My favorite skinning/dressing knives are the Buck Vanguard (rubber handle) and Buck Outdoorsman. I bought the Vanguard for $18 when Academy Sporting Goods was clearancing them several years ago and that was a great investment.

My favorite utility knive to carry on me when hunting is the Wenger Ranger Hunter Swiss Army Knife. My MIL found one of these in Germany on a trip back there (home for her) and brought it back.
