Metal shears comprising two jaws (11,13) with edges crossing at a jaw crossing point (20) where at least one edge is convexly curved, and two handles (12,14) where a first jaw is rigidly attached to a first handle and the jaws are connected at a jaw joint (15), and where the second jaw has an extension (18) inserted in an opening in the second handle (14) and the force is transmitted from the second handle to the extension at a contact point (17) sliding against the extension, and the extension is curved such that the ratio between the distances from the contact point (17) and the jaw crossing point (20) to the jaw joint is generally constant when the handles are pressed together for cutting. <IMAGE>
