Tennis racket

A tennis racket comprising:

• a shaft and a substantially elliptical frame having top and opposite lateral portions and a shoulder at each lower end of said lateral portions converging into said shaft, said frame including a striking surface defined by interwoven strings;
• wherein said frame is formed with a plurality of transverse grooves at said top and lateral portions, the grooves extending from one face parallel with said striking surface, around the outside of said frame to the opposite face, the grooves terminating in stringing tubes;
• the frame further including a single longitudinal groove extending circumferentially at substantially a center line on the outside face of said frame from said shoulder at one of said lateral portions, crossing over all said transverse grooves to said shoulder at the other lateral portion and having series of central stringing holes passing through said frame from said outside to inside surfaces at the sections other than said top and opposite lateral portions, where said transverse grooves are not present, so that
• the string may pass through the grooves and stringing tubes so that the insertion point of the string through the frame is not always at the central portion of the frame.
