    8. The combination according to claim 7, wherein the front portion of the second blade of the first pair of scissors and the front portion of the second blade of the second pair of scissors are formed differently, whereas the rear portion of the second blade of the first pair of scissors and the rear portion of the second blade of the second pair of scissors are formed identically.

    9. The combination according to claim 1, wherein the front portion extends from the fastening element up to the front end and/or the rear portion extends from the fastening element up to the rear end.

    10. The combination according to claim 1, wherein the rear portion comprises a tang designed for fastening a handle thereto, wherein the tang of the first blade of the first pair of scissors is formed identically to the tang of the first blade of the second pair of scissors and/or the tang of the second blade of the first pair of scissors is formed identically to the tang of the second blade of the second pair of scissors.

    11. The combination according to claim 1, wherein the rear portion comprises a joint, wherein the joint of the first blade and the joint of the second blade of each pair of scissors rub on each other when the two blades are rotated against each other, wherein the joint of the first blade of the first pair of scissors is designed identically to the joint of the first blade of the second pair of scissors and/or the joint of the second blade of the first pair of scissors is designed identically to the joint of the second blade of the second pair of scissors.

    Description

    BRIEF DESCRIPTION OF THE DRAWINGS

    [0015] Hereinafter, an embodiment of the disclosure will be explained in more detail with reference to the Figures. In the Figures:

    [0016] FIG. 1 shows a first pair of scissors,

    [0017] FIG. 2 shows the two blades of the first pair of scissors,

    [0018] FIG. 3 shows a second pair of scissors,

    [0019] FIG. 4 shows the two blades of the second pair of scissors,

    [0020] FIG. 5 shows a third pair of scissors, and

    [0021] FIG. 6 shows the two blades of the third pair of scissors.

    DETAILED DESCRIPTION

    [0022] Each of the three pairs of scissors 12, 14, 16 of the embodiment shown in the Figures comprises two blades 18, 20 which are connected to each other by a fastening element in the form of, for example, a screw, which is not illustrated in the Figures. Here, the fastening element is fastened, e.g. screwed, through the two fastening holes 22 illustrated in the Figures, the two blades 18, 20 being rotatable towards each other in the fastened and connected state.

    [0023] Each of the two blades 18, 20 of each par of scissors has a front end 24 and a rear end 26 opposite the front end 24. A front portion 28 of each blade extends from the front end 24 up to the fastening opening 22. A rear portion 30 of each blade 18, 20 extends from the fastening opening 22 to the rear end 26. Each rear portion 30 has a joint 32 and a tang 34. The joints 32 of the two blades 18, 20 of each pair of scissors 12, 14, 16 are designed and arranged such that they rub on each other when the two blades 18, 20 are rotated towards each other.

    [0024] The tang 34 is the section of each blade 18, 20 that extends between the joint 32 and the rear end 26 and has a comparatively small width and a shape that allows the attachment of a handle 36, e.g. by injection molding a plastic handle thereto. For this purpose, the tang 34 of each blade 18, 20 is provided with an indentation 40 that prevents the attached handle 36 from slipping off. Other designs of the shape of the tang 34 of the blades 18, 20, which allow for a suitable attachment of a handle 36 that prevents slipping of the handle 36, are also conceivable.

    [0025] It can be seen in the Figures that the front sections 28 of the blades 18, 20 of each pair of scissors 12, 14, 16 are designed differently. The front sections 28 of the first pair of scissors 12 are designed to taper towards the front ends 24 and are designed with almost straight edges. The front sections 28 of the second pair of scissors 14 are formed rounded in the region of the front ends 24. The front sections 28 of the third pair of scissors 16 are designed to taper to the front ends 24 and are designed with curved edges.

    [0026] In contrast, the rear portions 30 of the blades 18, 20 of each of the three pairs of scissors 12, 14, 16 are designed identically. As a consequence, also the joints 32 and the tangs 34 are identical. Each of the three pairs of scissors 12, 14, 16 thus shows identical friction and identical friction behavior between the joints. In addition, the same or similarly designed handles 36 can be attached, e.g. by an injection molding process, to the rear portions 30 of the three pairs of scissors 12, 14, 16, using the same manufacturing methods and the same manufacturing tools.

    [0027] In the present context, “identically designed” or “identically formed” means that the size, shape, outer dimensions, and the course of the contour of the outer edge correspond to each other, i.e. are the same. In contrast, in the present context, “differently designed” or “differently formed” means that the size, shape, outer dimensions, and the course of the contour of the outer edge are different, i.e. differ from each other.
