Abstract

Abstract A racket handle for a racket includes grooves for positioning a player's fingers in a position specifically adapted to the stroke to be performed, and to increase the contact surface between the player's fingers and the racket handle while also assisting the player in teaming a correct grip and stroke. In one embodiment, three index finger grooves are provided in from of a thumb groove. Each index finger groove corresponds to a position of the index finger during a different type of stroke, such as a forehand stroke, a volleying stroke, and a backhand stroke. The thumb groove is also positioned obliquely opposite and adjacent to a middle finger groove to permit the thumb and middle finger to be in contact with one another to form a lock ring around the racket handle.
