Whether you're looking for more bite or glide, the Bauer ProSharp machine offers a range of blade hollows to help optimize your on-ice performance. There are two types of wheels you will use when sharpening your skates: Hollow Grinding Wheels and Flat Grinding Wheels.

Hollow Grinding Wheels are used to sharpen your steel to your favorite radius of hollow. If you're unsure which hollow to start with, it's recommended using a 3/4" wheel as a baseline. From there, you can try different wheels to find which hollow suits your style of play best.

Flat Grinding Wheels are designed to "reset" your blade. This process is important when prepping new steel or refreshing your blade if you damage your edges.

On average, a grinding wheel will sharpen about 75 pairs of skates. Your ProSharp Bauer AdvantEdge Skate Sharpener will notify you when it's time to replace your grinding wheel.
