On the omote of a katana dated Shoho 3 (1646), eighth month, cut on the shinogi-suji in a large, bold five-character hand and joined on the reverse by a gold-inlaid cutting test, stands the earliest dated work that survives from Heki Mitsuhira, the Tokubetsu Juyo blade the published sources call the most retrograde of his dated pieces and a resource of exceptional value for the study of him. Mitsuhira signed Minamoto Mitsuhira, and sometimes Heki Dewa-no-kami Minamoto Mitsuhira beneath a chrysanthemum crest; he was born in Gamo district of Omi[[c:1]], eldest son of Yamashiro-no-kami Ippo of the Kyo-Ishido line, and first styled himself Heki Shichirobei. He stands, the NBTHK states plainly, as one of the most outstandingly skilled smiths who represent the Edo Ishido[[c:2]], the equal and senior of Tsushima-no-kami Tsunemitsu and one of the two pillars of that school. His program was a revival: to forge again, in the bright nioi of the early-Edo workshops, the gorgeous choji-midare of the old Bizen Fukuoka-Ichimonji that the medieval makers had carried over a midare-utsuri jigane.
The feature that names his work is the choji-midare itself, and the published sources read it as his forte. He tempers it chiefly in nioi, mixing many kinds of teeth into one lively, crowded line: gunome and ko-gunome, round-topped choji and small choji, angular elements and others tending to a point. The yakiba rises and falls in marked height, ashi and yo enter vigorously, and the nioiguchi runs bright and clear. The result is what the institution calls a splendid choji-midare that recalls the old Ichimonji[[c:3]], and across his blades the NBTHK names the achievement the same way each time, a piece in which he privately emulated the old Ichimonji and succeeded[[c:4]]. On his most florid katana small tobiyaki gather at the heads of the temper and fine sunagashi is drawn through it, touches the sources read as lending an antique flavor to the otherwise new-sword brightness.
The jigane beneath that temper is what carries the Ichimonji comparison the rest of the way. He forges a ko-itame or an itame mixed with mokume and flowing hada, tightly worked, with the ji-nie gathered dust-fine, and over it stands a clear midare-utsuri, the koto-Bizen reflection that almost no other Edo hand reaches with such conviction. It is the single feature of the jigane that most marks his revival, the old reflection raised again on a shinto blade, and the published sources note it as prominent on piece after piece. The boshi answers the flamboyance of the ha quietly, running straight or in a small midare into a ko-maru, turning back shallowly, often with a touch of hakikake at the point. Ji and ha alike are described as sound, the steel bright rather than dark, the whole reading as Bizen seen through the cleaner light of the Kanbun forges.
Mitsuhira is best understood not through dated periods, since his dated blades are few, but as one perfected manner read at two intensities and set on the build of his age. The constant is the choji-midare over its utsuri; the variation is the nioiguchi. On his finest pieces the published sources mark a tightening and a further brightening, writing of the Tokubetsu Juyo katana that, in comparison with his usual works, the nioiguchi is somewhat tighter and shines with a particularly bright clarity[[c:5]], and that even among his oeuvre it shows an exceptional sharpness of effect[[c:6]]. His blades carry the broad body, the thick kasane and the contracted chu-kissaki of the Kanbun era, yet the sources read the silhouette carefully as a transitional one: at a glance it recalls the Kanbun-shinto shape, but the sori stands somewhat more and a touch of funbari remains at the base, a transitional shape in the shift from Keicho-shinto toward Kanbun-shinto[[c:7]] common to the smiths of the Kan'ei and Shoho years. He signs a long mei of distinctive script in bold, thick chisel strokes on the ubu nakago, sometimes under the chrysanthemum crest with his titles Dewa-no-kami and Dewa-nyudo Taishin hokkyo.
What sets him apart within his own school is finally a matter of the signature, and the published sources make the point through the very biography they repeat. By the common account Mitsuhira moved from Omi to Edo alongside Tsunemitsu, Echizen-no-kami Munehiro and the first Ishido Korekazu, but the NBTHK corrects both the route and the kinship from surviving inscriptions. The Akasaka-signed blades show that the Edo Ishido smiths went first from Omi to Kyoto and only afterward on to Edo rather than directly; and the old tradition that Mitsuhira was Tsunemitsu's younger brother is set aside, since dated pieces worked back show that he was in fact six years the elder[[c:8]]. He used the Minamoto surname while Tsunemitsu used Tachibana, and for that reason, though their workmanship is granted to share much, the brotherhood is doubted. The two are thus the twin masters of the Edo Ishido whose hands run close and whose names part only at the mei, and it is in Mitsuhira's that the Ichimonji revival is reckoned to have succeeded most fully.
Mitsuhira's record on the official rolls is concentrated and high in quality rather than large: of his designated works ten stand in the Tokubetsu Juyo and Juyo tiers, the single Tokubetsu Juyo being the Shoho 3 katana with its gold-inlaid three-body cutting test, the rest Juyo. His designations rise no higher than these, and his blades enter the records signed, every one of them, so that his oeuvre is an open book read off the long mei rather than a body of mumei attributions. Fujishiro rates him Jo-jo saku, the upper-superior grade. The provenance recorded on these blades is thin, with no daimyo house or museum named in their own data, and what survives of him is held quietly in private and public hands. For the collector this is a smith encountered from time to time rather than freely: a designated Edo Ishido katana of his comes to market only now and again, a landmark when one does, prized as the high point of the school's Ichimonji revival and recognized at sight by the bright choji-midare standing over its old-Bizen utsuri.

The Edo Ishido school (江戸石堂) is the capital branch of the Ishido lineage, a body of shinto-era smiths who carried the Bizen choji tradition into Edo and there pursued a single deliberate project: the revival, in the brighter steel of the early-Edo forges, of the flamboyant choji-midare worked by the medieval Fukuoka-Ichimonji masters of Bizen. The school's makers came up from Omi by way of Kyoto rather than directly, the Akasaka-signed blades of Mitsuhira fixing that route, and several of its leading hands trace to the Kyo-Ishido line before the move to the capital; Heki Mitsuhira, eldest son of Yamashiro-no-kami Ippo, and Tsushima-no-kami Tsunemitsu stand as the twin pillars of the early school, while the Edo Ishido Korekazu line carried the house specialty forward, the seventh-generation Korekazu keeping it alive through the nineteenth-century shinshinto revival. A separate Edo strand runs through Yamato-no-kami Yasusada, whom recent research and the Shinto Bengi place within the Kishu Ishido group, a Kanbun-era master of the capital whose temper turns toward the angular rather than the choji of his school-fellows. What binds the school is a shared vocabulary rather than a single hand. The defining work is the choji-midare tempered over a bright shinto ko-itame, a crowded line mixing gunome, ko-gunome, round-topped choji and small choji with angular and pointed elements, the yakiba rising and falling in marked height, the ashi and yo entering vigorously, the nioiguchi clear; on the most successful pieces a midare-utsuri stands in the jigane, the koto-Bizen reflection raised again on a shinto blade, the single feature that carries the Ichimonji comparison furthest. Mitsuhira tempers this revival chiefly in nioi, and the NBTHK reads his choji over its utsuri as the fullest realization of the school's program, a splendid choji-midare that recalls the old Ichimonji. Korekazu departs precisely here: where the other Bizen-leaning smiths held their choji in nioi-deki, he forged the house pattern in nie-deki, deep in nioi and thick in nie over a ko-itame approaching a muji-fu tightness, with sunagashi, kinsuji and nie-suji threading the edge, a Bizen pattern carried on a Soshu-leaning base.
Yasusada marks the school's outer divergence, working a notare mixed with gunome that boxes at peak and valley, the nioiguchi inclining to a subdued shizumi and a steeply raised iori-mune among his marks, his Soshu-leaning nie temper inherited through Kaneshige. Across all of them the jigane is the constant that underwrites the edge, a densely forged ko-itame, sometimes mixed with mokume, the ji-nie laid dust-fine and chikei entering well. To kantei an Edo Ishido blade is to read a revived Bizen choji set on an unmistakably shinto ji: the choji-midare draws the eye to old Ichimonji, but the steel beneath is the bright, clean forging of the Kanbun and later forges, frequently on the broad body, thick kasane and contracted chu-kissaki of the era, with Mitsuhira's transitional silhouette retaining a touch of funbari and standing sori. The utsuri when present confirms the school's intent; the choice of nie-deki over nioi-deki separates Korekazu from his fellows; the boxed notare and shizumi nioiguchi mark out Yasusada, whose hand is read against Kotetsu rather than against his school. The NBTHK ranks the best of these makers among the leading smiths of their respective ages, Mitsuhira as one of the most skilled to represent the Edo Ishido and Korekazu beside Jirotaro Naokatsu and Hosokawa Masayoshi among the late-Edo masters. Provenance is generally quiet, held in private and public hands rather than great houses, though the school's blades carry the texture of their moment: the Yamano gold-inlaid cutting-test inscriptions recur on Yasusada and on Mitsuhira's earliest dated work, one Korekazu blade is held by the Imperial Family, and his man'yogana and joi-slogan inscriptions voice the late-Edo current that the school's final flowering of Bizen-den outlived.
