Abstract
A racketball racket comprises a metal frame in the form of a single strip of metal of substantially uniform cross-section bent intermedially to provide a head portion that defines the striking area and merges through a reversely curved throat portion to side by side ends for providing a handle portion and a rigid throat piece element extending across said frame at the throat portion and defining the inner margin of said striking area. The opposite ends of the throat element are attached to said strip at said throat portion by tongue and slot connection regions wherein the lateral flexibility of the frame is maintained substantially the same as in other parts of the frame in the head portion. In making the racket the string receiving holes in the head and the slots for mounting the throat piece element are formed in the strip after it has been bent to the condition it assumes in the final assembly.
