ok so heres what you do
take a pencil sharpener, preferably those without the things for the pencil bits
if you dont have a pair of the snippy snips (i cant f**king spell it oh my god) or a screwdriver, the lego part #3841 (grey pickaxe) works to unscrew the screw
sometimes i get sharpeners that are f**king bastards so i just break the plastic
