Abstract
A method of, and apparatus for, treating an elongate rotary tool (22) that presents a sharp cutting edge (30) are described. The method includes the steps of emitting under pressure from a nozzle (60) an abrasive fluid stream comprising an abrasive grit entrained in a fluid;
and impinging the abrasive fluid stream against the sharp cutting edge (30) of the elongate rotary tool (22) for a preselected time so as to transform the sharp cutting edge (30) into a relatively uniformly honed edge. The apparatus (50) includes a rotatable fixture (54) that releasably holds the elongate rotary tool (22). A nozzle (60) that emits under pressure an abrasive steam. The nozzle (60) and the elongate rotary tool (22) are relatively moveable so that the abrasive stream impinges the entire length of the sharp cutting edge (30).
