The TSA's rules are constantly changing, and it can be difficult to know what you are allowed to have on a plane. Because of this, we've broken down the best survival and self-defense tools TSA will allow in this handy guide.
All of the tools shown below are 100% TSA approved, meaning they will allow you to carry them in your carry-on bag on a flight without hassle. Unless things change again. (I had half plastic, half metal baby fingernail clippers seized from me once.)
Just in case the TSA gets overzealous, you can prevent your multitool from being stolen from you. One travel hack that works for some is to open up all the tools and place it in the change tray. If that doesn't do the trick, another quick tip is to pack an envelope with pre-paid postage. That way, if you run into any problems, you can avoid confiscation by mailing it home or to a friend instead.
