[[File:Frearson vs Phillips.svg|thumb|upright|Comparison of Phillips and Frearson screw heads]]
'''Reed and Prince''', also called '''Frearson''', is another historic cross-head screw configuration.  The cross in the screw head is sharper and less rounded than a Phillips, and the bit has 45° flukes and a sharper, pointed end.  Also, the Phillips screw slot is not as deep as the Reed and Prince slot.<ref>"The Phillips screwdriver has about 30° flukes and a blunt end, while the Reed and Prince has 45° flukes and a sharper, pointed end."
