A cutting tool includes a first lever having a first end and a second end, the first end being connected to a second elongated element in an articulated manner at a third pivot point and the second end being arranged to engage with a tongue in a metal plate to transmit force from the second elongated element to a first blade in the metal plate so as to perform a cutting movement with a cutting jaw when the first and the second elongated elements are shifted towards one another. The cutting tool also comprises an engagement device provided in the tongue and arranged to receive the second end of the lever optionally at two or more engagement points with respect to the first pivot point so as to perform stepwise cutting movements. The engagement points are placed in the tongue successively away from the third pivot point.
