If you aren’t familiar with a leatherman, it is an extremely useful tool to carry in your pocket:
Sort of a Swiss army knife for travelers. Folding out into needlenose pliers for removing cotter pins when removing wheels for a flat repair, screw drivers for quickly fixing things without having to get out your tools that are packed away. Knife, bottle opener, file, scissors. It comes in handy for a multitude of things and is great to have in your pocket where you can quickly get to it. You'll use it on a trip more than any other tool.
Alas, I lost my leatherman. And here is the problem. When I fly back to South America I don’t have checked luggage. I wear my riding pants and jacket, and have a small carry-on with my helmet and laptop. That’s it. No way I can get a leatherman through airport security.
The owner of leatherman had a similar problem. They wouldn't let him through security at Disneyland. No knives. Bummer. So he came up with a useful leatherman tool disguised as a wristband or watchband that he takes on trips:
It is approved for airport security but contains screwdrivers, allen wrenches and box wrenches within the band itself. Just take it off, fold it to the proper size tool and use the stiff band as a handle. What a great idea! Plus it will be harder to lose if it is actually on your wrist instead of in a pocket where it can fall out and become lost like mine did. It doesn't have the needle nose pliers and knife, but hey, it has box wrenches and screwdrivers which is what you need most of the time. And when you're too cheap to pay for checked luggage this is just the ticket. I can see that mat black one on my wrist. Not sure if it would work with my cheap Casio watch. But if not, I'll just wear it as a wristband on the other hand I guess.
