This design can be used as a Carabiner and a Plier. The two handles can connect and the blades attached to the handles to form a plier. The plier can cut some loose cables in the spacecraft. The blades can also be detached and the two handles can join together to form a carabiner. This design helps the astronaut to tighten himself with the ropes attached to the carabiner and also perform tasks with cable wires with the help of the plier easily.
