ABSTRACT:
A screwdriver including a relatively large teardrop-shaped, hollow handle, comfortable to the hand for delivering increased turning power, is provided with a self-contained ratchet mechanism which, in turn, has a three-position ratchet control (forward, reverse and lock). The shank of the screwdriver houses a magnet for releasably holding any one of a number of bits in place during use. The handle has a series of finger-engageable projections on its stem to assist the operator in applying torque and for storage of bits therein. A retainer ring on the stem holds the bits in the chambers until indexed to a bit-releasing position.
