A blade set, the blade set comprising:
- a stationary blade comprising a first wall portion and a second wall portion integrally formed from a metal component and defining a guide slot, at least one first toothed leading edge, and a plastic component;
- a substitute component disposed in the guide slot of the stationary blade so as to occupy the guide slot during molding, the stationary blade being bent around the substitute component, thereby defining the guide slot,
- the stationary blade further comprising a frontal portion and a rear portion that after the bending, together define the second wall portion and are adjacent to each other,
- the substitute component being configured to be removed after molding to reveal the guide slot configured to receive a movable cutter blade, wherein:
- the first wall portion of the stationary blade is arranged to face skin when in operation, wherein the plastic component of the stationary blade is molded to the second wall portion and extends outward from the at least one toothed leading edge of the stationary blade thereby forming at least one tooth end of the plastic component, and wherein the plastic component comprises at least one mounting element.
