For example, I contacted Chicago Knife Works, as they are one of the sellers on Amazon.com. I was looking at this knife. I received a response from CKW saying "We buy directly from ESEE knife authorized distributor . Any item purchased from us will be covered with manufacturer warranty as you buy from any other authorized dealer of ESEE knives . Thanks, Chicago Knife Works " I searched for this dealer but couldn't find them on this site. How do I verify they and others are legit if they're not on this site's dealer list? .. and yes, I read the warning for buying on Amazon / eBay.
