Stationary blade, blade set, and hair cutting appliance

A stationary blade for a blade set of a hair cutting appliance, said stationary blade comprising:

• a first wall portion arranged at a top side of the blade, the top side being an outer side of the blade to serve as a skin facing wall during use;
• a second wall portion at a bottom side of the blade opposite the top side, 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 a guide slot for receiving a movable cutter blade of the blade set;
• and
• at least one toothed leading edge jointly formed by the first wall portion and the second wall portion and including teeth,
• wherein at least one tooth of the teeth has a first leg defined by the first wall portion and a second leg defined by the second wall portion, wherein the first leg has a cross section having a rectangular shape,
• wherein lateral sides of the second leg of the at least one tooth are arranged at an inclination angle (γ) with respect to a vertical plane perpendicular to the first wall portion, and
• wherein the inclination angle (γ) is from 1.5° to 45°.

• and
• at least one toothed leading edge jointly formed by the first wall portion and the second wall portion and including teeth,
• wherein at least one tooth of the teeth has a first leg defined by the first wall portion and a second leg defined by the second wall portion,
• wherein the first wall portion and the second wall portion are connected at a frontal end of the at least one toothed leading edge, thereby forming tips of the teeth including a tip of the at least one tooth, and
• wherein a cross section of the first leg at the first wall portion is rectangular, wherein the second leg is tapered in a direction away from the first leg, and wherein the first leg is larger in width than at least a bottom region of the second leg.
