tools: swiss army knife-drive

This keychain disk integrated with a Swiss Army knife is very cool, even updating the features for geeks, eschewing the toothpick in favor of an LED light, and a ballpoint pen in lieu of a corkscrew. However, in the post-9/11 world, it is harder to get one’s knife after a flight than it is to wait for check-in baggage. I note that the drive is detachable, but I'd rather keep it all in one piece, and keep it all on my person, at all times. Isn’t that the point?
