I use a Gatco sharpening system! I have had this system for over 20 plus years. Once you get the edge on a knife worked into where you want it, just a quick couple of swipes and you are back to a hair shaving blade. I have taken knifes that were "sharp" according to the owner and made them shaving sharp. There is a patch on my left arm where I test the edge. During hunting season, it is perpetually bare. In camp you will always see me around the fire sharpening someones knifes. That Gatco system has worked well for so long and appears to have another 20 years before needing new stones!
