It may sound funny to some, but I went to Ace hardware and, on a whim, purchased an Accu-Sharp sharpener for $9.99. I'll tell you what, it was the best $10 bucks I ever spent. I had a new Ontario Airforce survival knife that I'd left in the box for a couple years because when I got it, the edge was very dull, and I knew that putting a good edge on it takes awhile. I tried the Accu-Sharp on it, and BAMM!!! It's like a razor after several strokes. I use it on all my hunting/skinning/filet knives now. Also bought an extra for my hunting bag. $10, you get a good sharpener, and save money. What more could we ask for?
