Abstract: A multiple use fitters tool assembly provides multiple tools used by pipe fitters in a single convertible unit. The assembly includes a pair of elongated arms pivotally coupled together defining an upper handle, a lower handle, an upper jaw, and a lower jaw defining a pipe wrench. A tool slot extends into the pipe wrench. Each of a plurality of extendable tools is pivotally coupled to the pipe wrench in the tool slot and pivotable between an extended use position and a storage position. Selectable pairs of first and second gripping surfaces are couplable to the upper jaw and the lower jaw. A storage void extends into the pipe wrench. Each of the first gripping surfaces and the second gripping surfaces is selectively couplable to the pipe wrench in the storage void when not coupled to the upper jaw and the lower jaw.
