*scratching my head"

Prior to the fall of 2001, there was TSA and I flew with things much more effective than this on my person, without question or hassle from the officers hiered by the airports. Spring of 2001, I flew with a full-size multitool on my belt, a twiny swiss aremy knife of my key ring, a lockback knife in my pocket, and a lighter in my pocket.

So.... 2005, minus 2001, ingnoring a few months for simplicity, gives us four years. Less than four years. That is more than six years less than "over ten years".

Excuse me, but your errors are showing.
