I always sail through TSA with this!!!!
Thought I'd send a quick note. I just went through security at DFW (Dallas-Fort Worth Airport) and had zero problems -again. They didn't even look at it. Probably been through 2 dozen checkpoints so far.
You can't really tell its a tool, unless you really look at it. It just looks like a key.
Handy too. Can't tell how many packages and boxes I've opened with it.
I take it everywhere now and hand them out to my clients.
