I still carry a Kubatan-Kubotan-kuboton (its spelled several different way) to this very day. I just recently discovered that it can't be taken on board commercial planes. I was
invited to be a referee and they absolutely refused to let me take it even with all of my ID and credentials in order etc. They did let the Captain put my bag with the Kubaton in it in the cabin with the crew. I think this Homeland Security has gone overboard on a lot of things and this might be a good forum to start
The no no on the Kubotans has been in effect here pre 9/11.. I got into it with one of those rent-a-cops that use to screen luggage when I tried to take mine through..I was just meeting someone as they deplane..Remember when you could do that??? The way around that is to pick up a ProTek key www.pps-selfdefense.com Its a great tool and it fits your hand better than the Kubotan..If questioned I tell them its the key to my gun locker at the department...
