Kirschbaum Set Shark Tennis String
The Kirschbaum Spiky Shark is based on ten years of know how from the Super Smash Spiky with its diagonal surface structure. The new Spiky Shark is equipped with an octagonal teeth profile parallel to the string. Using a specially developed technique we accomplish peaks for an optimum grip at the ball to ensure the best slices and spin transfer. (US Patent 6117383) - SPIKY SHARK: a new meaning in spin transfer.
