Hypothetical question here. Let's say Jack bought a FFG Endura and the lock broke. Then he sent it in to Spyderco for warranty work, along with a receipt. Spyderco examines the knife, and although all markings are correct, as is the price, they determine the knife is a fake. Now, what's the protocol for this? Assuming Jack didn't know the Endura was a fake, what's the call?
