ABSTRACT:
A method of, and apparatus for, treating an elongate rotary tool that presents a sharp cutting edge are described. The method includes the steps of emitting under pressure from a nozzle an abrasive fluid stream comprising an abrasive grit entrained in a fluid; and impinging the abrasive fluid stream against the sharp cutting edge of the elongate rotary tool for a preselected time so as to transform the sharp cutting edge into a relatively uniformly honed edge. The apparatus includes a rotatable fixture that releasably holds the elongate rotary tool. A nozzle that emits under pressure an abrasive steam. The nozzle and the elongate rotary tool are relatively moveable so that the abrasive stream impinges the entire length of the sharp cutting edge.
