A cylindrical shank has a first end affixed within the distal end of the handle. A socket member is removably coupled to a second end of the shank. A tool tip is removably coupled to the socket member. A dome shaped head is also provided. A joint is provided having a mechanism which permits the locking or swiveling the head on the proximal end of the handle. Accordingly when the head is permitted swivel relative motion is eliminated between the head and a palm of a hand gripping the handle by transferring the motion to the swiveling joint. The result is that friction, discomfort and blisters to the palm of the hand is thereby eliminated. Alternatively when the head is locked this allow user to apply more torque to the screw driver than when the head is permitted to swivel for situation which require extreme amount of force.
