The Cold Steel Two Handed Machete:
My brother-in-law gifted me one of these for Christmas, and if you're looking for a cutting/slashing/hacking implement that's lighter than a full axe, this is the one to consider. It weighs under two pounds, is easy to carry on a vehicle, and is just the ticket for lopping limbs on a shooting lane, trimming trees, or light cutting chores where a full axe might be too much.
Mine lives under the bonnet of my Mule and it'll stay there for the forseeable future. The Cold Steel Two Handed Machete has the PawPaw seal of approval.
