For gutting I use my Buck 119. They are a strong and durable knife, plenty sharp and they last a long time. My Dad still has his which he got for Boy Scouts in the early 60's. It is a little long maybe, but you just have to be careful around the organs. I've never really had a problem with the length. But the reason I like it is that I can cut right up through the rib cage of a deer with practically no effort. I just find this easier than shoving two hands up inside with a little knife and then cutting and pulling everything out. The 119 just unzips the whole deer and you can even cut through the pelvis, although I usually don't do that anymore.
I also have a gerber folder that I used to use but something about the blade geometry just doesn't cut like the 119. I keep my knives sharp, and the gerber "feels" very sharp but it loses the edge fast and for some reason it never just slices like the 119 does even when sharp. I still use this knife often for carrying but its actual performance is inferior in every way to the buck. I had a buck 110 folder for a while that I liked but a friend broke the tip off in a tree.
I use the 119 for a lot of the skinning as well. It has a long edge so it works for long pull strokes. My friend uses disposable scalpels for his skinning and he gets it done and probably does it neater than I do but I still think the buck is faster, and it doesn't require frequent sharpening or replacement of the blade (like some of the scalpels).
The last thing I use the buck for is quartering. Again, its size, sharpness are a plus for getting into the hip joints.
After the deer is quartered I switch to fillet knives to bone out and cut steaks etc. I have 3 fillet knives (one is a buck, and suprise suprise, it is the sharpest and retains its edge longest as well). They do dull up quicker especially when working around the bones so I sharpen them all up and then rotate them out as they get dull.
Anyway that is my long winded recommendation. I know there are other alternatives to the buck, but for its price (~$40 @ walmart w/ nylon sheath, ~$50 anywhere else with leather sheath) the Buck 119 is a great knife that will last literally forever and provide very good performance.
