| 1. A method for manufacturing microabraders by machining a surface of a workpiece, each of the microabraders having a plurality
of sides, for each of the microabraders the method comprising:
(a) making a plurality of cuts into the surface, the plurality of cuts being in a required sequence around the plurality of
sides to form a microabrader of a required shape;
(b) the plurality of cuts being of progressively reducing depth of cut such that a final cut is of a smallest depth of cut
of all the cuts.
