Had it for ages - almost lost it to TSA a few years back. Left it in my laptop bag - agent found it and told me to hurry back out while he called the baggage guys and had them pull my checked bag for me so I could toss it in then come back through.
So there are actually a few good TSA folk.
I carry a small Swiss Army knife also. I forgot about it and found it in my pocket in the TSA line. I tossed it in the small bowl with my pocket change and keys and sent it through the metal detector and picked it up on the other side. TSA must have missed it.
I carry a pocket knife and a 9mm everywhere. Cheap pocket knives. Lost one at a OKC Thunder game recently. Forgot it was in my pocket.
Something similar happened to me several years ago. I always carry a Swiss Army knife (not unlike yours, but mine has a corkscrew and no tweezers), a Gerber folder, and an original Leatherman, all of which I’ve carried for at least 20 years. I was in the Charlotte NC airport, and had put the knives in my checked-in bag, but forgot that the Leatherman was on my belt. The TSA guy didn’t confiscate it, but let me go find a box and check it through.
