Having been a "Professional" game processor in a past life, I can make a few recommendations: Don't use a folder, there is an inherent "potential" weak spot with a pivot. I recommend a good fixed blade. Also, don't be afraid to buy a knife with BG42, CPM420, or some other high end stainless alloy. Carbon steel has nothing over these steels.
If you are limited to a folder over a fixed blade for some reason, the CRK Sebenza is the one. As has been said, it can be field stripped and cleaned very well. The Wegner cannot and I will not carry a knife that cannot be cleaned in the field. You can't imaging how much blood, meat, fat, and hair invade the very recesses of a folding knife in field dressing! When you can't disassemble your Wegner, or most other factory knives, you can't get that junk out of the cracks and crevices. A dirty knife has the posibility to contaminating the meat in any subsequent game processing you do, and also the potential to give you a good case of food poisoning!
Bottom line, get a good custom or production-custom semi-skinner or drop point. If not, get a Sebenza. Thanks for listening.
