Recently I saw a thing called a 'sgian brew' which is a traditional sgian dhu handel on a bottle opener instead of a blade. I wonder if security would confiscate one of these ?
Talking about airport security, during a recent trip to Minneapolis I gave my Father In Law a couple of bottles of beer and when we came to leave the hotel he realised he hadn't drank one of them. He was hurridly going to consume it when his wife said "Take it to drink at the airport". Of course they confiscated it at the security check in and I've never seen him looking so upset!
