Blade set, hair cutting appliance, and related manufacturing method

An integrally formed metal-plastic composite stationary blade for a blade set of a hair cutting appliance, said blade set being arranged to be moved through hair in a moving direction to cut hair, said stationary blade comprising:

• a first wall portion arranged to serve as a skin facing wall when in operation,
• a second wall portion at least partially offset from the first wall portion, such that the first wall portion and the second wall portion define therebetween a guide slot arranged to receive a movable cutter blade,
• at least one toothed leading edge jointly formed by the first wall portion and the second wall portion, and
• a plastic component comprising at least one mounting element,
• wherein the at least one toothed leading edge comprises a plurality of teeth,
• wherein the first wall portion and the second wall portion are integrally made from a sheet metal component,
• wherein the first wall portion and the second wall portion mutually define an inner metal shell of the stationary blade,
• wherein the plastic component is molded to the second wall portion,
• wherein the teeth of the at least one toothed leading edge comprise, when viewed in a cross-sectional plane perpendicular to a lateral direction (Y), a substantially U-shaped form comprising a first leg at the first wall portion and a second leg at the second wall portion, wherein the first leg and the second leg merge into one another at respective tips of the first leg and the second leg,
• wherein the first leg, when viewed in a cross-sectional plane perpendicular to a longitudinal direction (X), comprises lateral cutting edges that are arranged to cooperate with respective cutting edges of the movable cutter blade, and wherein the second leg, when viewed in a cross-sectional plane perpendicular to the longitudinal direction (X), comprises a tapered portion at a top side, which side is the side facing the first wall portion, thereof, wherein the tapered portion is covered with plastic material of the plastic component.
