They've only hand-checked my bags once in the 20-odd flights I've had since 9/11.

Of course, they failed to notice the Swiss Army knife that I had in some small compartment of my carry-on, and had since forgotten about. Not so great of a hand inspection, I suppose.

I've since discovered the pocket knife (I was wondering where it went) and removed it, but it still makes me wonder at the quality of even the hand searches.
