Abstract (en)

[origin: WO03086719A1] A method for manufacturing a directionally dependent reflective surface on a substantially cylindrical body (1). The method comprising the engagement of a tool (4) with the outside surface (8) of the body, thereby forming at least one groove (23) therein with a cross section, when measured parallel to the longitudinal axis (2) of the body, that is asymmetric and wherein the groove is formed without removal of material from the body.
