Just like for girls, Diamonds are a skis best friend. Diamond stones such as the Swix X-Coarse Diamond Stone is perfect for deburring and sharpening your ski or snowboard edges. It works great for removing case hardening in the tip and tail from the grinding stone entry and exit of the ski at the manufacturing facility and hitting rocks. Swix Diamond Stones use a diamond fabric adhered to a flat, true aluminum piece to assure that there is no pressure rollover when sharpening side and base bevels. This special diamond cluster pattern will last longer than conventional strips and in conjunction with a polishing agent will help in removing the excess material from the edge to leave a clean, smooth mirror finish.
