Abstract
A pipe wrench is disclosed, the pipe wrench having a uniquely handy control lever and one-way ratchet for very rapid adjustment of wrench position. The wrench also has a pivoting upper jaw that further aids a user in adjusting and tightening the wrench while using only one hand. The wrench may also be used as a hand tool, for instance for clamping an object or workpiece for performing work on the object.
