Sukekane is a swordsmith of the late to early period, his name one of the school's enduring puzzles. Two Jūyō-Bijutsuhin designated in 1935, one signed in six characters " no Sukekane " and held by the Matsudaira house, the other a small-signature blade from the Sakai house, fix him in the historical record; the published sources note that the name Sukekane is found among both the group and the Fukuoka line, and that there were likely three or four smiths who shared it. The man profiled here is the one, the archaic hand. The published commentary draws the distinction plainly: of the two Sukekane, "the former is an archaic, classical small- of -based workmanship, whereas the latter forges flamboyant chōji-based in which a sense of technical artifice is felt" (前者が沸出来の古雅な小乱の出来であるのに対して後者は丁子の華やかな乱刃を焼き技巧味が感ぜられる). His is the quiet side of the divide.
His characteristic temper is a -toned small . Over it run , and , with and entering well, the work -based, with and fine coursing through and, on a recurring group, and even sanjūba running intermittently along the upper edge. This is not the regular clove-flower of the smiths but the calm, antique line the published sources call the manner of old , where "flamboyant is uncommon" (総じて華やかに乱れるものは少なく) and "a -toned base with shallow predominates" (直刃調が浅いのたれを基調とする). The answers the edge below it, running straight to a or finishing in a -like sweep with , sometimes with drifting at the turn.
The is the constant. He forges a well-packed mixed with , the grain standing a little, with and entering frequently, and a clear rising in the . On the finest of them the reflection thickens into the patchy of old steel. Over that the is bright and clear, and the carries thick . The published sources prize exactly this antique flavor, calling one a work of "old-scented workmanship characteristic of " (古備前物としての古香な出来口), the and carrying a savory depth of taste.
Within his own record the work divides into two registers of one hand. The typical Sukekane is a slender , where it survives so or shortened yet keeping a high with , the point a compact , the temper a calm -toned . On his outstanding signed the line opens out: a broad into which , and angular elements are set, flowering into a brilliant that the judges single out, one such piece called "a particularly outstanding achievement" that strikingly manifests the features of . The signature is its own scholarly question. The published commentary records small, intermediate and large hands, and notes that while the convention treats small signatures as and large ones as , some works carry small signatures too, so that "a distinction based on the signature alone is not necessarily easy" (銘振りからは、必ずしもその区別は容易とはいえない).
What sets the Sukekane apart from his namesake is exactly this -based restraint. His bright , his -toned small with its and deep , and the archaic, slightly drooping shape with its are read as , while the flamboyant and the air of technical display belong to the other hand. On the and attributed to him, the published sources affirm the appraisal from the period and the workmanship rather than from any single personal tell, accepting the traditional attribution where the and are markedly archaic in tone. His blades stand at the root of the line, before the school's great flowering at Fukuoka.
For the collector he is a rare early name. Fujishiro grades him Jō-jō , and the Tōkō Taikan values his work near the top of its scale. He has no National Treasure of his own hand; his record runs instead through the Important Cultural Property rank and the prewar Jūyō-Bijutsuhin, with two blades in the and twenty-two in the . Because his extant works are so few, the published sources call his best signed documentary material of very high value for understanding him at all. His blades carry distinguished provenance, transmitted in the domain era through the Satake house of Akita, the Tokugawa and Matsudaira families, the Sakai house of Tadakatsu, the Ikeda of Inshū, and bearing in one case the gold-inlaid ownership name of Takeda Genshinren. Most are long held, not traded; only the and tier ever moves, and even then a signed Sukekane comes to light only seldom. A privately held example, of recorded whereabouts, is a notable thing for a collector to encounter, a document of how began.
