Sukemori is a name borne by multiple smiths working across the , Ko-, and Fukuoka lineages of Province, spanning from the early period through the mid- period and, according to certain records, extending into the era. The consistently observes that "the name Sukemori is found among both the group and the group," and that "there were multiple smiths working under the name" across these traditions. Extant signed works are few, and no dated examples survive, making research into the individual identities of these Sukemori smiths exceptionally difficult. Within the group itself, subtle differences in both workmanship and signature style indicate smiths of slightly different periods, with the earliest examples displaying an archaic manner closer to and later works connecting in quality to the line of Yoshifusa.
The Sukemori works are distinguished by a dense thickly covered with and fine , with standing out in the . The in these pieces is fundamentally -based with gentle undulation, mixing small and ; adheres strongly, and runs frequently. The characterizes this manner as decidedly more archaic than Fukuoka , noting that "the exhibits strong , displaying an archaic manner." In contrast, the Fukuoka Sukemori works of the mid- period present broader proportions, clearly displayed in the , and magnificent incorporating , , and angular elements in .

Signatures range from boldly cut large characters executed with thick chisel strokes to finer, more angular inscriptions, and the notes that "no other example is known of a signature style of this kind" for at least one distinctive variant.
Across both the and traditions, the repeatedly praises Sukemori's works as — sound and well-preserved in both and — and consistently employs evaluative language citing "extremely brilliant and gorgeous" tempering, "flamboyant and brilliant workmanship," and a "bright and clear" overall impression. The finest Fukuoka pieces are singled out as "one of the foremost excellent examples among this smith's extant works," while the examples are valued for their high documentary significance as material that "helps to remedy gaps in the tradition." The Ko- works, occupying a transitional position between the two main groupings, are recognized for their somewhat archaic character in both form and forging style. Taken together, the Sukemori oeuvre illuminates the continuous evolution of the school from its earliest classical phase through the splendid florescence of the Fukuoka tradition, and the survival of multiple signed examples — including rare blades — provides irreplaceable evidence for the study of this major lineage.
