In the mid-00s I had a Leatherman multitool with a knife. I was constantly forgetting to take it out of my pocket before going to the airport, and never once did the (then-fairly-new TSA) even mention it, let alone do anything about it.

I finally lost it in 2008 or so when a bouncer at a club wouldn't let me in with it (and I had parked quite a ways away and waited in line for too long for me to consider going back to put it in the car). So... nightclub bouncers are more effective at screening weapons than the TSA.
