FINE PINK STONES. We designed them to polish and de-burr like no other stone available to ski tuners. They are truly unique in their function. And like all of our stones, they can be re-dressed over and over again. If you are only going to buy one polishing stone, make sure it is the ceramic.
We refer to them as the "mop" because of their uncanny ability to find and remove every trace of a burr. It just mops them up. Burrs are the prime enemy of all tuners; this stone is simply a no-brainer when it comes to de-burring a ski. And, they leave edge metal polished and with great glide.
