A bud of mine uses his Case Canoe when he has nothing else to field dress deer. This is his Case, given to him around 1964, he had field dressed a deer the week before, and had not cleaned it!
If anything, this proves you don't need a big, honking knife to field dress a deer. Caveman probably did it with a flint shard.
I gave him two knives and asked him his opinion on them. A gave him a Grohman Canadian belt knife, (on top) and the bottom knife, a #4 Survival with a 5.5 inch blade.
He preferred the Canadian belt knife. It was smaller and did not get into the way.
When I have skinned deer, this pattern is great. Wide, thin, great curvature, and keeps my hand away from the hide.
Recently purchased one of these at Cabelas.
This is a Buck Vanguard with rosewood handle and S30V steel. Blade is 4.25 inches. It feels good in the hand, I like drop points as I am less likely to stick myself. The regular Buck Vanguard is 420HC, and is a very good design for a store purchased knife. I do prefer fixed blade knives as I hate having to clean out the blood, hair, guts, that get inside a folding knife. There is no doubt a folding knife is more compact, and that is an advantage.
I did field dress a deer with a Camillus Yellow Jacket dual locking trapper, Model 716. It worked, but I would rather have had longer blades and a fixed blade knife to split the pelvis.
