A pivoting jaw pipe wrench comprises a fixed jaw including a plurality of discrete teeth, each for a different one of a plurality of pipes having different diameters. A pivotal jaw member has first and second jaw faces at an obtuse angle to one another and displaceable toward and away from the fixed jaw, whereby a pipe of given diameter to be gripped by the wrench is cradled between the first and second jaw surfaces and engaged by the one of the discrete teeth provided on the arcuate jaw for the pipe of given diameter.
