Rusty, the reason you're getting "faint bad vibes" is because it looks like a Nazi "Youth Dagger" or other presentation knife. It's not related to those, it's a copy of a much older style Hitler was also fond of, but those of us who've been to US gun shows invariably see and get disgusted by the Nazi pieces.
At gun shows, you'll see a table sometimes with just ONE piece of Nazi memorabilia, usually one of those damn daggers. In such cases you're often seeing a subtle "message" to other like-minded and I avoid such tables like the plague.
In other cases you'll see a mixture of all types of WW2 memorabilia, Japanese, Allied, Nazi. That guy is less likely to be a white supremecist and more likely is a genuine serious collector...ironically, he could have a lot MORE Nazi stuff on his table and yet have his head on straighter than the guy with just one piece.
Weird, ain't it?
