What size are you looking for? For hunting I'm thinking right around 4" (give or take) is a perfect size for cutting and skinning...
If you're looking for something up in that higher range, Bark River makes some nice knives in a variety of steels with a large variety of handle materials... A2 or 3v for toughness, (requires a bit more regular maintenance to avoid rust spotting), or s35v or elmax for stainless, (holds an edge longer, but a bit tougher to sharpen when sharpening is needed)
Benchmade saddle mountain Skinner or Hunter are nice options in the >$100 range... s30v steel, again, good edge holding and stainless, but tougher to resharpening when needed.
Knives of Alaska is another solid option in the >$100 range; d2 steel. Not a true stainless, but almost, great option for toughness and edge holding with near stainless properties, another one that can be tricky to sharpen though when needed.
All those are made in the USA too if that matters to you or him.
If I were I were to pick a knife myself in that range though, something a bit more exotic, in your high end, (if he were to appreciate such things), I'd go with something from Arno Bernard, a south African knifemaker...
Here's one example, the Kudu, just under 4" with crodile leather handle; $320

Almost all his Knives are made in n690 steel (a couple are in s35v) which n690 has great stainless properties, respectively tough and holds an edge respectabl as well, all while not near as tricky to sharpen as the other stainlesses that I mentioned since it doesn't have even close to as much as the harder carbides.
