	My guess as to why a longer screwdriver will not
	jump out of the slot as easily is that the longer
	the shaft of the screwdriver, the less a lateral motion
	of the head will affect the angle that the tip makes
	with the slot.  This has the effect of steadying the
	unsteady hand, and keeping the screwdriver more in line
	with the screw.
