Abstract
An improved vise for gripping elongated objects such as pipe is provided. The vise utilizes the rotational forces acting upon the object to be gripped to tighten the vise's grip on the object. The vise is constructed so that any force tending to rotate the object is transmitted to the vise and is translated into a gripping force to be utilized by the vise jaws of the vise. The vise is bi-directional and automatic in its operation.
