I wouldn't dream of taking razor blades in my hand luggage. I almost permanently travel with a Futur in my wet pack, I usually carry it empty and try to get some blades locally. As a back up I have a Bic.
Security in airports have a hard enough job these days, queues get longer, and people get more impatient. It's difficult enough for the airport security staff without people that know the rules deliberately ignoring them.
[SIZE="1"]Ah... You can't beat the cold steel and the badger. All this electrical rubbish, little wheels spinning around all over the place for callow youths and peach fluff, Not for a man's beard. Razor blades for men! I think we'll have this on number 9. If you're going to have a shave have a close one!
