I take the whole flipping thing like mud riding a truck. I wouldn't warranty it because the sky is the limit as to how much abuse could take place. A truck oughta be able to handle some mud cause it's a truck just like a CRK oughta be able to handle some wrist flicking kind of stuff. Gotta draw a line though. If you bog a truck down in the mud constantly it's going to develop major problems quick and it's the user's, not the manufacturer's failing, if you splash through a few mud puddles hunting or hauling something the truck should be fine. If you wrist flick your CRK all day long constantly like some sort of fidget toy it's going to wear out prematurely and it's your own doing, if you wrist flick your CRK only when you actually need to cut something it oughta be fine. But if I was in CRK's shoes I'd have a similar warranty because I don't feel the customer could offer definitive proof of how much they "flicked" their knife and I would just recommend they use a controlled sweeping motion because that would get rid of the argument one way or another.
