Extra fine diamond grindstone, grain #1000. 100mm with a new larger grinding surface. Grindstone for finishing the edges when a mirror-like finish is required. Used particularly in speed disciplines for optimum cutting precision.
Fine diamond grindstone, grade #600. 100 mm with a new larger grinding surface. For final polishing steel edges after filing. Helps keep edges sharper for longer.
Medium diamond grindstone, grade #400. 100mm with a new larger grinding surface. This is the second grindstone you must have to maintain sharp and precise edges. With this grindstone, you can give the edge a fine polishing gloss.
Coarse diamond grindstone, grade #200. 100mm with a new larger grinding surface. Used to bevel and tune sharp and precise edges on alpine skis and snowboards. This is one of the two grindstones that can do “everything” within this category.
Extra-coarse diamond grindstone, grade #100. 100mm with a new larger grinding surface. This grindstone is used to bevel and tune the edges of alpine skis and snowboards. It removes hardened steel after the edge has hit stones or rocks. After the ski edge has been initially set in the production process at the factory, the tip and rear end have the same type of over-hardened surface, which is easily beveled using this grindstone.
