Unlike existing skate sharpening machines, the Sparx Sharpener doesn't require re-alignment with every pair of skates sharpened and there’s no need to realign the machine when swapping out Grinding Rings or sharpening skates with different blade thicknesses. Alignment of the Sparx Sharpener is typically performed during initial set up and then checked periodically over time.

A simplified user interface allows the Sparx Sharpener to be intuitive - adjust number of sharpening cycles, monitor the life of your Grinding Ring, receive safety alerts, and sharpen - all from the easy-to-use control pad. The custom electronics continuously controls and monitors all sharpening functions to ensure an accurate and safe sharpening.

Our patented skate clamp design perfectly aligns the skate to the grinding ring, eliminating the challenges posed by varying blade types and thicknesses. Simply depress the clamp lever, insert the skate into the skate clamp and you’re ready to go. No need to line up the skate blade with the grinding ring – the self-centering skate clamp takes the guesswork out of achieving a perfect sharpening every time.

The Carriage moves the Grinding Ring across the skate blade with consistent pressure, translation speed, and RPM. This unparalleled consistency ensures a smooth surface finish every time and the consistent pressure and speed preserves the blade’s profile/rocker for the life of the blade, unlike traditional sharpeners that alter profiles after just a few sharpenings.

Dust accumulation is inevitable when sharpening skates, but we have you covered. The Sparx Sharpener features an integrated filter system and powerful fan that collects and filters out dust particles, allowing your sharpener – and surroundings – to remain clean. The advanced electronics automatically notifies you when its time to change your filter.

A simple, easy-to-use adjustable ring arbor allows for on-the-fly adjustments for short or tall steel. Our patented Height Adjustment Knob is easily located within the sharpener and is simply turned left to raise the height of the ring, or turned right to lower the height. Go from one pair of skates with high steel to another with low steel in just a matter of seconds.
