Abstract
A rasp blade has cutting teeth arranged along the outer perimeter of the blade and having a variable radius. The radius is raised for the teeth at either end of the blade. The radius is lower for the teeth at the center of the blade The radius variation is determined by the rasp blade cutting diameter and the angle that the blade is to nest on the end plate of the hub assembly in which the blade is used. The blade may extend from 30° to 90° with the preferred sizes being 45° or 90°. At least three apertures are provided in each blade to ensure that the failure of any one pin holding the blade in the hub assembly does not result in catastrophic damage to the hub assembly.
