For many years I used a stone to sharpen my knives but due to a recent vision problem I can no longer hand sharpen my knives. I just purchased a Work Sharp system that people brag up and will give it a try. I carry a basic folding utility knife with the replaceable blades and a fixed 6" blade knife. I will butcher 3-4 moose, maybe a Grizzly, wolf and a caribou each season and only replace a couple blades in the folding knife which I do all the skinning and save the fixed blade for the meat separation. I don't even take a sharpener to camp let alone in the field. This has been working well for many years.
