Admittedly, the version the TSA catch seems like it was smaller than the original Star Trek weaponry. Here's what the archetype bat'leh, the legendary Sword of Kahless, looks like:
Bladed items are generally allowed in checked bags, but not carry-ons. However, the 2015 mini-bat'leth is actually not the first time the agency has caught someone trying to pack something like this in a carry-on: It discovered a similar weapon at LaGuardia in 2012.
And this isn't the only nerdy battlegear the TSA uncovered over the past year. A surprisingly number of people tried to bring batarangs -- weapons like Batman's bladed boomerangs -- onto planes, according to the agency's blog post.
