Sukemori is a swordsmith of the late into the early period, known today only by a small body of signed tachi, each bearing a bold, large two-character mei cut with a thick chisel. His name is one of the standing Bizen attribution problems. The reference works enter a smith called Sukemori among the Fukuoka Ichimonji group, but the published sources hold that a clearly distinct, older Sukemori works in a Ko-Bizen manner, and that it is to this archaic hand that his recognized signed blades belong. The point is made plainly on his Jūyō Bijutsuhin tachi: although the meikan list an Ichimonji Sukemori, "there exists a Ko-Bizen Sukemori clearly different from that one, and this blade is likely his"1. His signature style, the same source adds, is more old-fashioned than that of the Ichimonji Sukemori, so even the name on the tang reads as the older hand.
The temper is the tell of his work. Over a jigane of itame he sets a broad suguha-tone that undulates gently and becomes "wet" in feeling, mixing ko-chōji and ko-midare into the line, with ashi entering abundantly. What separates him from his Ichimonji namesakes is the strength of the nie: it adheres heavily through both ji and ha, sunagashi runs frequently along the temper, and the nioiguchi tends to shizumi, a subdued depth rather than a bright clove-flower. The published sources, weighing the several Sukemori smiths they have examined, judge this one "the strongest in nie and the most archaic in tone"2. The flaring chōji and high clove heads of the mature Fukuoka school are absent; in their place is the quieter, nie-laden Bizen of an older generation.
The jigane carries that same archaic character. The itame is dense, thickly covered with ji-nie and entered by fine chikei, standing a little in places and admixed on one blade with a touch of nagare-hada along the ura. The shape agrees with the dating: slender in build, the sori set at the waist and retained even after shortening, running to a chū-kissaki, the dignified bearing of the early Kamakuratachi. The bōshi runs in a midare-komi and turns back with a ko-maru tendency. Taken together, the published sources read the whole "as more archaic than Fukuoka Ichimonji, a Ko-Bizen work of around the early Kamakura"3.
Within his small surviving group the degree of flamboyance varies, and the variation is itself instructive. His more decorative tachi, an ubu blade keeping its three-character mei though the inscription is corroded, widens the body and raises the line into a chōji-midare mixed with gunome and small notare, the nioi deep with ko-nie and kinsuji running through. Yet even there the judges place him by style and signature in the Ko-Bizen group rather than the Ichimonji. The name recurs, the published sources note, in both the Ko-Bizen and the Ichimonji lineages with differing workmanship and differing manners of signing, so several smiths used it across both schools, from the very end of Ko-Bizen into the Nanbokuchō period; this Sukemori is held the most archaic of them.
What sets his hand apart from both its neighbours is exactly what the judges name. He is held apart from the flamboyant chōji-midare of the mid-KamakuraIchimonji by the calm of his suguha-toned line and the depth of its nie, his "signature style older than the Ichimonji Sukemori"4; and he is distinguished from the plainer old-Bizen hands by the strength of that nie and the sunagashi that enlivens it. He stands before the school's great flowering at Fukuoka, one of the quiet archaic roots from which the brightest of the Bizen traditions would grow.
For the collector he is a rare early name carried by a slight but high record. He has no National Treasures; his designations run instead through an Important Cultural Property tachi held at Kitano Tenmangū Shrine in Kyoto, a prewar Jūyō Bijutsuhin tachi published in the Kōzan Oshigata, the Kantō Zuiroku and the Nihontō Taikan, a Tokubetsu Jūyōtachi, and two Jūyōtachi, the Jūyō Bijutsuhin piece having descended through Shigetaka Kinkyō of Toyama. The published commentary calls his finest signed tachi "sound in both ji and ha, a well-made example"5, and holds the ubu signed blade valuable as reference material for the school. These are designated cultural property and long-held heritage, not blades that pass through the market; the few in the Tokubetsu Jūyō and Jūyō tiers come to light only seldom. A signed Ko-Bizen Sukemori in private hands is among the rarer things a collector of early Bizen could hope to encounter, and a document, when one appears, of how the Bizen line stood before Ichimonji.
