1. A method of trimming a sharp instrument having a sharpened edge, characterized in that it comprises : - emitting a laser beam (100) having a power density lying between 10**6 and 10**8 W/cm**2 , - focusing the laser beam (100) on the instrument edge whereby the axis of the laser beam (100) and the tangent to the instrument edge are substantially concurrent, and - moving the focusing spot of the laser beam (100) along the entire instrument edge at a set speed to melt the wire edge in the central region of the laser beam. |
