  • Patent number: 6199284
    Abstract: Shears for cutting metal sheet include first and second jaws pivotably interconnected by a jaw joint. The jaws have respective cutting edges located forwardly of the jaw joint, and which are arranged to cross one another at a crossing point which moves during a cutting operation. The cutting edges are configures to cross one another at a substantially constant angle during a cutting operation. The second jaw includes an extension extending rearwardly of the jaw joint. The first jaw has a rigidly attached first gripping handle. A second gripping handle is pivotably connected to the first handle by a handle joint located rearwardly of the jaw joint. The second handle engages a surface of the extension by a sliding contact, whereby a distance between the jaw joint and the sliding contact increases during a cutting operation.
