Sometimes a revolution comes in on little cats' feet
Witness the Phillips screw, featured on page 38 of the January 1936 issue of Popular Science Monthly.
"Screws and bolts with cross-shaped slots, and special screw drivers to take advantage of their non-skid, self-centering grip, are now obtainable. Screws of the new type may be guided home with positive control of direction, and may be poised on the tip of the driver for insertion in a hard-to-reach place."

Contrary to the description in the Popular Science Monthly write-up, Phillips head screws are decidedly NOT non-slip. Phillips head screws were engineered to limit the amount of torque that could be applied to the screw before the screw driver head slipped up and out of the slope-cut cross shaped slots.
