Abstract: The present invention may be used for rotating a polygonal object. A first wrench member may have a handle with two ends with a fixed jaw attached at a first end and with a cavity formed in the fixed jaw and first end. A second wrench member may be a movable jaw with a curved jaw attached to a ratcheting element. The ratcheting element may be slidably positioned in the cavity to position the curved jaw opposite the fixed jaw. The second wrench member may be constrained by the cavity and a cavity insert member to slide in said cavity about the center of an arc. The second wrench member may be spring biased by an elastic compression element to move toward the fixed jaw. A gripping surface of the curved jaw may be structured relative to the center of the arc to cause the curved jaw to be urged toward the fixed jaw when rotating the fixed jaw against an intervening polygonal object, and to cause the movable jaw to ratchet open when the handle is rotated in the opposite direction.
