Hair trimmer device with comb unit

To allow trimming body hair by pulling as well as pushing with the same hair trimmer device, its comb unit is positioned over the trimming head in at least two different positions, one pulling and one pushing position. In particular, in the different comb positions, the tips of the comb unit's fins point in the direction of the respective movement. Preferably, the comb unit is removably attached. In a preferred embodiment, the trimming head includes shaving means besides trimming means.
