Cliff,
The handle on the camp knife was too short. I had trouble comfortably squeezing my hand between the blade and the birdshead. I photographed the knife in my review after I had already ground off the obnoxious plastic extension on the guard that extended lower than the blade. I suppose I could grind off the end of the grip too, but I don't particularly care for the knife so I don't think I'll invest the time. The blade stock is thin so the grind is not too bad. The worst thing about the grind is that it does not extend all the way to the back of the blade.
The gaucho knife does have a round, pakkawood style handle. The conical design with a wide back end and the blade overhang at the front end tends to lock the hand into the grip and minimizes the slipping problem. As you note, the tang is not thick where it enters the handle. It works great for cutting food etc., but would probably bend or break immediately if heavy prying were attempted. This is evident when holding the knife, so I doubt users would be tempted to perform such (for this knife) abuse, for the same reason few people pry with fillet knives. I don't find index finger contacts with the blade to be bothersome, but I wasn't doing stabbing type actions. Perhaps in some butchering applications this would be a problem, where a slippery handle and point insertions were both present. For the kitchen tasks I was doing my finger rarely if ever contacted the blade. The overhang does provide some confidence and protection against the stubbing type of accident, where the knife point inadvertently sticks in a cutting board or table edge or similar hard substance, and the hand rides up on the cutting surface of the blade.
The camping knife is my favorite. I think SMKW calls it a cleaver, but it definitely is not. The blade is thin and I would expect serious damage from chopping through a bone. It does great work cutting meats and vegetables in the kitchen. The unfinished wood handle with rings cut into it does provide for a more secure gripping surface than the gaucho knife has. The larger diameter handle fills my hand better also. The only advantage the gaucho knife has is its slightly smaller size makes it more comfortable to carry.
