The grip portion of a tennis racket comprises a pair of flat surfaces disposed in parallel relationship relative to each other and relative to a flat plane containing the head of the racket. Each of the flat surfaces is subtended by an obtuse angle having its vertex at a geometric center of the grip portion. A pair of at least substantially arcuate surfaces are each subtended by an acute angle and intersect the flat surfaces to define four perceptible edges about the grip portion, with each of the arcuate surfaces being defined by a radius having its center at the geometric center of the grip portion and further having a length of about 0.75 inches.
