Kirschbaum Black Shark 125 17g Tennis 12M String Set

Featuring an octagonal shape to enhance spin potential, it’s perfect for baseliners looking to add spin and control to their game. This string is the shaped version of the Pro Line II, while maintaining its impressive precision and feel characteristics. Many players use this string as a hybrid, combining it with a softer, more powerful string on crosses. 

Building upon the immense experience that Super Smash Spiky gave us, we develop an absolutely innovative string like that one in its moment. The upstanding characteristics are its eight-dented profile that transfers a tremendous spin to the ball retaining a great playability. We are sure that Black Shark will give as much satisfaction as Super Smash Spiky gave us. Why the name Shark? Because of the shape of its teeth that bites the ball like a shark.
