1. A method for contouring an ice skate blade of an ice skate, the ice skate having a soleplate, the ice skate blade having a toe, a heel, and a center portion disposed between the toe and the heel, the method comprising the following stepsmeasuring the overall length of the soleplate of the ice skate,calculating the center point of the soleplate and transferring the center point of the soleplate to the blade,marking the center point of the soleplate on the skate blade as a first calibration point,calculating a second and third calibration points as 25% of the overall length of the soleplate,marking the second calibration point on the blade from the first calibration point towards the toe of the blade, marking the second calibration point on the blade from the first calibration point towards the heel of the blade,marking a toe radius point closer to the toe than to the second calibration point;

  • marking a heel radius point closer to the heel than to the third calibration point;

    measuring the depth of the blade at the second calibration point and at the third calibration point,determining the pitch requirement of the blade from the variation in blade depth at the second and third calibration points,grinding a first radius curve, the work center radius curve about the first calibration point towards the toe and towards the heel, the work center radius curve having a specific radius,pitching the blade towards the toe,grinding a second radius curve, the front radius curve on the blade from the toe towards the work center radius curve, andgrinding a third radius curve, the back radius curve from the heel of the blade towards the work center radius curve.
