I remember either 1999 or 2000, flying from Sea-Tac to Tucson. Spyderco in my pocket. No problem. Go back to Tucson to fly back home to WA, and the assholes wouldn't let me through security with it. Of course, I argued, saying it wasn't a fucking issue for Seattle, when I flew the thing DOWN HERE, and if you have some kind of regulation saying it's illegal, then SHOW ME. They pulled me off to the side, and told me if it wasn't serrated, it wouldn't be a problem, but it is... Take it back to the counter, put it in a labeled box, and have them put it in the checked baggage on the plane. Got my fucking knife home. Communists. My, how times have changed. I still have that knife, too.
