ABSTRACT:
A device and a method for contouring an ice skate blade. The method comprises the steps of measuring the overall length of the soleplate of the boot and calculating the center point of the soleplate, transferring the center point of the soleplate to the blade and marking the center point of the soleplate onto the blade as the first calibration point. A second and third calibration point, calculated as 25% of the soleplate length are marked from the first calibration point towards the toe and towards the heel of the blade. Toe and heel radius termination points are also marked. The device comprises a measuring tool for measuring the length of the soleplate and having calibration points and radii termination points preset on the device according to the soleplate length. The device therefore eliminates the calculation of all the calibration points and radii termination points each time an ice skate blade is to be contoured. The blade depths at the second and third calibration points are measured and the needed pitching is determined. The blade is ground based on the calibration points with some adjustments for the skate wearer's physique and skill level.
