Skate blade sharpening system
A skate blade grinding system used to sharpen and profile the blades of ice skates. The skate blade grinding system can include a housing that includes an elongated slot for receiving the blade of an ice skate for sharpening, and clamp jaws for retaining the skate. The skate blade grinding system can automatically operate a grinding wheel and move the rotating grinding wheel back and forth along the lower face of the skate blade to grind the skate blade.
