It's the RP Tools Hex Punch and Die set! Just look at the hammer.... LOOK AT IT!!! It's so cute!! And it'll let you punch bolt heads out of ABS sheet no problem. And some people even use them on softer metal (not gonna do that.
Works great, and if you're bored you can take some scrap styrene or ABS sheet and spent an afternoon knocking out nuts.
TTFN,
