> A Swiss Army knife does a bunch of things, all of them poorly.
Counterexample: the Phillips head screwdriver in my Swiss Army knife is actually the best Phillips head I've ever found. It can easily turn without slipping a wider range of screw head diameters and depths than any other screwdriver I've used.
(Does anyone else have way more screwdrivers around than they can explain? I cannot think of any reason I would own more than two or three full sized screw drivers, and one set of small of jewelers screwdrivers...but I've got more than a dozen full sized ones and a couple sets of jewelers screwdrivers. I cannot remember buying, inheriting, finding, stealing, borrowing and not returning, or being gifted any of them--but there they are. Glitch in the matrix?)
