A cutter member for a rotary shaver includes a number of cutters arranged in at least two rings around a central axis, and a number of upwardly bent arms connecting the cutters to the central base. The rings are formed by bending some of the arms more outward and/or inward than others. Further, the cutter member may be made by consecutively cutting a blank of sheet material so as to have a number of arms with cutters and by bending some of the arms more outward and/or inward than others, so as to arrange the cutters in the at least two rings.

1. A cutter member for a rotary shaver, the cutter member comprising: a plurality of cutters for cutting hair arranged in at least two rings around a central axis of the cutter member, anda number of upwardly bent arms connecting the plurality of cutters to a central base, wherein a first set of the arms connected to the central base is bent more outward of the central axis than a second set of the arms connected to the central base,the plurality of cutters including a first set of cutters connected to the first set of arms, the first set of cutters being arranged along an outer ring of the at least two rings, andthe plurality of cutters further including a second set of cutters connected to the second set of arms, the second set of cutters being arranged along an inner ring of the at least two rings, the inner ring being closer to the central axis than the outer ring,wherein the outer ring of the at least two rings comprises more cutters than the inner ring of the at least two rings, andwherein the at least two rings comprises two substantially concentric rings of cutters including the outer ring and the inner ring, wherein the outer ring is formed by bending some of the arms upward and outward and the inner ring is formed by bending remaining of the arms upward and inward. 2. The cutter member according to claim 1, wherein each arm consists of only one cutter. 3. The cutter member according to claim 1, wherein the arms are bent outward or inward around a bending axis extending substantially parallel to, or including a small angle with a normal of the central base. 4. The cutter member according to claim 1, wherein the arms are bent outward or inward around a bending axis extending substantially parallel to a tangent of an upright portion of the arms or including a small angle with the tangent of the upright portion of the arms. 5. The cutter member according to claim 1, wherein at least a number of the arms, in unbent condition, is of substantially L-shaped design, including a first leg extending substantially radial from the central base and a second leg extending substantially tangential to the central base, wherein a free end of said second leg is provided with a cutting edge. 6. The cutter member according to claim 1, wherein at least a number of the cutter arms in unbent condition, is of substantially Z-shaped design, including a first section extending substantially radial from the central base, a second section extending approximately tangential to the central base, and a third section extending substantially radial from the central base, staggered with respect to the first section. 7. The cutter member of claim 1, wherein the first set of the arms are bent inward of a first bending axis, and the second set of the arms are bent outward of a second bending axis, the first bending axis extending substantially parallel to a normal of the central base, or including a first acute angle with the normal of the central base, and the second bending axis extending at a second acute angle with a tangent to the central base. 8. A rotary shaver comprising: a first cutting member;a second cutting member; anda hair pulling member;wherein the first cutting member comprises:a plurality of cutters for cutting hair arranged in at least two rings around a central axis of the first cutting member, anda number of upwardly bent arms connecting the cutters to a central base, wherein a first set of the arms connected to a central base is bent more outward of the central axis than a second set of the arms connected to the central base,the plurality of cutters including a first set of cutters connected to the first set of arms, the first set of cutters being arranged along an outer ring of the at least two rings, andthe plurality of cutters further including a second set of cutters connected to the second set of arms, the second set of cutters being arranged along an inner ring of the at least two rings, the inner ring being closer to the central axis than the outer ring,wherein the outer ring of the at least two rings comprises more cutters than the inner ring of the at least two rings, andwherein the at least two rings comprises two substantially concentric rings of cutters including the outer ring and the inner ring, wherein the outer ring is formed by bending some of the arms upward and outward and the inner ring is formed by bending remaining of the arms upward and inward. 9. The rotary shaver of claim 8, wherein the first set of the arms are bent inward of a first bending axis, and the second set of the arms are bent outward of a second bending axis, the first bending axis extending substantially parallel to a normal of the central base, or including a first acute angle with the normal of the central base, and the second bending axis extending at a second acute angle with a tangent to the central base. 10. A method for making a cutter member for a rotary shaver, comprising the acts of: cutting a blank of sheet material so as to have a plurality of cutters for cutting hair integrally connected to a central base via a number of arms; andarranging the cutters in at least two rings, above the central base, by bending a first set of the arms connected to the central base more outward of a central axis of the central base than a second set of the arms connected to the central base, wherein the arms are bent in such way that a number of cutters in an outer ring of the at least two rings is larger than a number of cutters in an inner ring of the at least two rings,wherein the plurality of cutters includes a first set of cutters connected to the first set of arms, the first set of cutters being arranged along the outer ring of the at least two rings, andthe plurality of cutters further includes a second set of cutters connected to the second set of arms, the second set of cutters being arranged along the inner ring of the at least two rings, the inner ring being closer to the central axis than the outer ring, andwherein the at least two rings comprises two substantially concentric rings of cutters including the outer ring and the inner ring, wherein the outer ring is formed by bending some of the arms upward and outward and the inner ring is formed by bending remaining of the arms upward and inward. 11. The method of claim 10, wherein the first set of the arms are bent inward of a first bending axis, and the second set of the arms are bent outward of a second bending axis, the first bending axis extending substantially parallel to a normal of the central base, or including a first acute angle with the normal of the central base, and the second bending axis extending at a second acute angle with a tangent to the central base.
