed "Gorō Masahide" in homage to Gorō Masamune, and the published sources call that date "the oldest year they have seen"[[c:1]]. He was born Kawabe Gihachirō in Kan'en 3 (1750) at Akayu in Dewa. He first signed Suzuki Takahide and then Eikoku, studied under the Shitahara smith Yoshihide of Musashi, and is said to have entered the school of Sōshū Tsunahiro as well. In An'ei 3 he took the name Masahide and the art name Suishinshi in the service of the Akimoto house of Yamagata, and later he moved to Hamachō in Edo. He trained many pupils and left many writings. His working life ran close to fifty years, from An'ei to Bunsei; in Bunsei 1 or 2, the sources differ, he took the lay name Tenshū, and he died in Bunsei 8 at seventy-six.
He is remembered as the theorist of the revival sword, who held that "all swords should return to the Kamakura of old"[[c:2]]. The published sources are candid that his own best work came before that theory. Through the Tenmei, Kansei and Kyōwa years he modelled himself on the Ōsaka shintō masters, tempering the surging tōran-midare of Tsuda Sukehiro or the suguha of Inoue Shinkai, and "it is rather in this period that his masterpieces are found"[[c:3]]. Over a tightly packed ko-itame that often tightens toward a plain, muji-like surface, thick ji-nie adheres. The tōran builds a large gunome into rolling waves from a long straight yakidashi, with heavy ashi, deep nioi and a bright nioiguchi. His Shinkai manner is a broad suguha deep in nie and nioi, and a few blades follow Ikkanshi Tadatsuna. The finest come so close that the record says they "all but reach the original"[[c:4]], and an early katana is called "an outstanding example of the so-called Ōsaka copy"[[c:5]].
The published sources state with equal precision what still separates him from the originals. His blades tend to scant hiraniku, "giving a flat feeling"[[c:6]], and the point always tends to stretch. His jigane is clean, yet "darkened coarse nie attach to it"[[c:7]] and it comes "close to mekura-gane"[[c:8]], the blind steel in which the hada does not show. Within the ha, too, coarse nie gathers here and there. On an Ikkanshi copy the commentary finds "blackish kazunoko-nie spilling over a muji-like forging, in which his habitual hand is seen"[[c:9]]. On a Sukehiro copy it is "coarse nie that mostly spills from within the ha into the ji"[[c:10]]. The bōshi generally runs straight to a ko-maru.
In his late years he put the theory into practice, and the published sources describe the result as a Bizen-den that is shallow-tempered from first to last, with Sōshū and Mino work also attempted. One late Bizen-den katana tempers a nioi-deki chōji-midare with abundant ashi and a tight, bright nioiguchi, "the chōji tempered without a flaw"[[c:11]], yet with an urumi at the koshimoto that marks his hand; its tang records that his son Sadahide did the forging. Honma's inventory of the Imperial collection follows the change through three dated blades. A katana of Kansei 10, made at forty-eight, "is still a work in the Osaka shintō manner"[[c:12]], a large notare with a bright nioiguchi and thick ko-nie. A wakizashi of Bunsei 1 is unhurried, with especially fine jigane, and the entry wonders whether it copies "Sadamune and the like"[[c:13]]. By Bunsei 2, at seventy, his work is mostly a ko-chōji mixed with gunome, the nioiguchi tight in a ko-nie deki over a muji-like jigane. The carving of these years, the entry adds, is "almost all by his pupil Honjō Yoshitane"[[c:14]].
Between the two phases the judges keep a clear order. Of the Kyōwa 3 katana recognised as a Jūyō Bijutsuhin they write that the later work matters for sword history as a sign of its age, but "in quality the better pieces are rather found among the former"[[c:15]]. Of the revival they say plainly that "his technique did not reach that of his pupil Taikei Naotane"[[c:16]]. His own signature varies: the Kyōwa mei is cut in block script and also in cursive, and he used punning forms of the name. From Kansei 10 he stamped his tangs with a seal of the characters Nichiten worked into a sword shape. Its state of wear and repair dates a blade and helps sort true work from false, and the Bunsei 2 seal is "the last of the five seals of his lifetime"[[c:17]]. Among his pupils the published sources name Taikei Naotane and Hosokawa Morihide, the later second Masayoshi.
Masahide's record is entirely signed: twenty-four Jūyō blades, one prewar Jūyō Bijutsuhin and three blades in Honma's inventory of the Imperial collection, twenty-eight designated works on record. He has no National Treasure and no Important Cultural Property. The Jūyō Bijutsuhin katana, dated Kyōwa 3 (1803), was held by the Shimogō Kyōsaikai of Shiga when it was recognised in 1941. The commentary prizes his daishō, calling them "rare and valuable"[[c:18]], and his blades made jointly with pupils, among them the tenth-generation Sendai Kunikane. Of a katana signed with Hosokawa Morihide it writes that "a joint work by the two is extremely rare and good material"[[c:19]]. Because his work is signed, dated and comparatively numerous, a Masahide is not beyond a private collector's reach. A Jūyō example of his Ōsaka manner comes to market from time to time, and it carries the signed hand of the man who turned Edo swordmaking back toward the old models.

At Hamachō in Edo, in the closing decades of the eighteenth century and the opening ones of the nineteenth, Suishinshi Masahide[[c:1]] gathered the school that would turn Japanese swordmaking back toward its medieval models. Born Kawabe Gihachirō at Akayu in Dewa in 1750, signing first as Suzuki Takahide and then Eikoku, he studied under the Shitahara smith Yoshihide of Musashi, took the name Masahide in An'ei 3, and served the Akimoto house of Yamagata before settling in Edo, where he worked for nearly fifty years. He is the founding figure of the shinshintō and the theorist of the fukko-tō (revival-sword) doctrine, the argument that the sword ought to return to its Kamakura forms. Around that teaching he drew a large body of pupils, among them Taikei Naotane, who would give the revival its fullest practical form, the future second Masayoshi (Hosokawa Morihide), and a wider Edo and provincial following that carried the program into the Mito, Yonezawa, Tsuyama, and Tatebayashi domains. The shared vocabulary of the school is the deliberate reach back into the koto traditions, worked over a tightly forged, often muji-toned ko-itame with thick ji-nie. Masahide's own prime hand was the Ōsaka-utsushi, the surging tōran-midare of Tsuda Sukehiro opening from a long yakidashi and the broad suguha after Inoue Shinkai, betrayed on even his closest copies by a blackish, coarse nie that spills from the ha into the ji. Naotane gave the revival its Bizen and Sōshū faces: a reverse-leaning chōji-midare with angular kaku-gunome and saka-ashi, modeled on the late-Kamakura Osafune masters Kagemitsu and Kanemitsu and anchored by a consciously revived midare-utsuri that no ordinary shinshintō steel carries, set beside a Sōshū notare with its whorled uzumaki-hada and coarse, striped nie. The pupils divided this inheritance along their own lines. Jirōtarō Naokatsu, Naotane's adopted son, took a Bizen-den led by a kataochi-gunome from Kanemitsu with a pervasive saka-gakari slant and chōji- or midare-utsuri in the ji.
Suishinshi Masatsugu reproduced Naotane's two traditions, Sōshū and Bizen, down to the cut of his signature. Through Masayoshi the Bizen current passed to his heir Hosokawa Masamori of Tsuyama, whose chōji clusters mixed with gunome-chōji and togariba. The Osaka wave traveled separately into Mito through Naoe Sukemasa, who set a Shinkai-styled suguha and a Sukehiro tōran over a clear ko-itame, while Chōunsai Tsunatoshi of the Uesugi service carried a nioi-deki chōji mixed with gunome, suguha, and tōran-midare, often with carving by his own hand. To kantei the school is to weigh a tradition consciously copied against the period marks the copy cannot shed: the constant of the line is that the hamon is never the pure nioi-deki of old Bizen but carries nie throughout, a difference the NBTHK names outright as the divide between koto and shinshintō. The revived utsuri in Naotane and Naokatsu, the spilling nie in Masahide, the whorled uzumaki-hada shared across the line, and the broad, thick-kasane late-Edo sugata are the surest tells, narrowed further by the school's habit of full, dated signatures that make these smiths among the most exactly knowable of their age. Masahide stands at the head as the teacher and theorist, his finest work in his Ōsaka copies rather than the doctrine he proclaimed; Naotane stands ahead of him in execution, his Bizen-den held the finest among the shinshintō. Their pupils define the late-Edo Osafune and Sōshū revivals as practiced through Edo and the domains, with Naokatsu and Masatsugu read as the next hands after Naotane and Masayoshi. The provenance of the school runs through domain commission and bestowal (Mito blades forged at the Kōrakuen by lordly order, Tsuyama and Yonezawa fief work, Naotane's Sanada daishō and a tachi recorded in Honma's inventory of the Imperial collection) rather than ancient daimyō transmission, fitting for a movement that, within a single generation at Edo, redrew the direction of nineteenth-century swordmaking by turning it back toward the old models.

The Shinshintō revival
Around 1800 Suishinshi Masahide argued in his writings that the craft must return to the old masters’ methods: the fukkotō revival. His greatest successor Naotane worked convincingly in Bizen and Sōshū manners that had been dead for centuries.
