Ultimate camp/survivor tool?

You just do what the army do, carry a regular entrenching tool and a pickaxe... "suck it up and put your back into it, you orrible little scroat"
Yes its extra weight but you can hit people with pickaxe handles as well... look at it like exercise, an army pickaxe only weighs about 10lbs or so, the army have managed for years to dig vast trench systems with them... why spend all that cash?? on some fancy schmancy kit thats not really needed??
If youve all got spare cash send it my way, I could do with a new car....
