Any advice appreciated. New to looking at nihonto, and I'm looking for my first collectors piece. I can't read the NBTHK certificate, but everything seems in order (it's a mumei and Yasuhiro attributed). Basically, I am wondering if this is a good price, if everything looks legit, and what in the world the description on the certificate might be. Thanks!
