Abstract
Abstract A racket for tennis and like games which includes a handle having a substantially oval cross-section, with two flat opposite planar surfaces of dimension such that the grasp of the hand on the racket is more accurately aligned to control the orientation of the plane of the head than is the case with existing rackets. The handle may be constructed to receive a rigid hollow grip portion so that the grip portion may be quickly replaceable to change grip size or surface characteristics.
