Tektronix used Pozidriv screws exclusively for many years, until they
converted over to Torx. A standard Phillips bit fits poorly in a Pozidriv
screw, making it really easy to chew up the screw with this combination.

How well does it work the other way around -- using Pozidriv screwdrivers on
"regular old" Phillips-head screws?
