All around survival knife

My idea of the perfect all around survival knife would be a plain 12 inch machete. It's small and light enough to carry easily, cheap and available just about anywhere, and is far more versatile that most of the so-called "survival/tactical" knives selling for hundreds of dollars more.
You can cot, chop, hammer, scrape, and dig with it, and even use it as a weapon if the need should arise.
A 12 inch machete, in combination with a Leatherman Wave or Supertool, should handle just about anything that you would be likely to run into in a survival situation.
