What is the best tool to remove security (one way) screws from window
bars? The device I bought for $15 at Home Depot just slides off the
screws and is basically useless. (It sort of resembles a miniature lug
nut wrench with a little washing machine agitator inside. It is used
with a power drill.) Suggestions appreciated.

If you don't mind ruining the screw, a left-handed drill bit in a
reversible variable-speed electric drill does a good job.
