Abstract
A blade set for a hair cutting appliance is described. The blade set (26) is arranged to be moved through hair in a moving direction to cut hair, and includes a stationary blade including a support insert and a metal component. The metal component and the support insert are force-fitted to one another. The metal component is at least sectionally deformed to define at least one toothed leading edge having double-walled stationary blade teeth. The metal component forms a first wall that is arranged to serve as a skin-facing wall when in operation, and a second wall that is facing away from the first wall. A guide slot for a movable blade is defined between inwardly facing inner surfaces of the metal component and the support insert and a movable blade having a plurality of movable blade teeth.
