Abstract
The tool reduces or stops the flow of liquid or gas through a conduit and includes a crimping section, comprised of a first and second crimping member pivotally engaged with each other, and a handle section, comprised of a first and second handle member pivotally connected to each other. Each crimping member has a blunt section extending partially along an edge thereof. The first and second handle members are connected to the first and second crimping members. The conduit is crimped by applying a force to the handle members causing the handle members and the crimping members to pivot in a direction opposite each other so that the blunt sections of crimping members crimp a conduit placed therebetween thereby reducing or stopping the flow of the liquid or gas flowing through the conduit. The tool may also hold objects and be locked via separate locking mechanisms.
