The hammer portion can be fixedly mounted on the closed jaws of the tongs portion to form an independent hammer. A saw blade can be removed from one of the hand grips of the tongs portion and locked into one end of the hammer portion to form an independent saw. A screwdriver bit can be removed from another end of the hammer portion and locked into the same end of the hammer portion where the saw blade can be locked, to form an independent screwdriver. The tongs when disassembled from the hammer portion can be used as a conventional pair of pincers.
