1. A method of sharpening an ice blade comprising the steps of:
placing said ice blade in a holder;
using a non-contact 3D scanner to measure a three-dimensional (3D) shape of an ice contacting surface of said ice blade in said holder;
comparing said measured 3D shape to a desired sharpened 3D shape for said ice blade to identify differences between said measured 3D shape and said desired sharpened 3D shape;
sharpening said ice contacting surface of said ice blade in said holder to remove from said measured 3D shape said differences with said desired sharpened 3D shape, and prior to said sharpening step, evaluating said measured 3D shape of said ice blade to determine if said ice blade is too worn for said sharpening step; and
re-using said 3D scanner to re-measure said 3D shape of said ice contacting surface of said ice blade in said holder after said sharpening step to ensure said sharpened ice blade conforms to said desired sharpened 3D shape.
