These two knives are always in my hunting pack. A Buck Folding Hunter and a Knives of Alaska Trekker Elk Hunter. The Buck stays sharp and is easy to sharpen. I will field dress/skin game or if I'm waiting for deer or whatever prepare a meal with if I get hungry. It is easy to clean and maintain.
My Trekker Elk Hunter is made D2 steel. It requires time to sharpen to get to shaving sharpness but is tough as nails. I've broke a Buck knife once working it too hard. I've hacked limbs with this thing on days I didn't think to bring a saw. It is more of a utility knife for me to keep the Buck sharp and ready for handling game.
