So I picked up one at a garage sale 30 years ago and still have it. Looks old, even when I bought it 30 years ago . It's pretty much been hanging on the wall of my reloading room because I think it's cool. It's in a sheath. How do I know if it's the real deal or a fake sold to tourists? Fake or not, it still looks cool on my wall and it'll stay there. A buddy of mine saw it recently and asked if it was real or fake. I've been researching on the web and it's about as clear as mud. Any insight here?
