Hi, I'm looking for some assistance with purchasing a sword for my father. He's been a martial artist for decades, a black belt in Karate and Aikido. He's always wanted, but never purchased a true Japanese sword, so I decided I'm going to get him one.
I've done some research and found what seems to be a reputable store with a selection of antique swords with NBTHK paperwork.
The problem is I don't know what I'm looking at, and was hoping for some help in understanding the condition of the blade.
I've inculuded some photos from the listing. It is attributed to Uda from the Muramachi period. Comes with fittings, mounted blade down, and a fairly fancy sheath for ~$4K USD.
