The method of the invention includes forming a plate and deforming, by ultrasonic forging, a plate side located between the conical surfaces (34, 35) of strikers (2, 3) for the purpose of forming a wedge- shaped edge on the plate (1) . The strikers are rotated around their longitudinal axes (Ll, L2) . The device of the invention is provided with a drive for rotating the strikers (2, 3) . On the working surface of the striker (2, 3) a recess is made, the generatrix of which corresponds to the form of the wedge-shaped edge surface . The invention enables to shorten the time of treatment and improve the quality of the cutting edge surface. |
