This is the "Swiss Army Knife" of camping tools. In one unit it has an axe, shovel, pick, wood saw, hacksaw, pry bar and hammer. Pretty much every medium tool needed for camping.
The unit would be built using basic machine tools.
The use for this would be for camping, survival and as a general, carry-in-your-trunk useful tool
The shovel head pivots to get out of the way of the ax and hammer and to be be brought into position for use.
The handle is hollow for storage of wood and metal saw blades.
