When I was learning to service a number of foreign-made machines, we were
told that the metric + screwdrivers were sharper than the American ones. We
called them ALL Phillips screwdrivers. There is probably a lot more to the
answer than this.

What do you call a drink made from milk of magnesia and vodka? Ans.--a
Phillips screwdriver.
