Damn, you guys are pessimistic. There is no radically different shape to the edge(s) or handle. If you split this knife in half lengthwise, you'd have two slender straight backed blades, and I don't think a straight backed knife with modest belly would be "useless". I don't see the blade length itself as a problem. Usually when I notice a blade seems unweildy for smaller tasks, it's just as much because of the heft/weight out there; but this is a thin butcher blade. Folks complain about daggers having short/narrow grinds, meaning the blade thickens more quickly from the edge. Can anyone say Mora? I mean, really. Given a decent sharpening & reprofiling job, the edges on these will probably be thinner than most knives discussed on Bladeforums, meaning they will actually cut stuff every bit as well or better. Sure you can baton these. It will just chew up the baton; not prevent you from doing it entirely. The main disadvantage I see with this sort of double edge is that you can't put your thumb on the spine to apply more pressure when carving wood or something. But by the same token, the edge on these comes all the way to the handle, meaning you'll still have more leverage than a single edged knife with a useless choil.
Man used double edged blades to survive for thousands of years, and even to within just a couple hundred years ago on this continent. Spearpoint flint blades are FAR more common than drop points or any other shape.
