Most of us "superusers" are regularly asked to fix computers for friends or family. To improve my chances of repairing a PC (or at least recovering important data) on the spot, I would like to assemble a portable kit of hardware and software tools that I can keep in my car.

What would you put in your "computer repair toolkit"?

One tool per answer please, so that the best tools can be voted to the top.
