    Abstract: A pipe wrench with an extendable handle is provided. The extendible handle may include a web and a flange to reduce bending stress. The pipe wrench may include a locking button that slides within a channel of the web to lock the extension handle at predetermined extended or retracted lengths. The locking button selectively enables the extension or retraction of the extension handle relative to the first handle of the pipe wrench. The locking button is biased by a spring and coupled to the extension handle with an e-clip. The body, the first handle, and/or the extension handle can include composite materials. In some embodiments, carbon fiber reinforced plastics, fiberglass reinforced plastics, and/or other reinforced polymers are used to form one or more features of the pipe wrench.

    Abstract: A tool for bending an elongated workpiece includes a shaft having a first shaft portion and a second shaft portion, and a coupling assembly coupling the first shaft portion and the second shaft portion. The coupling assembly has a locked configuration in which the coupling assembly inhibits movement of the first shaft portion relative to the second shaft portion and an unlocked configuration in which the coupling assembly permits movement of the first shaft portion relative to the second shaft portion. The tool also includes a shoe coupled to the second shaft portion. The shoe has a curved bottom portion and a hook configured to hold the workpiece against the curved bottom portion. The curved bottom portion is engageable with the workpiece to bend the workpiece.
