Do you know what kind of knife he carries now? Some people prefer large blades- to pound through rib cages and cut through bones. Some prefer small blades- to deftly cut around bones. Some like large sweeping bellies- so as to not poke through the hide. I prefer a caping knife. I find knives with sweeping (skinner profile) blades and bull noses ungainly to use, especially-and ironically- when skinning game. About the size of a paring knife, and about the same blade profile. Slim and pointy, it can get into the tight spots and make the cuts necessary to free joints. I've never had a problem with it poking through a hide. Pretty much every taxidermist uses a caping knife for skinning, and they skin more animals in a day than any hunter does in a season. But, if your uncle prefers a large blade, he may not appreciate a caping knife for what it is.
