If your knife won't hold an edge to gut/skin one deer, I'd be looking to upgrade my knife more than looking for a knife sharpening system. I'll touch up a knife after a use, but rarely during.
As far as sharpening, I'm a big fan of hard Arkansas stones, free hand sharpening.
Yeah, that sounds like what I'm talking about. A hard Arkansas stone is not really where you want to start with a really dull knife. Once you have a decent edge established, touching it up with an Arkansas stone will keep you razor sharp.As far as the Arkansas stone, you talking the ones that are about 5 or 6 inches long by 2 or 3 inches wide that come in the wooden box, right? Many moons ago I bought one, but I think it's a soft stone, maybe that's the reason it takes FOR-EV-ERR to sharpen anything?
