Abstract
To minimize the risk for injuries due to hooked hair catching teeth, but still have a reasonable hair-cutting efficiency, a cutting unit for a hair-cutting device having two blades moving relatively to each other with at least one of the blades being toothed is proposed, wherein at least some teeth have a larger cross-sectional area at their free end than at their end making the junction with the blade, wherein the larger cross-sectional area is 0.3 mmor more and wherein the shape of the larger cross-sectional area is such that the tooth surface oriented to face the surface with hair to be cut when cutting has a larger distance to the middle axis than the equivalent surface of the blade-side-end.
