Yes, so far they haven't even checked mine at the gate this season. Last year they checked it twice, the first time being rather detailed scrutiny, but when I showed that they could pull with all their strength while I leaned away from the pull with all of mine, and the hilt could not be removed, they allowed it. After that they've either not noticed, or just checked quickly.
It's the inconsistency that bothers me. If it's clearly fake, I don't see what the problem is. Though I suppose they'd make the argument that they can't train all their security guys to know where to draw the line, so it's easier to ban everything.
Silvanus, I'm sorry we missed you! We kept our eyes open all day, but of course it's a large enough site that you can easily end up circling on opposite sides and never spot each other.
We took a group photo on Saturday with all of the armored folks we could muster on short notice.
