You could also pinch the BG with the pliers or in a worst case situation use them as a "nut crusher". Also if the BG is wearing glasses you could use the little screw driver to unscrew the arm on his glasses, making them fall off and blind him. OR you could just toss the whole ten ounce tool at him as a distraction and run like hell, that just may be your best bet. But you could use the saw blade to cut down a sapling to hit him with, and if the sapling had a beehive they would sting the BG just like in cartoons. That would be very tactical.
I carry a multitool because it is not a weapon but strictly a tool, never get a hassle about it.
Take care and stay safe,
