Previous answer is
Awataguchi Omi Kami Tadatsuna(2nd generation)(Ikkanshi)
Special feature: 2nd generation Tadatsuna is a son of the first generation Tadatsuna and succeeded 2nd generation.
He got the tytle Oimi Kami and called Ikkanshi. He made ashinaga cyoji midare and Doranba mainly and also very good
at Horimano on the ji which was learned from Fujita Tu-i. I watched the Horimono of Hujita Tu-i and well impressed
a lot from the fantastic
engraving. It is true that Ikkansi Tadatsuna engraving is high evaluation but I think the sword itself must be evaluated Jigane and Hamon.
from that point This Ashinaga Cyoji midare hamon is high ranking sword value I think.
