What are the characteristics of a good Elk knife? How long? Shape of blade? Folding versus fixed blade? I bought a Schrade "Jim Zumbo" signature knife on sale over the weekend which has about a 6" fixed blade, a gut hook, and maybe 2"-3" of saw teeth on the back of the blade (Schrade also produces another Jim Zumbo knife which has a shorter, maybe 3.5" blade, which is a folding knife -- this isn't the knife I'm talking about). Has anyone used this 6" fixed blade knife and how did it suit you? I have other shorter knives which I would probably have available when dealing with an elk, but read somewhere that it is useful to have something a little bigger -- at least for some of the meat handling activities -- when dealing with an elk.
