Then again, you could probably shorten the time you spend in airport security lines by wearing your kilt while traveling.
I had packed my sgian dubh (traditional Highland stocking knife) in a bag that at the last minute I decided to carry aboard instead of checking through so I could be more immediately ready for performance upon arrival.
Didn't even think about it --this being the late 80s to mid 90s-- but the knife triggered an alarm in the x-ray machine and I spent a few uncomfortable minutes until the agent decided it was okay: the blade was slightly shorter than the limit of the time. Stupid: my car keys were probably a deadlier weapon than that costume knife.
