Abstract
In a pair of scissors, particularly hairdresser's scissors, with a pivot joint consisting of a pivot screw (1) and a screw nut (18), where the pivot screw (1) is connected to one scissor blade (21) in an essentially non-rotating fashion, play between the pivot screw (1) and the one scissor blade (21) is to be prevented by providing the screw nut (18) with an annular groove (10) in its inner wall, in which an annular body (11) made of flexible material is located, the inside diameter of which is smaller that the thread diameter of the pivot screw (1), and by the screw nut (18) additionally having a flexible moulding (22) on its inner face, which contacts the screw nut (18) and the wall of the drilled hole (20) in the one scissor blade (21) when under pressure.
