Vampire Tools' family of pliers incorporates VamPLIERS technology which utilizes a patented design incorporating horizontal and vertical serrations into a concave shaped interior jaw surface to maximize the surface contact with the target screw or nut to be extracted. The jaw is also hardened so it can bite into the target to make it easy to extract. The jaw design also incorporates concavity at the tip to be able to extract low-profile screws. The most popular pliers incorporating VamPLIERS technology are a set of 6.5-inch pliers which can remove stripped, rusted, corroded, one-sided screws, and rounded nuts and bolts suitable for repair and maintenance of aircraft, automotive, motorcycle, and marine applications.
