I use a buck folder as my field knife for dressing, but when there is work to do I use what the butcher uses. Try Russel-Dexter professional knives. It's what the restaurant and grocery store fellas use. You can find them on E-bay for about 10-15 bucks a piece. Sure they have plastic handles, who cares. The blades are high carbon steel and sharp. They have a ton of models available with just about any blade you want for boning or skinning.
I figure if guys can make a living with them, I can cut up a few deer with them.
