摘要:
The invention relates to a pliers, in particular a center cutter, having two pliers limbs (6, 7) arranged to cross in a joint which forms a pivot axis (8), the two pliers limbs (6, 7) forming, on one side of the joint, interacting working regions (2, 3) that have free ends (15, 16), and the pliers limbs having gripping limbs (10, 11) on the other side of the joint. In order to improve a pliers of the kind specified at the beginning in such a way that an advantageous design structure is achieved for the greatest possible force transmission ratio, it is proposed that one of the pliers limbs (6) is formed in the shape of a U on the joint side and that the pivot axis (8) passes through the U-limb (12).
