The Vampire Vampliers have a patented design of vertical and horizontal serrations inside the jaws, with curved teeth at the nose. This feature allows the tool to “bite” into screw heads of various shapes without slipping or damaging the surface of the mounted screw. Made of carbon-treated steel, they are much easier to use than screw extractors or locking pliers, according to the manufacturer, because of the way the tool grips around truss, round or pan head screws. Additional features include a spring-loaded return, wire cutters and Ergonomic Elastomer handles. Made in Japan.
