Artisan Rai Kunimitsu (来国光)
Era Late Kamakura period to early Nanbokuchō period
Explanation Rai Kunimitsu is traditionally said to have been a son of Rai Kunitoshi. He was active from the closing years of the Kamakura period into the early Nanbokuchō period. Among extant works, the earliest dated example bears the year Karyaku 1 (1326), and the latest is dated Kanno 2 (1351). His workmanship is notably diverse: alongside the traditional, true suguha, there are works in a suguha-based style mixed with ko-gunome and ko-chōji, works in a suguha-based style with a slight ko-midare tendency, works in a notare-based style mixed with gunome, and also irregular tempering in a gunome-based manner.
Although this blade is o-suriage, it retains slightly deep curvature with a koshizori-like appearance. The jigane is a closely forged ko-itame with thickly applied, extremely fine ji-nie and delicate chikei, presenting bright steel. The hamon is fundamentally chu-suguha with ko-gunome interspersed; ashi enter well, the nioiguchi is somewhat deep, and thick ko-nie adheres. In addition, activities such as fine kinsuji, hotsure, and uchi-noke are abundant, and the boshi turns back in ko-maru. These features strongly manifest the characteristic traits of Rai Kunimitsu in both ji and ha. With its bright, vigorous edge and plentiful hataraki—hotsure, uchi-noke, and kinsuji among them—this is an excellent blade with many points of appreciation.
