I have cleaned a lot of salmon and big game and I always get asked to sharpen knives in camp. I have them all but all I use is a round diamond hone to set the edge and a steel to finish. This will quickly produce an edge that is perfect for cutting through fish skin and too sharp for a skinning blade. It is fast, easy and cheap and unless you are carving hardwood you don't have to stone the blades for hunting and fishing.
