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.
