JohnKSA - I remember the case. The guy walked, largely because he actually was a teacher carrying a bunch of books. Context is everything. Before I'd thought of the possibilities I went through post-2001 airport security with one in my carry on book bag - along with eight or nine tomes - in the US and even across the Canadian border. If I'd had it in my back pocket there might have been trouble. Similarly, I've flown with a Bodhran (Irish frame drum) and the beater that you use to play it. Yes, it's roughly the same size and shape as a number of pocket sticks like the kubotan. Packed with the drum and a couple of flutes it wasn't a problem.
