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.

11. The skate blade grinding system of claim 10 , wherein the movement of the first jaw and the second jaw along the first, second, and third angled slots from the unclamped position to the clamped position is configured to translate the first jaw and the second jaw toward each other and toward the actuating mechanism.
12. The skate blade grinding system of claim 1 , wherein the second jaw is configured to pivot about the third fastener.
13. The skate blade grinding system of claim 1 , wherein each of the first fastener, the second fastener, and the third fastener include a flanged bearing.
14. The skate blade grinding system of claim 1 , wherein the third opening is positioned between the first opening and the second opening, and wherein the positioning of the first opening, the second opening, and the third opening form a triangle.
15. The skate blade grinding system of claim 1 , wherein each of the first jaw and the second jaw comprise at least one accessory opening, wherein the at least one accessory opening is configured to interface with a removable accessory.
16. The skate blade grinding system of claim 15 , wherein the removable accessory is configured to modify a position of the skate blade positioned within the skate blade clamping mechanism.
17. The skate blade grinding system of claim 15 , wherein the removable accessory is a riser configured to elevate an abutment surface of the skate blade.
