[ Highlight ] The Uta school was founded by Ko-Nyudo Kunimitsu at the end of the Kamakura period and flourished until the end of the Muromachi period, with Kunifusa, Kunimune, Kunitsugu and others active in the Nanbokucho period. Among these, works that do not descend from the Nanbokucho period are known collectively as Ko-Uta. The influence of Norishige, Ko and other predecessor swordsmiths in the Etchu region, such as Koshu, can be seen in the style of this work, which also incorporates Soshu-den. This work has forged surface with itame grain mixed with wood grain and changing grained patterns appeared surface, with a thickly nie attached jigane and a chikei appeared, and in addition, the colour is slightly blackened and the grained surface is characterized as if it were from the northern part of Japan.
