I’d get one just to challenge, piss off, and win against the TSA “agents”...
Don't waste your money. I had a very tiny allen wrench in the coin pocket of my jeans. It had been there for months after adjusting the sights on my rifle. A small one that only comes in a full set. The TSA metal detector spotted it. I fished it out of my pocket. The bonehead TSA inspector said he had to confiscate it. It's a tool. I looked him in the eye and said, "you're a tool". I had to spend $10 to buy another full set to replace the confiscated item. Again, the TSA isn't playing with a full deck. They will confiscate your nice new bladeless tool. Expect to see it on E-Bay later.
A while back I got into an argument with tsa dork who stupidly tried to explain that my razor knife (minus blade) wasn’t allowed.
I pulled up their website which allows for tools up to 7” long and doesn’t differentiate.
He told me I had to use their app. I told him to take a hike, I’m not downloading their stupid app when their official website doesn’t define it.
Sadly, The moron beat me since I needed to get to my flight.
