Defused grenades and “Satan’s pizza cutter” were among the 10 strangest things that Transportation Safety Administration agents found when scanning passengers’ carry-on luggage during airport security checks last year.

The items listed by TSA spokesman Bob Burns in a clever, funny video include defused hand grenades, “Satan’s pizza cutter,” a rifle-shaped umbrella, and a lightning bolt-shaped martial arts throwing star, which Burns refers to as the “international symbol for ‘I’m single, ladies.'” Travelers inexplicably thought they could take the items on a plane.
