Abstract: A pipe wrench that includes a head including an aperture and a first jaw including a plurality of teeth that define a contact region. The wrench further includes a second jaw that extends through the aperture of the head and includes a threaded portion and a plurality of teeth that define a contact region. A thumb wheel moves the contact region of the second jaw toward and away from the contact region of the first jaw. An auxiliary drive is spaced from the contact regions of the first and second jaws, and the auxiliary drive includes a first auxiliary drive portion located on the first jaw and a second auxiliary drive portion located on the second jaw such that rotation of the thumb wheel moves the second auxiliary drive portion toward and away from the first auxiliary drive portion.
