One thing that I have done over the years is to accumulate a number of knives. I currently have Kershaw, Buck, Shrade, Leatherman and a pile of "Potluck" brands. I'm sure that most of you are in the same boat. But, there is one thing I haven't prepared for. And, that is, to keep them sharp. I have started looking at various products in stores to do this. But, there are a lot of products for this purpose. I have seen Arkansas stones, diamond "stones", rods and other gimmicks to do this work. There are electrical sharpeners but I want something that I can use anywhere. I have used a whetstone a little, but I am not sure if that will suffice for stainless steel. Your assignment, fellow members, is: "what do you use? What is your opinion of the best products for this?
