'Bama doesn't have a monopoly on idiots at gun shows. I've only been to a couple gun shows up here in Wisconsin... but my gut impression is, they're a great place to buy used guns, a maybe-good-place to buy reloads (fire at your own risk), and a FANTASTIC place to buy genu-wine Chinese-made "Indian" artifacts.
Let's face it, your typical "gun show" is little more than a flea-market with higher prices. In my experience at gun-shows, flea-markets and carnivals, I have never come across a "handmade" knife that was worth a spit. 97% of them were horrible, edgeless imported sh!t with a pretty silk-screened handle (often, a wolf, buffalo, or other pseudo-Native American theme.

) The second 1% was "my dady forged this'un frum a old sewer pipe, I gwarantee it kicks azz, but no, I won't give you my name". The next one percent is just your general-run crap, in a pretty box marked "collecter's addition" (spelling mistakes included on purpose.) The other 1% were Ka-bars and the like at fair prices; nothing wrong with that.
Like other posters have said, it astounds me that some folks will happily drop $5,000 on a custom rifle, $10,000 on a bass boat, or $70,000 on an RV or recreational land, yet refuse to spend more than $20 on a quality hunting or fishing knife. What can ya say to that? Some folks refuse to be educated. Forget 'em.
