I found the store last week and my grandparents' basement cleaning up things after the passed away and I knew my grandpa participated in world war II but I don't ever think you went overseas but he had a bunch of Japanese equipment and stuff. Not quite sure if I should clean it off a little bit so I can read this the signatures in the descriptions better or just leave it how it is but it's very old and it looks like it was used by the chips in the blade.
