The handle in question is for a combined wrench and screw driver. The metal blank is stamped; the blank undergoes subsequent folding and drop forging processes to form the finished piece -- a hollow handle with integral fixed jaw, and slots for adjusting nuts for the screwdriver bit and movable jaw of the wrench.
