Camp hatchet/axe

We used to collect pine-cones and lighter-knot. I agree with the folding saw comments. I also like a heavy machete, but I know how to use them, they take some time to become skilled with... they can be dangerous for someone not used to them.
But, still, my last few trips before becoming too ill... just cut it up at home and took it, pre-cut, with me. But you have to have the right vehicle, tarp and room.
I like cooking in the fire, fold the food, wine and spices into several layers of foil, bury into the coals and wait. BTW, use a shovel and long tongs. We called them hobo-packs in the scouts and on the ranch. Does well with potatoes too.
