1. A pipe wrench, comprising:

  • a main body for providing a handle;

    a fixed jaw coupled to the main body, the fixed jaw being formed by at least two arcing jaw faces that are congruent and extend away from the main body;

    an angled jaw pivotably coupled to the main body for interacting with the fixed jaw for clamping, the angled jaw having at least two substantially straight jaw faces which face the at least two arcing jaw faces at an angle to each other for providing a three-point grip in conjunction with the fixed jaw during clamping; and

    a pivot disposed on the main body adjacent to the fixed jaw for pivotably coupling the angled jaw to the main body,wherein the angle between said at least two substantially straight jaw faces of the angled jaw is obtuse and a radius of curvature of a first arc subtending the arcing jaw face proximal to the pivot is smaller than a radius of curvature of a second arc subtending the arcing jaw face distal to the pivot.
