The hammer head has grooves on each side which act as adjustment stops for a sliding wrench jaw. A spring which can be inserted into the grooves acts to hold the adjustment. The jaw faces on opposite sides are spaced differently so that each adjustment stop provides two sizes of wrench opening.

The specifications say the handle could be of any material although the drawing shows a metal shank with a screwdriver tip.
