Once you’ve gotten used to keeping a multi-tool on you, it can be hard to go without. But the TSA doesn’t care about that, and good luck getting your Leatherman on a plane.

The Gerber Shard isn’t as fancy as a lot of mini tool gizmos, but it’s airline approved and it fits on your keychain — and it’s $5. It features three drivers, a wire stripper, a pry bar, and a bottle opener, so maybe it’s just enough to keep you from having handy gadget withdrawals in “no weapons” situations. (It’s also a nice little gift for people that don’t really need or want anything else.)
