Blade set, hair cutting appliance, and related manufacturing method

A method of manufacturing a metal-plastic composite stationary blade of a blade set for a hair cutting appliance, comprising the following steps:

• providing a metal component, particularly a sheet metal component, at least substantially forming a central portion of a first wall portion,
• providing a mold, particularly an injection mold, the mold defining a shape of a plastic component,
• arranging the metal component in the mold,
• providing a substitute component in the mold, the substitute component being configured to keep clear a to-be-formed guide slot of the stationary blade when molding,
• forming, particularly injection molding, the plastic component,
• wherein the plastic component and the metal component define a first wall portion and a second wall portion, the first wall portion being arranged to serve as a skin facing wall when in operation, the second wall portion being at least partially offset from the first wall portion, such that the first wall portion and the second wall portion define therebetween the guide slot for a movable cutting blade,
• wherein the first wall portion and the second wall portion jointly form at least one toothed leading edge comprising a plurality of teeth, and
• wherein the first wall portion and the second wall portion are connected at a frontal end of the at least one leading edge, thereby forming tips of the teeth, and
• removing the substitute component from the metal-plastic composite stationary blade.
