Yukihide is a Ko-Bizen smith active from the close of the Heian period into the early Kamakura period, traditionally regarded as belonging to the Tomonari lineage. In sword reference works (meikan), the name Yukihide appears among both the Ko-Bizen smiths and the Ichimonji group; however, blades bearing his work are consistently appraised as Ko-Bizen. The NBTHK has observed that "there are also large and small styles of signature among works bearing this name, suggesting that there may have been several smiths using the same name." Extant signed examples are exceedingly few -- fewer than ten are known to survive -- making each signed piece important reference material for understanding both his working range and inscription forms. His blades have been transmitted in distinguished collections including the Daitokugawa family, the Sendai Date family, and the Tokugawa shogunal house.

Yukihide's forging is characteristically itame-hada mixed with mokume, with abundant ji-nie and fine chikei, producing surfaces on which midare-utsuri or jifu-utsuri stands out, sometimes reaching to the shinogi. Several setsumei remark on an exceptionally well-packed ko-itame-hada of such refinement that it "could be mistaken for a Kyo (Kyoto) product." The hamon is fundamentally suguha-toned or based on shallow notare, mixed with ko-gunome, ko-midare, and ko-choji -- the NBTHK noting that among Ko-Bizen works generally, "flamboyantly irregular patterns are few." What distinguishes Yukihide within this school is the recurring presence of saka-gokoro -- a reverse-slanting tendency within the tempered area -- together with the formation of nijuba through dotted tobiyaki and yubashiri running slightly apart from the hamon. These two traits are cited across nearly every designation as his signature characteristics: "from olden times, Yukihide has been admired for points such as the inclusion within the ha of a reverse-leaning character and the appearance of nijuba." The presence of saka-ashi, ko-ashi, kinsuji, and sunagashi further enlivens his work, while the nioiguchi is consistently described as deep, bright, and clear.

Yukihide's blades are praised for possessing an archaic fragrance (koko) and a deep, elegant atmosphere characteristic of the finest Ko-Bizen production. The NBTHK repeatedly affirms that his pieces are "well unified with a high level of dignity," and describes outstanding examples as works of kanzon no yuhin -- excellent, fully surviving blades. The condition of ji and ha being kenzen (sound and well-preserved) is a point "especially praised" across multiple designations, underscoring both the quality of the original steel and the remarkable survival of these works across nearly a millennium. Taken together, his oeuvre clearly demonstrates the general style typical of the late Ko-Bizen tradition while bearing unmistakable individual character, securing his position as one of the most distinctive and collectible smiths of the school.
