ABSTRACT:
A bulbous hand grip facilitates the turning of a key within a lock by increasing the turning radius through which the key is turned, as well as providing finger and hand surfaces which may be utilized during turning. The hand grip may include a substantially arcuate or spheroidal surface contour. The key may be secured within the hand grip by elastic deformation forces and/or by conventional fasteners.
