I guess I'll de-lurk...

I have carried a util-a-key for quite a few years. I've successfully carried it on a number of flights, including international flights. However, the last time I flew was in the summer of 2002 so YMMV.

I keep a very slimmed down keychain -- 5 real keys, util-a-key, fingernail clippers and small metal whistle -- and it wasn't noticed. If you are one of those people that has dozens of keys on your keyring(s), I think it would blend in even better. Throwing your keyring in the bottom of a purse or carry-on bag probably wouldn't hurt either.

I really like having a serrated edge any time there's a possibility I might need to cut through a seat belt. The util-a-key isn't much, but it's better than nothing. Also, it's cheap enough that if it's confisicated at the gate it's no great loss.

Another possible "stealth" knife is this:

which looks even more like a key.
