ABSTRACT:
The present invention is directed to an apparatus for sharpening the blade of a skate which provides more precision that prior art sharpeners. The apparatus comprises a circular grindstone which can pivot from a work position to a rest or sharpening position. When in the rest position, the grindstone may be sharpened by a diamond, which diamond moves in circular motion when sharpening. The radius of curvature of the circular motion is selectable. The degree of concavity imparted to the blade is defined by curvature of the sharpening diamond. The blade is clamped in a slidable carriage while the grindstone, which is stationary with respect to the sliding motion of the carriage, follows the contour of the blade according to selected template. The blade clamp comprises two movable surfaces which properly center the blade with respect to the grindstone regardless of the blade's thickness.
