Doesn't get that cold over here, -17C was the coldest I saw on my thermo this winter and -5C is the coldest I've been out hanging, so I don't know how it is when the ground is rock hard. But I just cut my own stakes from deadfall. Snap a branch, sharpen the point, and if I'll be using it for more than a day I'll notch the other end to help keep the cord on. Then I just stamp it into the ground and disgard it when I leave. If I'm going to carry a fixed blade with me might as well have it pull it's weight
