First, think about what size game you enjoy hunting the most. Do you hunt mostly small game such as birds and rabbits, or do you prefer the larger game such as deer and bear? If you enjoy hunting just for the sport and only hunt for trophy prey then you want a hunting knife that is especially made for trophy hunting.
If on the other hand, you hunt to provide meat for your family or you just enjoy fresh meat then you want a hunting knife that will cut the meat from the skin effectively.
