In these tools, the pivotable joint, which is formed concurrently with the handles, is an integral part of one of the handles.

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.

Abstract: In tools for clipping material of different hardness and dimensions, there are required blade-portions (1, 2) having different characterics. A pliers jaw, the blade-portion of which is formed with different edge angles (a.alpha..sub.1, .alpha..sub.2), different edge radii and different widths (b, B) on its outer chamfer surface (5) results in a tool which is usable for different materials. By configuring different cutting areas (6, 7) by distinctly machining the jaw, the right cutting area can easily be localized for the material in question that is to be cut.

Abstract: A pair of secateurs is provided comprising two handle (2,4) and blade (10,12) modules pivotally connected together such that when the two handles are moved towards one another, the two blades move towards one another to perform a cutting operation. The secateurs are such that each blade (10,12) can be released from each associated handle (2,4) without the use of tools, for replacement by a new or different blade. The invention makes it possible to replace worn or damaged blades without the need for any tools such as a spanner or screwdriver. It further allows the same pair of handles to be used with blades of differing configurations, making the secateurs much more versatile than known secateurs.
