Description:
The knife includes adjustable wrench with a screwdriver blade on the tip of the movable jaw shank. The pintle pin for the knife blades has lugs on the sides, and is held in place by a spring. The pivot holes in the blades include notches corresponding to the lugs. The lugs hold the blades in either open or closed position, with the pintle having to be depressed to open or close a blade. This construction would allow one-handed use with the blade swung by gravity. The hook blade on the other end of the knife frame is held in position by a spring.
