I recently recieved one of Mr. Barr's One-eyed Jacks in a trade. I like everything about the knife, plan to EDC it. However, the liner-lock has become loose, and there's a small amount of lateral blade play. I e-mail Mr. Barr, ask him if he might have time to refurbish the knife, and how much it would cost. He e-mails me back, the same day, says he's sorry to hear about the problems I'm having, drop the knife in the mail with a $10 dollar bill to cover shipping, and he'll get right on it. I ship it off the next day, with a note that tells him, again, that I'd be happy to pay for his time/materials. I don't consider this a warranty issue, because I have no way to know how the knife was used prior to my coming into possession of it. He recieves it, fixes the liner lock, tightens up the pivot, polishes scratches out of the blade and sharpens it (I didn't say anything about those two issues), and ships it back to me the next day. The next day. Total time, from when I first e-mailed him to when I recieved the knife back from him, is less than 2 weeks. 10 days, to be exact. Pretty incredible, in my experience. Thanks again, Mr. Barr.
