Hello to all. Long time collector of nihonto but new to teppo. I found this at an antique shop while on vacation in Tennessee. Thanks to some Facebook friends, I know the signature is Goshu Kunitomo Tayosuke Katsumasa. It also contains Niju makibari. Would really enjoy learning more about Tayosuke Katsumasa such as time period he worked, how he is viewed as a smith compared to other Smith's of the time. Any information is greatly appreciated! https://i.imgur.com/caJc0US.jpg
