Correct Screwdriver:

Just for future reference, the Brownells set and the extra thin blade set will handle most situations. Dan Rositter advised me to get a couple sets of the Grace hollow ground with the wooden handles. He said use one as is and if you need a special width driver to grind one from the second set on a drill press with a hard Dremel stone. It works slicker than goose dookie.
