The Bont short track ceramic sharpening stone is designed with the professional short-track skater in mind but is suitable for anyone looking for the perfect edge. The grit is 8000. This stone should be used as your final polishing stone while sharpening your short track blades. Polishing stones help you to increase your glide while skating. This ceramic sharpening stone is made using exceptionally high-grade material, resulting in a sharpening stone that is extremely uniform, meaning the abrasive encountered with the first month of use will be the same after years of use. When sharpening knives, a perfectly flat stone is not as important as when sharpening speed skate blades because you are sharpening both blades at the same time so it is very important that a stone made for sharpening short track blades is perfectly flat. It is also important to have a stone thick enough to hold while you sharpen your skates. The Bont Ceramic stone is thicker than many knife sharpening stones for this reason. Key features: Perfectly flat surface 8000 grit designed for short track speed skaters Easy to hold while sharpening blades Size: 300mm x 60mm x 15mm
