A method for producing round stock () which is provided with at least one inscription and/or marking (), at least the surface () of the round stock () consisting of a metallic material, in particular of chromium or steel, for example of hardened steel, chromium-plated steel or stainless steel. In order to improve this method such that disadvantages and shortcomings are avoided, the method includes the following steps: placing on the surface () at least one cover () which is adapted to the shape of the surface () and in particular has the inscription and/or marking (), such that the region to be provided with the inscription and/or marking () is not covered by the cover (),&#x2014;exposing the round stock () to a first electrolyte () together with the cover (), material being removed from the surface () by said electrolyte in the region to be provided with the inscription and/or the marking () while producing depressions (), and&#x2014;exposing the round stock () together with the cover () and the depressions () not covered by the cover () to a second electrolyte () by which the depressions () are filled to produce the inscription and/or marking () which differs from the surface () optically, in particular with respect to color. The present invention also relates to round stock () which is manufactured from a metallic material, with the round stock being provided with a correspondingly produced inscription and/or marking ().
