Screwdriver
 A screwdriver is provided with a handle which includes a wheel member and a head member. The wheel member is formed about the upper portion of the shank of the screwdriver and is anchored to rotate therewith. The head member is mounted by ball bearing assemblies to bear against the upper end of the shank and the wheel member. This enables the palm of the hand of the user to exert a downward pressure on the stationary head member to hold the wedged shaped end of the shank in a slot on a screw head while the fingers of the hand can be used to manipulate the rotation of the wheel member to thereby rotate the shank to drive the screw.
