Wow,
My opinion differs from pretty much the rest of the posters. Maybe I'm wrong, but I'm a believer in a good flexable folding knife and a sturdy fixed blade. A good leatherman or Gerber utility tool, and a good fixed blade will serve you well. For a decent fixed blade at a decent price try a Buck Hunter. It holds a good edge and not too big.A Leatherman/knock off give you a little flexability for everyday life and a good fixed blade can cut, chop or be strapped to a shaft as a spear.
