>>1304420For big fixed blade well-known brands, I've had some issues with Condor. I'd only get those from a no-hassle return place and test them immediately. Not so much a scam in my opinion, rather unreliable production. Sorry, that's all that's springing to mind.
I mostly see scams on ebay... fake spydercos and whatnot.
Do you have a specific company(s) you're getting a bad vibe from?
