Today three of my co-workers told stories of knife security/non-security in airports.

One said she & her husband were almost not allowed on a flight because of her husband's bowie knife. He always carries it, but it was the first time they'd ever flown so they had no idea it might be a problem. In the end they were allowed on and HE KEPT HIS KNIFE on the flight.

One said her father always carries a pocket knife & put it into the change container when going through security. Flying Toronto-London not a word was said. Back from London, it was taken away & returned at the end of the flight.

One's 15 year old son had a serious camping knife in his backpack, forgotten from camp. Going US to London (not sure of city), nothing was said. London->back whole family immediatly surrounded & high level security summoned. Forms were filled out for tracking purposes (don't make this a habit) & travel continued. I'm not sure who had the knife during the flight itself.

There are a lot of people who carry knives as a habit so I suspect the airport security people got tired of making a big deal. I see no problem with making it a little deal for everyone. Check your knife, please & it will be returned at your destination.
