Sukekane of province is a name the published sources approach as one of the school's standing problems, and the surviving record that anchors him is the signed, unaltered designated in 2024, a blade preserved in the form it had at manufacture. He worked in the middle period within Fukuoka , the school descending from Norimune. The difficulty the published sources keep returning to is the name itself: the records a Sukekane under both , dated about the Genryaku era, and , dated about the Jōei era, and one account holds the signature comes in as many as five distinct patterns. Most surviving signatures are the two characters 助包; only a very small number of long inscriptions reading " no Sukekane " are confirmed. The conventional view assigns the small-character hand to and the large-character hand to , "the small signature taken as and the large hand as " (「小振りの銘を古備前、大振りの手を一文字としている」), but the sources state that this division "is not necessarily easy from the calligraphy and the manner of the signature, and requires careful scrutiny" (「書体などの銘振りからはその区分は必ずしも容易ではなく精査が必要である」), since a separate small- Sukekane, transmitted in the Inshū Ikeda family, is itself judged and carries the national-treasure designation (国宝) the sources cite.
The hand the sources single out as quintessentially his belongs to those signed , and it is a flamboyant one. Over a well-packed jigane he sets a temper that runs high from base to tip, chōji the principal tone, mixed with ko-gunome, gunome and pointed togariba, the ashi and yō entering well. The published commentary on the Tokubetsu Jūyōtachi writes that what especially draws the eye is its high, "flamboyant chōji-midare" (「華やかな丁子乱れ」3) reaching from the base through the monouchi, the composition richly varied through clusters of differing size. The nioiguchi is laid with ko-nie gathering unevenly, and around the koshimoto and monouchi a yubashiri-like effect runs in the edge. The same sources place this flamboyance beside the small-mei Sukekane judged 国宝 and say it "expresses to the fullest the essential appeal of chōji-midare" (「丁子乱れの醍醐味を遺憾なく示し」4). It is the showy Fukuoka manner held at full height, the opposite pole from his schoolmate Yoshimochi, whose hand the published record treats as the deliberately quiet one.
The jigane beneath that temper is as much a part of his recognition as the hamon. The forging on the signed tachi is a refined ko-itame, densely packed, with ji-nie applied, and from the machi a mizukage rises; above it patches of dark band become jifu, settling into a clear midare-utsuri. This rich Ichimonjimidare-utsuri is the one trait that crosses every part of his record, standing as plainly on the ō-suriagemumeikatana as on the signed tachi, and the published sources note it on blade after blade. On the slender, shortened tachi held in the Mōri and Tokugawa houses the jigane is a well-packed itame with ji-nie and chikei, the same Fukuoka ji in a quieter register. The bōshi of the prime tachi is deeply tempered, almost a single sweep, running straight to a yakizume-toned point with hakikake and a long turnback, which the sources read as further evidence that it keeps nearly its original form. At the koshimoto he carves bonji with a sankō-tsuka-ken on one face and bonji with gomabashi on the other; the published commentary calls these later additions that nonetheless do not detract from the appearance and rather set off the blade.
His record divides cleanly into two faces. The first is the ubu, two-character signed tachi just described, standard in width with the taper slight, koshizori high with curvature added toward the point, a chū-kissaki: the recognized prime, of which only a few survive, several papered to the Tokubetsu Jūyō and Jūyō ranks and to the prewar Jūyō Bijutsuhin. The second is the ō-suriagemumeikatana attributed to him as mainstream Fukuoka Ichimonji. These run wider in body, one taking an ikubi-leaning chū-kissaki, over a standing itame that flows in places, with ji-nie and the samemidare-utsuri; the temper is a chōji-midare mixed with gunome and pointed-ha, ashi and yō entering, ko-nie forming, and fine kinsuji frequent, the bōshi straight to a small round over a bō-hi. The published sources affirm these from every point as mid-KamakuraIchimonji work, dignified in shape and excellent in ji and ha, while granting that the attribution rests on era and school rather than a personal hallmark.
That candor is itself part of how the sources place him. On one of the mumeikatana the commentary states that "there is no decisive feature that compels the name Sukekane" (「助包でなければならぬという極め手はなく」5) and no point prominent enough to single out as his alone, yet that "there is no dispute it is a fine sword" (「名刀であることは異論がない」6). What sets the signed tachi apart from the rest of Fukuoka Ichimonji is read through his own traits rather than by contrast: the high, chōji-dominant flamboyance, the bright midare-utsuri with its mizukage and jifu, and the devotional bonji, sankō-tsuka-ken and gomabashi carving that the suriage attributions, showing only a bō-hi, do not carry. Among the school's named hands the sources rank the showy chōji of Sukezane, Yoshifusa and Norimune; Sukekane keeps that flamboyant manner while Yoshimochi turns quiet, and so the published record affirms his mumei pieces from the period and the school.
Fujishiro grades him Jō-jo saku, a high rank among the Ichimonji smiths, and the weight of designation behind his name is concentrated rather than vast: two of his blades hold the prewar Jūyō Bijutsuhin, the Important Art Object designation, and two more are Tokubetsu Jūyō, while the separate small-mei Sukekane the sources cite stands at 国宝. The provenance recorded against his tachi runs through houses of consequence, the Mōri by way of Mōri Motomichi, the Tokugawa line through Tokugawa Iesato, and the Asano family. His finest signed work is held now in the Tokyo National Museum and at Shinonome Jinja, kept as patrimony rather than anything that trades. Genuine signed Sukekane tachi survive in only a handful, and an ubu, signed example in its original form is among the rarer things a KamakuraBizen collector could hope to encounter. Of his recorded whereabouts almost nothing can ever come to market, and the one tier that might, very occasionally, is the Jūyō or Tokubetsu Jūyōmumei attribution, a landmark when it appears.
