Method for machining steel edges for skis or the like, the steel edge being at least partly rapidly heated, then rapidly cooled again and consequently hardened with the aid of a plasma jet. In order to provide a method, which in economic manner can ensure the uniform and precisely defined hardening of steel edges of skis and the like in a randomly long longitudinal portion and in which simultaneously the energy can be applied in a more gentle and planned manner and a less complicated guidance of the plasma jet is rendered possible, an electric arc is produced between the cathode and the anode of the plasma head and a gas flow is passed through said arc and the anode of the plasma head, accompanied by the production of a plasma jet and the steel edge to be hardened is electrically connected as an anode in synchronized manner with the plasma head anode, i.e. is also polarized as an anode, or alternatively only the steel edge is polarized as an anode, an electric arc is produced between the steel edge and the cathode of a plasma head and a gas is passed through said arc, accompanied by the production of a plasma jet directed onto the steel edge.
