Rollerski tips become dull with use! You want to ski with sharp tips both to prevent slippage (and possible injury), and to allow you to confidently ski with good technique. To avoid rollerskiing with dull tips sharpen them before each use.
The Diamond View Disc attaches to a drill and effectively and quickly sharpens your rollerski tips.
Diamond View Disc coarse/fine TIN 110mm w/9mm axle. The Diamond View Disc has a diamond-grit surface on both sides, the one coarse, the other fine, and is titanium reinforced. The titanium extends the life of the diamond-grit surface and reduces “carbon diffusion” when grinding/sharpening steel. Friction under use is reduced which in turn reduces the total heat generated on your rollerski tips, thus extending the longevity of the tips.
