Swix Gummy Stone Blue/Extra Hard, One Size

Swix designed the Gummi Stone to remove nasty micro burrs that result after you sharpen your edges. Simply rub the Gummi Stone along the entire length of your ski or board's edge for a smooth finish. Or, just detune your tips and tails, which will reduce the chances of catching an edge, but will keep your side edges ultra-sharp for carving.
