The invention relates to a pliers, in particular a center cutter, having two pliers limbs () arranged to cross in a joint which forms a pivot axis (), the two pliers limbs () forming, on one side of the joint, interacting working regions () that have free ends (), and the pliers limbs having gripping limbs () 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 () is formed in the shape of a U on the joint side and that the pivot axis () passes through the U-limb ().

Pliers

A pipe wrench or water pump wrench includes a clamp having a first shaft-like grip part and a handle having a second shaft-like grip part. A first jaw having a first gripping surface is disposed at one end of the clamp and a second jaw having a second gripping surface is disposed at one end of the handle. The second gripping surface is formed so as to be complementary to the first gripping surface. The jaws extend in a jaw gripping direction. The gripping surfaces form a first gripping recess. An adjusting mechanism having a toothed slot is disposed in the clamp. The toothed slot is curved in the jaw gripping direction. A pivot pin connects the clamp and the handle in a pivotable manner with respect to one another. The pivot pin is displaceable via the adjusting mechanism.
