Cutter system according to the preceding claim, wherein said additional part includes at least one spacer (15) defining said cutting air gap (25a, 25b) size, said spacer (15) being arranged adjacent to the second cutting element (5) and sandwiched together with the second cutting element (5) between the first cutting element (4) and the support structure (14), and wherein said spacer (15) being provided in abutting contact with the first cutting element (4) on the one side and with the support structure (14) on the other side.
3. Cutter system according to anyone of the preceding claims, wherein said cutting air gap (25a, 25b) size is dimensioned to be less than 0,04mm.
4. Cutter system according to anyone of the preceding claims, wherein (14), said first cutting element (4) being provided in a flat plate-like configuration having a skin top side, two lateral non hair cutting sides and two longitudinal sides each with a row of first cutting teeth (6), said second cutting element (5) being provided on each of its longitudinal sides which extend parallel to the movement direction with a row of second cutting teeth (7) and a flat main portion connecting both rows of second cutting teeth, said second cutting element (5) has a top side directed towards the first cutting element (4) and an underside directed towards the support structure (14), wherein at least some of the second cutting teeth (7) are uncovered at least at its tip portion at the underside of the second cutting element (5) forming a discharge area for cut hair stubbles, wherein said spacer (15) forms a sliding guide for guiding the sandwiched cutting element (5) reciprocating or rotate along said spacer (15) and having a guiding recess in which the spacer (15) is received, wherein said support element (17), said spacer (15) and said other cutting element (4) are rigidly connected to each other and form a rigid sandwiching frame having a gap (16) in which the sandwiched cutting element (5) is slidably received.
5. Cutter system according to anyone of the preceding claims, wherein the second cutting teeth (7) are provided with a teeth baseline at which the second cutting teeth (7) starts to project from the main portion of the second cutting element ( 5), the second cutting teeth have a second tooth length (tl) from the baseline to the free tip along its longitudinal extension, wherein the said support structure includes a support element (17) having an edge portion (23) which is in supporting contact to at least one of the second cutting teeth (7) or with a distance to the baseline of at least one of second cutting teeth (7) less than 2 times the second tooth length (tl) or with a distance to the baseline of at least one of second cutting teeth (7) less than the second tooth length (tl) or with a distance to the baseline of at least one of second cutting teeth (7) less than half of the second tooth length (tl).
6. Cutter system according to the preceding claim, wherein said support element (17) has a wave-shaped or toothed edge portion (23) which is in supporting contact to the second cutting teeth (7) of the sandwiched second cutting element (5).
7. Cutter system according to claim 5, wherein said support element (17) has a straight edge portion on both sides adjacent to each of the rows of the second cutting teeth.
8. Cutter system according to anyone the preceding claims, wherein said support element (17) includes a support plate forming a support surface which is substantially planar and/or has a shape substantially corresponding to the surface of the first cutter element (4) so that said gap (16) formed between the support surface of the support plate and said cutter element (4) has a substantially constant width.
9. Cutter system according to the preceding claim, wherein said support plate has an outer contour which corresponds to the outer contour of the sandwiched cutter element and/or is substantially rectangular.
10. Cutter system according to anyone of the preceding claims, wherein the sandwiched cutter element (5) includes at least one elongated or slit-like throughhole (19) through which said spacer (15) extends.
11. Cutter system according to the preceding claim, wherein said sandwiched cutter element (5) includes two or more parallel, elongated or slit-like throughholes (19) through which two or more spacers (15) extend.
12. Cutter system according to the preceding claim, wherein a further throughhole (74) is provided between said at least two or more parallel, elongated or slit-like throughholes, said further throughhole forming a discharge passage for cut hair stubbles,
13. Cutter system according to anyone of the preceding claims, wherein the support element (17) includes a throughhole (74) forming a discharge channel for hair stubbles.
14. Cutter system according to anyone of the preceding claims, wherein said sandwiched second cutting element (5) is non-detachably held between the first cutter element (4) and said support element (17) with at least one of the spacer (15) extending through a/said throughhole in the sandwiched cutter element (5) and wherein at least two fixations between the first cutting element (4) and at least one of the spacer are located decentral at the first cutting element with respect to a direction perpendicular to the movement direction of the second cutting element (5)
15. Cutter system according to the preceding claim, wherein said decentral fixations of the first cutting element (4) are located with a distance to the baseline of at least one of second cutting teeth (7) less than 2 times the second tooth length (tl) or with a distance to the baseline of at least one of second cutting teeth (7) less than the second tooth length (tl) or with a distance to the baseline of at least one of second cutting teeth (7) less than half of the second tooth length (tl).
