When hunting I always carry a belt knife.
For antelope to elk, I prefer a 3 7/8" to 4 1/8" semi drop point blade, bevel ground, .125" thick and slightly less than 1" width.
With this I can zip, open up, split, core bung hole, gut, skin, quarter, bone out and reduce cuts as the situation requires.
I carry a smaller fixed blade (3" or so) for back up in my back pack
.
I don't put any part of my hands/fingers as far up as the cutting edge when working on game. I usually have a knife with some restriction in design such as a applied or integral guard or at least a finger notch----but not always.
But I still have a pile of knives to field test, so I could move off of center as time passes.
There are more "small" things you can do well with a bigger knife than there are "big" things you can do well with a smaller knife. Not considering the extremes here.
Just my current opinions.
