Abstract
A vise grip locking tool which contains jaws that are capable of opening with a flick of the user's wrist. The tool comprises a first handle member, a second handle member, a lower jaw, and an upper jaw. The first handle member is pivotally attached to the lower jaw. The first end of the lower jaw is made up of four mutually interconnected sides having a guided slot extending through it. The upper jaw has an elongated shank that may slide along the guided slot of the lower jaw. A stop is present on the bottom of the shank preventing the upper jaw from escaping the guided slot. The second handle member is pivotally mounted to the lower jaw and includes a releasable lock which is made up of a spring-operated detent which engages teeth on the elongated shank.
