I’m also huge fan of bark river as well other high quality makers. I have over 100 and I use them all.
The models you mentioned are all good, but each has a different role... and very different grips.
Thickness is true, but as the only maker in the US dedicated to full convex you must start with more steel. In recent years as their shop has improved ability to shape steel to convex they are offering many models in .125 or less thickness. Two of the models you mention have light models.
From what you mentioned, I wouldn’t pick any of those models. FR is one of the best field boning knife (short of a commercial victorinox curved boner) I’ve used, but a drop point in general are not great skinners. Gunny has earned reputation as a hunting, survival knife, military carry, bushcraft and does all well imo, but not the best in any, again imo. CS is Mike Stewart version of the grohman #1. With different edge profile, I view as General purpose bushcrafty - although I boned out big whitetail with it and I prefer it to Fox river for that task. The belly is nice but small and not a continuous curved and not a good skinning knife. All three of those have handles that are large and Or contoured - and for me I like slightly undersized handles, personal preference. All of these models plus the loveless replicas can all gut or quarter any animal however.
For the type of mountain processing I do, gutless bone out I prefer a skinning based design. Currently in stock at two online dealers is the classic loveless skinner. Others if you find used are mini kalahari semi skinner, trail buddy. Folks are afraid of skinners because you loose precision. But if the tasks are skin then remove muscles those patterns excel beyond a drop point imho. Interesting internet reading would be the Marbles woodcraft a very famous knife, also referred to as a sticking knife. Early 1900s you would stick one of your stock until it bleed out, then skin it, then remove muscles and butcher them for storage. All with a 4” skinner. Another good light one made by spyerdco the bill moran skinner. They will do everything but not gut very well.
For elk I carry the Classic loveless skinner in wood handle and weight 4 oz, and I carry their pro scaple II for my initial skin incisions, skin out lower legs and cape the head if I’m so lucky, and it’s a general camp chore knife. It weight 1.5 oz. if I were going after deer it would be the trail buddy.
Another reason I love bark river is their steels. Yep have a few duds like lambs mentioned but they took good care of me. If you’re fair at sharpening I’d stay with a2. Excellent overall performance and forgiving. If you can sharpen I like a few super steels but not all. My preferences are cpm 154, s35vn (altered version of sv30), 3v, cpm d2 (not d2) and a2. 3v and a2 will rust but if you can keep your knives vertical in pack that won’t. I coat mine anyway in veg oil.
So many excellent points already posted, mine is just another and in no way definitive to others. My experiences and a crazy knife nut who seeks out my way to process kills.
