Re: airport security
After forgetting it was in my laptop bag whilst travelling half way around the planet through multiple airport hubs, I got stopped at Bayun airport (Guangzhou, China), and a teeny tiny multitool, complete with a blunt 1" blade was confiscated.
Wearily I clambered onto the China Southern plane to Amsterdam, and was given a large, razor sharp steak knife to eat my noodles with.
