I use several knives and select one specific to the hunt/task. When gutting and not cutting open the chest I prefer a 2 3/4 bladed fixed, easy to clean and less chance of cutting myself and extremely light to carry. If cutting open the chest I use a 5" fixed blade. Here in SD where we drive around and shoot deer one of my several 3" folders are used for gutting.
Elk hunting was always a walking and carrying a pack and a #7 Ingram with a 3 1/2 blade was used on the majority of my hunts.
Once home I use a Tim Olt bull nose for skinning, An F. Dick 5" flexible boner is used for the vast majority of my butcher work.
