<p>A hair trimmer includes a cutting head 20 with an outer shearing foil 21 and an inner cutter 30 in hair shearing engagement with the shearing foil 21. The cutting head 20 is characterizee to have a hair guide surface 24 on its top and a skin engaging comb 40 for contact with the skin of the user. A number of hair introducing perforations 22 are formed in a portion 25 of the outer shearing foil 21 which is located below the hair guide surface 24 and extends in an inclined relation with respect thereto. The cutting head 20 is adapted in use to be advanced along the hair strands toward the tips thereof with the skin engaging comb 40 ahead of the hair guide surface 24. During this movement, the hair strands are combed into between the hair guide surface 24 and the skin and are then flexed outwardly upon leaving the hair guide surface 24 such that the tips of the hair strands are fed ito the perforations 22 in the inclined portion 25 behind the hair guide surface 24 in the advancing direction of the cutter head. Thus, the tips of the hair strands are captured by the perforations 22 due to their flexing back action while they are generally moving away therefrom, whereby effecting the shearing the hair strands only at their tips to provide a neat trimming finish.</p> |
