I’m confused. I carry a small, mini sized Swiss Army knife with me almost always, in some pocket or other. By habit, when I reach the check in desk at an airport, it goes in to my hold luggage, as I’d always assumed that you couldn’t take them through the security scanners.
However, twice this year I’ve forgotten and left it in my pocket, only noticing much later on. No alarms went off, no lights flashed. Both times at pretty major international hubs. So, what’s the score? Can you take a small knife on a plane or not?
