Hello I know nothing about knives but my aunt found this one on the shores of Lake Winnipeg and asked if I could find out it's Origins. Can anyone help me out from the pictures taken? I believe it says Ka Bar Olean NY from doing some internet research. Everything I read says it is a combat knife used in war I'm just wondering how it ended up in Lake Winnipeg LOL. And what the actual age would be. It definitely looks like an antique. Any help is greatly appreciated thank you! I cannot figure out how to add a picture to this thread so if you reply I can send the photos for you to review.
