"Pean’s Hemostatic Forceps - the earliest and best known form of this class, they are of light construction with a distance from fulcrum to jaw of at least one third of its total length, making it best suited where minimal force is required.  Occasionally, the jaws are equipped with additional grooves so that a needle may be held. The catch has two or more teeth so that varying degrees of pressure may be obtained."  1899 Truax fig. 648
