one of the arms has a flat tip screwdriver, the other has a phillips head driver, the other is a wine bottle opener, and the final one is a holder for nails that keeps you from smashing a finger.
that nail holder is my favorite. you put the nail into the guide, and hold the tool. then you whack the coral tool on the top and the nail gets started without you missing and hitting your fingers. i hope this concept makes the leap into the real world.
