From abstract of the Kant-Twist clamps patent:

Clamp capable of mechanical clamping and optionally useful for providing especially high electrical conductivity having a pair of juxtaposed clamping jaws for gripping an object. One important use of the clamp is to grip an article through which high current is required to flow as, for example, in electric welding. At least one of the jaw blocks is of deep case-hardened cold rolled steel, and when used for high electrical conductivity, is copper coated. The face of this block is provided with concentric teeth which bite into the article. The outer faces of the teeth are perpendicular to the surface of the article being gripped.
