Abstract
A screwdriver for resisting premature disengagement of a screw from the screwdriver. The screwdriver includes a shaft having a central axis; a tip radially aligned with the central axis of the shaft which includes an end opposite the shaft, at least one radial protrusion extending away from the central axis, and a notch; and a screw retention mechanism including a flexible member aligned with the notch and attached to either the tip or the shaft. The flexible member has an unattached end which is separated from the second end of the tip. When the tip is inserted into a recess of a screw, the flexible member flexes toward the central axis and creates an opposing elastic force which holds the screw to the tip.
