Abstract
The invention is an improved sports racket comprising streamlined transversal strings and streamlined longitudinal strings with surface indentations that permit the strings to lock into each other at the string crossings so the strings do not move with respect to each other and also stay oriented so as to minimize wind resitance during the swinging motion of the sports racket before and after ball contact. The invention includes fixing means for assembly of the strings in the sports racket.
