I think a simple fact that a few of you are ignoring is that these are production knives. You're not shelling out $600 for a custom flipper, that is given individual maker-attention. ZT is producing hundreds of these knives, if not more, and there are bound to be one or two that are overlooked by QC. But thats what your $260 buys, a production folder; and you know this going in. ZT has the upstanding reputation that they do, because through time and trial, they have worked with customers, and fixed the FEW errors that happen to occur. The fact that they are willing to work with you and make it right (because not all production companies will) speaks volumes to the integrity and standards upheld by their company. I personally have never received a knife that needed to be sent in to correct a defect (lol except for my umumzaan, but as it turns out, the lockbar was spot on to begin with), but if i did, i wouldnt flame the company unless they refused to make it right. Its easy to understand your frustration, no one wants to anxiously wait for the arrival of a new blade just find out its DOA, but when you buy a production folder, thats a chance you're knowingly taking, and ZT happens to produce some of the best production tools available IMO. Personally, i cant wait for my 0561 to arrive, and if it gets here with problems, sure I'll be irritated, but I have confidence ZT will take of of it, or replace the blade. I hope it comes back to you with all issues addressed; third times a charm bud!
