Special feature : Nobukuni school has spreaded to all over Japan during Nanbokucho period Enbun Era (around A.D.1356~) to modern ages but all of them started from Yamashiro province.
I think the blade was forged around at end Nanbokucho period because of the quality of engravement. Though NBTHK has judged the blade was forged at early Muromachi period around Ouei era (1394~1427).
We recommend this blade for keeping nice condition and for one of the good historical document about Nobukuni school.
