If I could Only have one knife for the End of the World...

Talk about a nightmare...

Only one? You've got to be kidding. Still, fair enough question.
What if? What if you have to leave, on foot, not knowing where you are going and what will happen to you next. Not knowing if that knife will be used to defend yourself, build a shelter, fire, cut a hole through a wall/car/boat to escape, prepare food, carve wood, gut game, eat your dinner. And what if that's the only knife you'll have for the rest of your life?
A bit of a less painfull thought, lets make it three.

These are the three I'd go for. Busse Bushwacker Battle Mistress. Dog Soldier 8 and Leatherman Wave (Black oxide) although my Charge tti is a slightly better option.
Forced to chose just one? Dog Soldier 8. Big enough, small enough. The goldielocks size for a do it all knife with the right blade steel, geometry, finish and the right grip shape and material.
More of a tight budget proposition?

Cold Steel Bowie machete $24.40, Glock Survival knife $28.79 and Leatherman Sidekick $55.95. For little over a hundred bucks you have a setup to deal with everything knife related.
Forced to chose one? You cant go wrong with the Glock knife. Like the pistol, Its a beast of a knife yet light and well priced.
