Has anyone replaced the pivot washers in the Large Vantage Pro? I've been carrying my Large 347 for over a year and noticed considerable wear to the washers after disassembling the knife and cleaning it. I have also noticed that I can't fix the blade centering by tightening the pivot screw anymore. My feeling is that they need replaced. Does anyone know if you can get these from Buck without having to send the knife in? Thanks guys.
