ABSTRACT:
A racket is described, with a center of gravity thereof being approximate to a center of a rubber sheet of the racket, and a center of gravity that moves approximately to the center of rubber sheet and is located in a high ball-strike area. The racket has a substantially triangular blade. The blade comprises a head, a neck and a handle. The head becomes gradually narrower from front to back of the head, and the handle can further be lightened. The center of gravity of the racket can thereby move forward to the center of the rubber sheet to enhance attack and defense abilities of the racket, and reduce shock.
