The utili-key looks like a regular key on your keyring, which is why I've never had it confiscated at airport security. Frankly if you can hijack a plane with one of these things, you can hijack a plane without one of these things.
The USB is a "Lacie imakey". Lacie has since been assimilated into one of the big hard drive companies (Seagate I think). These USB keys are a victim of their success. You just buy the one, and never need another. This one is over ten years old.
