re: BWL & Bill D,
Posidrive (star or double cross shaped) is not another term for phillips - why not filips, btw? - (cross shaped) head. But many a handyman (in Europe as well) has not noticed the difference between these two, and thus keeps screwing up the (srew)heads using the wrong one.
I understand that pzd is considered to be somehow more suitable for "makitaing"; at least here in Finland only the plaster board and tin-sheet screws are Phillips headed any more.

AKS, who happens to own an AEG makita, and is planning to join the I-dremelled-it-myself society someday ;-)

p.s. back in the 70s we used to have araldite, too, but then some of us shifted to super epoxy ...
