A blade set for a hair cutting appliance, said blade set being arranged to be moved through hair in a moving direction to cut hair, said blade set comprising: a segmented stationary blade comprising: - a first wall portion arranged to serve as a skin facing wall portion during operation, a second wall portion, and an intermediate wall portion, at least the first wall portion and the intermediate wall portion extending in a substantially flat manner, wherein the first wall portion, the second wall portion, and the intermediate wall portion are fixedly interconnected, thereby forming a segmented stack, wherein the intermediate wall portion comprises at least one cutout portion and is disposed between the first wall portion and the second wall portion, wherein the first wall portion, the second wall portion, and the intermediate wall portion jointly form, at an end of the segmented stack, at least one U-shaped toothed leading edge (32, 34), wherein the toothed leading edge (32, 34) at least partially extends in a transverse direction (Y, t) relative to the moving direction assumed during operation, wherein the intermediate wall portion forms, at the at least one toothed leading edge (32, 34), a filled portion that connects the first wall portion and the second wall portion at the at least one toothed leading edge (32, 34), wherein the toothed leading edge (32, 34) comprises a plurality of mutually spaced apart projections alternating with respective slots, thereby defining a plurality of U-shaped teeth and respective tooth spaces, wherein the mutually spaced apart projections at least partially extend forwardly in a longitudinal direction (X, r) approximately perpendicular to the transverse direction (Y, t), wherein the first wall portion, the second wall portion and the at least one cutout portion in the intermediate wall portion define therebetween a guide slot for an insertable movable blade, and wherein the guide slot comprises a vertical clearance height dimension (t cl) that is larger than an expected vertical thickness dimension (t m) of a to-be-mounted movable blade, wherein the vertical clearance height dimension (t cl) is selected such that a resulting assembly clearance height dimension (t rcl) provides for a defined clearance fit mating of the to-be-mounted movable blade in the guide slot; and a movable blade with at least one toothed leading edge (106, 108), said movable blade being movably arranged within the guide slot defined by the stationary blade, such that, upon lateral motion or rotation of the movable blade relative to the stationary blade, the at least one toothed leading edge (106, 108) of the movable blade cooperates with corresponding teeth of the stationary blade to enable cutting of hair caught therebetween in a cutting action. a segmented stationary blade comprising: - a first wall portion arranged to serve as a skin facing wall portion during operation, a second wall portion, and an intermediate wall portion, at least the first wall portion and the intermediate wall portion extending in a substantially flat manner, - a first wall portion arranged to serve as a skin facing wall portion during operation, a second wall portion, and an intermediate wall portion, at least the first wall portion and the intermediate wall portion extending in a substantially flat manner, wherein the first wall portion, the second wall portion, and the intermediate wall portion are fixedly interconnected, thereby forming a segmented stack, wherein the intermediate wall portion comprises at least one cutout portion and is disposed between the first wall portion and the second wall portion, wherein the first wall portion, the second wall portion, and the intermediate wall portion jointly form, at an end of the segmented stack, at least one U-shaped toothed leading edge (32, 34), wherein the toothed leading edge (32, 34) at least partially extends in a transverse direction (Y, t) relative to the moving direction assumed during operation, wherein the intermediate wall portion forms, at the at least one toothed leading edge (32, 34), a filled portion that connects the first wall portion and the second wall portion at the at least one toothed leading edge (32, 34), wherein the toothed leading edge (32, 34) comprises a plurality of mutually spaced apart projections alternating with respective slots, thereby defining a plurality of U-shaped teeth and respective tooth spaces, wherein the mutually spaced apart projections at least partially extend forwardly in a longitudinal direction (X, r) approximately perpendicular to the transverse direction (Y, t), wherein the first wall portion, the second wall portion and the at least one cutout portion in the intermediate wall portion define therebetween a guide slot for an insertable movable blade, and wherein the guide slot comprises a vertical clearance height dimension (t cl) that is larger than an expected vertical thickness dimension (t m) of a to-be-mounted movable blade, wherein the vertical clearance height dimension (t cl) is selected such that a resulting assembly clearance height dimension (t rcl) provides for a defined clearance fit mating of the to-be-mounted movable blade in the guide slot; and a movable blade with at least one toothed leading edge (106, 108), said movable blade being movably arranged within the guide slot defined by the stationary blade, such that, upon lateral motion or rotation of the movable blade relative to the stationary blade, the at least one toothed leading edge (106, 108) of the movable blade cooperates with corresponding teeth of the stationary blade to enable cutting of hair caught therebetween in a cutting action.
