The first transverse edge portion and the second transverse edge portion are beveled from the middle portion to the respective edges of the stationary blade. The stationary blade is symmetric about a midline of the middle portion. In some embodiments, the trimmer includes a toothed blade guard.

A stationary blade for a blade set of a hair cutting appliance includes a top wall, a bottom wall, and a guide slot formed between the top and bottom walls to accommodate a movable blade. The stationary blade further includes a plurality of stationary blade teeth each having a frontal end. The top and bottom walls are mutually joined at the frontal ends, where the top and bottom walls are, at least at the frontal ends, made from sheet metal material. Further, at the frontal ends, two or more sheet metal folded edges are present.

A stationary blade for a blade set of a hair cutting appliance is described. The stationary blade is arranged to be moved through hair in a moving direction to cut hair. The stationary blade includes: 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; and at least one toothed leading edge comprising a plurality of teeth and being jointly provided by the first wall portion and the second wall portion. The first wall portion and the second wall portion are connected at a frontal end of the at least one toothed leading edge to provide tips of the teeth. A blade set including the stationary blade and a moveable cutting blade are also described. A method of fabricating a blade set is also described.

A hair clipper is provided, including a chassis having upper and lower chassis portions defining an enclosed interior chamber, said upper and lower chassis portions configured for being secured together; and an outer housing including upper and lower housing portions constructed and arranged for enclosing the chassis as the housing portions are secured together such that the interior chamber is isolated from the housing.

The present disclosure relates to a method of manufacturing a stationary blade (102) and to a stationary blade (102), the method comprising providing a metal component (106), involving applying a first bending procedure, thereby forming a top wall (112) and two legs (114, 116) at opposite ends of the top wall (112) that are spaced away from one another in a longitudinal direction, wherein, subsequent to the bending procedure, each of the two legs (114, 116) is arranged at a first angle (α) with respect to the top wall (112), and wherein two bending edges (152, 154) are formed between the top wall (112) and the two legs (114, 116), providing a support insert (108) having a longitudinal extension (l.sub.s) that is at least slightly greater than a receiving space (l.sub.b) between the two bending edges (152, 154), joining the metal component (106) and the support insert (108), wherein the metal component (106) is at least slightly pretensioned due to the longitudinal extension (l.sub.s) of the support insert (108), and applying a second bending procedure to the metal component (106), comprising further bending the two legs (114, 116), thereby arranging each of the two legs (114, 116) at a second angle (*) with respect to the top wall (112) that is smaller than the first angle (α).

A blade set for a hair cutting appliance includes a stationary blade and a cutter blade. The stationary blade has a blade base and a plurality of teeth extending from the blade base in a longitudinal direction. The teeth are arranged in a series alternating with tooth gaps therebetween, where the tooth gaps define hair entry slots. The teeth have a first side arranged to cooperate with the cutter blade to cut hair and a second side arranged as a skin-facing side. The teeth have processing edges at the first side at their longitudinal extension, where the smoothened processing edges have smoothened edge transitions.

A device for treating body hair includes a host, a first functional component, and a second functional component. The first functional component is disposed at a first end of the host, and the second functional component is disposed at a second end of the host. The first functional component includes a knife blade and a knife blade notch, and the knife blade extends out of the first functional component from the knife blade notch. The second functional component includes a hair combing part and a heating body fixedly disposed in the hair combing part. The first functional component is movably disposed on the host, and the first functional component includes the knife blade for removing body hair, users may adjust a usage angle of the device as required.
