Previous answer is
Suke ? (Den Ko-Bizen)
Special feature: This blade made in around 1207 still remains.
Even today, with 800 years having passed since then,
Kissaki and Hamachi is rather wide. The first owner must be some kind of Daimyo(Japanese feudal lord). We were deeply impressed by this blade.
At a glance, the blade reminds of Awataguchi.
NBTHK judged this blade as Ko-Bizen.
