Another great reason to have either vice-grips or some other sort of locking pliers (with cutter), is the ability to "harvest" wire. Suppose you forgot to add a coat hanger, but found an old pile of barbed wire. With 5 inch vice-grips it's an easy matter to cut off enough wire, and then bend it, to make a nice cooking grill. Or, untwisted and with the barbs removed, you have 2 pieces of wire that are even tougher than a coat hanger.
I guess the above is dependent on where you did your "surviving". Up here it's cow country, and anywhere you have cows there's always LOTS of barbed wire around, even way back in the sticks. A second pair of pliers, to help hold and make the bends, would also be handy, which is where the Sebertool would come in handy. While the handles are short, it's still a pretty robust tool.
