Kuniyuki is regarded as the founder of the Taima group of Yamato Province and was active during the late Kamakura period. Among works of the Taima group, extant signed examples are few; only a small number survive with signatures by Kuniyuki and Aritoshi, while almost all others are works attributed as mumei appraisals. His two-character signature appears in two modes: one rendered in kaisho (formal block script) within the kunigamae enclosure, and another in gyosho (semi-cursive) form. Both varieties are considered extremely rare, and any zaimei tachi by this smith commands particular scholarly attention.
Kuniyuki's forging is a well-worked itame-hada mixed with masame, often showing areas of flowing grain and thick ji-nie with chikei appearing throughout. His hamon is typically suguha-based, gently notare and mixed with choji or small gunome, tending at times toward ko-midare. The habuchi characteristically shows hotsure, while within the tempered area sunagashi runs frequently, interspersed with kinsuji. The nioiguchi is bright and clear. His boshi tends toward sugu, turning hakikake or ending in yakizume — a disposition considered typical of Yamato workmanship. Activities such as chikei and kinsuji intermix freely, giving a lively effect to the steel.
Kuniyuki occupies a position of particular importance as the progenitor of the Taima lineage within the broader Yamato tradition. His work demonstrates the defining characteristics of Yamato-den forging — the prominent masame tendency, the bright and clear ji and ha described as akaruku saeru, and the restrained yet animated temper line — while displaying a refinement and individuality that distinguishes his hand from later Taima smiths. The rarity of signed examples only heightens the significance of each surviving blade, and his best works are noted for their kenzen condition and sound preservation.

At Taima-dera in Yamato Province, the temple from which the school takes its name, a body of swordsmiths gathered in the late Kamakura period under Kuniyuki, who is transmitted as the founder of the line. The Taima group is counted among the five schools of the Yamato-den, the others being Tegai, Senjuin, Shikkake, and Hosho, and like its siblings it grew out of a monastic milieu in which the smiths worked in dependence upon the temple.
