Just a neat little tool that is usually compliant with most security restrictions. Obviously your mileage may vary. It's not going to rebuild an engine and it's not a toolbox, it's basically a novelty, but I have genuinely used it in situations where I needed a wrench (a bike seatpost binder bolt) and a few other things, and it works for those simple task.
It's always handy to have a tool to deal with openening boxes etc at a job site and I have flown with this " decal setter and scraper" about 5 times and had it examined by TSA once and it passed ok. It is well made and, with a Velcro wrap, becomes a very useful key fob.
Solid design like all the Leatherman tools. has both metric and imperial wrenches. Pocket friendly, fits into my Molle Leatherman sheath along with my Leatherman Surge.
