Buddy of mine had a knife in his carry on when we where leaving Turkey once... he almost missed the flight because of it.
sometimes we just forget.
Same here.i had a leatherman multitool in my carryon (it has the standard knife). cost me 80 bucks. they confiscated at JFK. said, you can either go drop and come back or we confiscate it. my flight was about to leave, i said eff it, take it. I replaced when i returned.
my Credit card style multi tool in my wallet, gets dinged everytime at security check (Westchester Permit office / PA permit office etc). i completely forget its there.

I bought a stainless one early on. Then I discovered that they have a big design flaw in the frame that leaves them prone to cracking, at which point they are worthless. Mine was one of the so called newer ones that they had redesigned and made the part that typically broke a little thicker.A Beretta Tomcat no less. One of the models I passed on.
