The Neottec Katana's elastic surface gives it a gentle touch, with a good amount of spin and precision. These attributes give the player looping power, and control of the short game. The medium soft elastic sponge used with this rubber will give spin strokes more direct power. This rubber comes with three sponge thicknesses: 1.8 mm, 2.0 mm, 2.1 mm.
Using the thin sponge give the player control over the stroke, while the thicker sponge will provide more speed and spin potential. The thicker the sponge is, the heavier the racket will be.
