Spiky Shark is the first spin-oriented string that is designed from the bottom up with specific new material and profile matched up for perfection. Spiky Shark foundations began with more than ten Years of know-how from Super Smash spiky with its diagonal surface structure (The US patented spiky points used in Long Life, Spiky and Hybrix Spin string). Powerful and precise and playable compounds made of Co-Polyamides like Pro Line II and Competition were fine tuned and an unique octagonal parallel profile developed to give optimum grip to the ball to ensure the best slice and spin transfer while overcoming string stiffness.
