well, I'm no expert, but I have a bunch of knives of varying sizes and shapes which will all pretty well work for dressing out game (deer, turkeys, anything), but I can say that I probably consider this kit my "main" skinner, as I strap it on most of the time when hunting - I use the saw to cut limbs to clear shooting lanes.

See the Outdoor Edge Packs? I have the "Griz Pack" (which is identical to the "Trophy Pack" except for being a plastic sheath instead of leather; cheaper), but I wish I had gotten the "Kodi-Pak" because it also has the small caping/skinning knife which is good for getting in tight places esp. on turkeys ducks and other smallish animals (fish too). The Outdoor Edges are quite inexpensive, and thus a pretty darn good value IMO. A real budget choice. The saw blades are replaceable, btw. I'll highly recommend having some kind of little saw for shooting lanes and taking little limbs off trees if using a climbing stand - you want that tree trunk as smooth as your last girlfriend's... ermm, ya know, hands.
Some day I WANT to get one of these (below), when I have the money (they are a bit pricey, but not terribly bad). I LOVE the "Muskrat" knife portion of these kit - that muskrat could really get up under skin easily, and Knives of Alaska is quality stuff:

Those are some really nice combos. The muskrat is the rounded knife, with an edge almost all the way around.
Oooh, man, look at the Knives of Alaska "Hunter Pro Pack". I really like that since it's got (1) a hatchet, (2) a general-purpose camp knife, (3) a muskrat (skinner), and (4) a "cub bear" (small caping/skinning), all for $220. Nice! Or better yet, the super pro pack - it has all of the above plus a saw for just $10 more ($230). Man I know what I want for Christmas now - anyone know who has the best prices of K.O.A. stuff? Actually, if you or I or anyone get a kit like that that super pro pack in the nylon pouches thingy, ideally it would ALSO come with a sheath for JUST (1) the small caping knife (for gutting an animal where it lay), and (2) the saw, so you can have these 2 items with you at all times. The other items you won't need till back at camp (skinning, hatchet for bones/joints, and general camp knife), so they can stay in the nylon pouch thing. I don't really see a need for the large butcher knife looking thing, since a hatchet will perform that function, AND cut small wood as well. Also don't see a need for a gut hook. Yeah, it might save you 1 or 2 seconds time and perhaps help keep you from cutting down into the guts, but with a little skill and care, a plain knife edge works fine.
There's a zillion other choices too out there, too, of course!
Other points:
-Always have at least 2 or 3 EXTRA knives back in camp or in the pickup in case your primary goes dull, particularly if you think everyone in camp is going to bag game.
-If you knives are very sharp, or even if they are not, be VERY careful when gutting or butchering game - you can easily lose part of a finger if you're not careful, and man it smarts for weeks healing up. I've never had a REALLY bad cut, but one friend of mine did while gutting a hog, and he had bandanges on his hand for weeks.
-As far as fixed vs. folding, I like to have several of each and always have a good folder in the pocket. But for serious skinning/butchering, a fixed is probably preferred because (A) it's easier to clean afterward than inside the folder's liners, and (B) it's NOT going to fail and you and cut a finger off or nearly off like a folder COULD if the locking mechanism fails. A fixed blade worn ON YOUR PERSON however has the drawback of being largish and thus can catch on brush or feel uncomfortable if you take a nap on the ground lying on your side (well, I've heard people do this in the woods
). I wear one anyhow most of the time hunting.
P.S. I consider my "SigTac" neck knife to be my primary caping knife for birds & fish:

Hey, if you want a little caper with a gut hook, here's a neat little budget one:
