<p>The invention relates to a cutting tool which comprises a first lever (22) having a first end (26) and a second end (28), the first end (26) being connected to a second elongated element (16) in an articulated manner at a third pivot point (24) and the second end (28) being arranged to engage with a tongue (8) in a metal plate (2) to transmit force from the second elongated element (16) to a first blade (6) in the metal plate (2) so as to perform a cutting movement with a cutting jaw when the first and the second elongated elements (10, 16) are shifted towards one another. The cutting tool also comprises engagement means (30) provided in the tongue (8) and arranged to receive the second end (28) of the lever (22) optionally at two or more engagement points (32,34,36) with respect to the first pivot point (4) so as to perform stepwise cutting movements. The engagement points (32,34,36) are placed in the tongue (8) successively away from the third pivot point (24).</p> |
