Found this tool. What's it called? Who makes it?

I call it my “american express tool”
Never leave home without it.
Think im on my 4 th one.
Lost 2, broke one.
Still a handy thing to have on my belt. Especially as a mechanic.
One i had, came with a file.
Had to get through a gate someone padlocked,otherwise a 2 hour trip back and 2 hours out again. So i filed it. 5 minutes.
Boss was impressed.
