Abstract: A hair cutting machine (10) having a handle (12) that contains an electromotive drive unit (49) and having a cutter head (16) that is disposed at the front handle end and, in the operating position of the handle (12), has a stationary blade (18) and an oscillating blade (20) disposed above it, the stationary and oscillating blades (18, 20) forming a cutting plane (22) that lies between the two blades (18, 20) and is inclined in relation to the longitudinal axis (24) of the handle (12). In the operating position of the handle (12), the cutting plane (22) is inclined downward in relation to the longitudinal axis (24) of the handle (12) and the oscillating blade (20) is disposed above the stationary blade (18), which makes it possible to produce a haircut that is comparable to a classic scissors cut (FIG. 9).

Abstract: A bladeset for a hair clipper includes at least one stationary blade having a plurality of stationary blade teeth, and at least one moving blade having a plurality of moving blade teeth and being configured for laterally reciprocating relative to the at least one stationary blade for cutting hair therebetween, the moving blade having a set of long teeth configured for cutting hair across a width of said moving blade, and a set of short teeth configured for cutting hair across said moving blade width when a clipper feed rate exceeds a given speed.
