What is the name of a pipe wrench that has jaws operating at an angle to the handle axis?

The name of a pipe wrench that has jaws operating at an angle to the handle axis is the offset pipe wrench. This design allows for greater access in tight spaces where a straight pipe wrench may not be able to fit comfortably. The offset jaws enable the user to exert torque on pipes that are in awkward positions or near other obstacles, making it an essential tool in plumbing and pipefitting applications.

In contrast, a straight pipe wrench features jaws that align directly with the handle, limiting its use in certain situations. The end pipe wrench, while it might suggest a similar angle, is not specifically designed for offset access. The RapidGrip pipe wrench is a different style that focuses on speed and ease of adjustment for gripping pipes, but it does not have the distinct angled jaw feature of the offset pipe wrench. Thus, the offset pipe wrench is uniquely suited for tasks that require maneuverability and flexibility not provided by other types of pipe wrenches.
