I'm hoping someone knows what this is. What I know is that an occupation soldier brought it home from Japan and that it has been with that family ever since.
Condition is really nice. The blade has no stains (you see reflections of plants and things in my lousy pics) and has never been sharpened. It has a distinct Hamon, though I don't know if it is authentic or merely cosmetic.
I forgot to measure overall length, but can do that when I get home.
Is it even Japanese? Thanks, in advance!!
