Why would any self-respecting terrorist want to try boarding a plane with a knife or a gun???
Lets face it, you can do more damage to a person, sticking them with a well sharpened pencil, or a fountain pen, than you can with a 'craft knife'. Anyone who has any training in hand-to-hand combat, knows that a punch is better than a slap. And as the Romans proved, 'the point is more deadly than the edge'. So if you want to stop terrorists, be on the lookout for the bod with lots of pencils or pens in his luggage.
