Interesting 10min podcast on the history of the swiss army knife <a href=”http://feedproxy.google.com/~r/TheHistoryNetwork/~5/fdWwUtioc8k/704_Swiss_Army_Knife.mp3″>here</a>. Apparently worldwide sales dived by 40% after 9/11 because a lot of them were bought duty free, and even sold in-flight. Oh how things change. I personally can vouch for the casualty of one small swiss army knife at the airport in Guangzhou. I forgot to take it off my key ring and by the time I got to the queue for security it was too late to suitcase it.
