About those box cutters

Rico was thinking, given the reference in the Strangers On My Flight song, that no one, to the best of his recollection, has ever actually shown what the infamous 'box cutters' used by the 9.11 hijackers looked like.
One of these (technically, a carpet knife)?










or one of these (a sheetrock knife)?






Either way, Rico likes to think that, like Frank, he'd have taken on the little ragheads, even with a box cutter. The old detach-the-seat-belt-and-use-it-like-a-whip thing is probably the tack Rico would have taken...
