ABSTRACT:
A mechanism for the sharpening of skate blades comprising a small cylindrical honing stone or similar device, supported and located by two rollers which are caused to rotate, thus rotating the stone as this slides back and forth along the concavity of the blade. This results in sharpening the edges and forming a concavity of a suitable radius. A means of tilting the stone to maintain this tangent to the curvature of the blade, is also achieved such that the total cylindrical surface of the cutting (honing) stone is utilized.
