Other Tools not often considered..

[Timelord]

1) Solid fixed handled quality entrenching tool. Good for camp & combat (no, not camp combat!)

2) Large butchers cleaver with may be a foot & half handle.
The blade will have a quality hardened edge with a softer back/main body for durability.Other edges/shapes could be ground into the top & back for utility use. A tang that extends through the wood handle can protrude out the back for prybar use - as configured in some famous military knife designs. It would basically be as an axe or more like a tree cutting or hedging bill but a deeper blade. The front edge could be given a dull chisel point to used as an expedient spade. These cleavers are dirt cheap on car bootys or 2nd hand tool markets etc. The end result should be pretty indestructable and have a variety of roles. Should be able to fell a tree or dig a trench or pry a lock or hack through just about anything.
