I understand that kershaw resharpens knives that you have purchased from them, if you send the knife in. My friend had a Leek coated in DLC, and while the coating has held up to the point where its almost unscathed entirely. He was curious if he could send it in to be re-coated, and if so, how much that would be. He shot them an email, but alas no reply. Thanks for the words all.
