I guess my Buck 192 & AG 192 Vanguards are my favorite sleepers - even often forgotten by the Buck folks. They just fit right in the hand - are well balanced - and sharp, with their 4.1" fixed drop point blade, wood handle, brass pommel and finger guard, and leather sheaths. I suppose the 'all weather' 692, with it's rubberized handle and nylon sheath, might be better for some. I have the 420HC bladed 192, same material as the 692, and the super S30V AG 192, which is almost too pretty to use. The standard 192 would be great for the majority of hunting, camping, and survival uses - with the understanding that a camp axe/hatchet would be carried for 'real' chopping.
For SD in an urban jungle, I carry a revolver.
