ABSTRACT:
Scissors (1) having a first lever (2) and a second lever (2′) provided with respective coaxial holes (25, 25′) in their central portions (20, 20′) and a rivet (4) disposed in the holes (25, 25′) of the levers (2, 2′). The scissors further include a bush (3) interposed between the rivet (4) and the surface of the hole (25) of the first lever (2) so that the first lever (2) can rotate with respect to the bush (3) which is maintained integral with the rivet (4), and a washer (5) interposed between the rivet (4) and the surface of the hole (25′) of the second lever (2′), so that the outward deformation of a portion (42) of the rivet (4) compresses the washer (5) on the central part (20′) of the second lever, making the second lever (2′) integral with the rivet (4).
