摘要： A hair cutting appliance includes a stationary blade having a first wall portion arranged to serve as a skin facing wall when in operation; and a second wall portion offset from the first wall portion such that the first and second wall portions a guide slot that receives a movable cutter blade. A toothed leading edge is jointly formed by the first and second wall portions. Teeth at the toothed leading edge include a first leg defined by the first wall portion, and a second leg defined by the second wall portion. The first and second wall portions are connected at a frontal end of the toothed leading edge, thereby forming tips of the teeth. The second legs of the teeth are tapered along a portion of their longitudinal extension towards a bottom side of the stationary blade facing away from the skin, when in operation.
