Sukekane (助包) is a name borne by multiple smiths recorded in the swordsmith compendia under both the Ko-Bizen lineage and the Fukuoka Ichimonji lineage, active from the late Heian period through the early Kamakura period in Bizen province. The reference works list several distinct craftsmen using this signature, and moreover several different styles of writing the signature characters are known. Broadly speaking, Ko-Bizen examples bear comparatively small signatures and tend toward nie-based workmanship with tasteful small irregular tempering, whereas Ichimonji works generally show larger signatures and exhibit flamboyant chōji-based midareba in which a sense of technical artifice is felt. Conventionally, small and intermediate-size signatures have been assigned to the Ko-Bizen group, and large signatures to the Ichimonji group; however, as the NBTHK has observed, even among works appraised as Ichimonji there are examples with small signatures, and therefore a distinction based solely on the style and size of the signature is not necessarily easy. The name is also closely associated with Suketsugu (助次), another Ko-Bizen smith whose intermediate-style signatures represent the oldest stratum of this school.

The characteristic technical manner of Ko-Bizen Sukekane is anchored in a forging of itame-hada mixed with mokume, frequently showing a tendency toward standing grain, with ji-nie adhering thickly and chikei entering well. Midare-utsuri — and in certain works jifu-utsuri — stands out distinctly across the ji. The hamon is typically based on ko-gunome or a suguha-toned composition, into which ko-notare, ko-chōji, and ko-midare are mixed; ko-ashi and yō enter profusely, and ko-nie adheres well. A hallmark of the upper portion of many blades is the intermittent appearance of nijūba and sanjūba running along the cutting edge. Internal activities are abundant: kinsuji and sunagashi appear throughout, and in some works fine tobiyaki and yubashiri are interspersed. The nioiguchi is consistently described as bright and clear. The bōshi tends toward sugu with ko-maru turnback, frequently accompanied by hakikake. Even within Ko-Bizen work, certain blades by Sukekane are noted for their broad and firmly constructed form, with thick ji-nie and chikei frequently active throughout, while others present a more slender, archaic silhouette with ko-kissaki and pronounced koshizori preserving an old-style tachi sugata.

The NBTHK repeatedly characterizes Sukekane's oeuvre as manifesting an archaic, old-scented workmanship characteristic of Ko-Bizen work — a refined and classical manner in which both ji and ha carry a savory depth of taste. Because extant works by this smith are few, designated blades are recognized as possessing exceptionally high documentary value for understanding his working range, signature forms, and the breadth of his craftsmanship. Works are praised as kenzen — sound and well-preserved — with excellent appearance, and the finest examples are assessed as superior and highly accomplished achievements. Certain blades carry distinguished provenance, including transmission within the Satake family of Akita during the domain-government era, and gold-inlaid attributions by Hon'ami Kōson. Sukekane occupies a position of particular scholarly importance within the Ko-Bizen canon: a smith whose small surviving corpus, combined with the difficulty of separating his hand from that of the Ichimonji-line bearers of the same name, renders each authenticated work an indispensable reference for the study of early Bizen tradition.
