This katana is attributed to Chiyozuru Morihiro of the Chiyozuru school, which flourished in Echizen province from the late Nanbokucho period through the Muromachi period. The blade features a bright, straight temper line (suguha) with some itame hada. Despite being significantly shortened (osuriage), the blade retains a substantial width and is in very sound condition.

The Chiyozuru lineage took root in Echizen Province during the Nanbokuchō period, and the setsumei consistently trace its origin to Rai Kuniyasu (来国安). He is said to have been born in Yamashiro Province, with one tradition holding him a grandson of Rai Kunisue; he later moved to Echizen, where the meikan place him around the Jōji and Sadaji eras (ca.
1362 to 1368). A parallel tradition, recorded on the signed tachi attributed to Morihiro, names Chiyozuru Kuniyasu[[c:1]] as a disciple of Rai Kuniyasu and the founder of the line. Learn more →
