Expert swordsmen - Star Trek: Website

Way to communicate contempt for your customers. If you’re in the business of selling decorative replicas of cartoon swords, you need to be in on the kayfabe. Nobody is expecting to take one of these to a real swordfight. What they are expecting, however, is to have a cool prop to show their friends, and it’s not unreasonable to expect the cool prop to feel like it’s not trying to fly across the yard if you swing it around.

If you don’t want people to touch the merchandise, the second sign is all you need.

Right? If you don’t want people handling your cool replica swords then maybe stop selling cool replica swords.
Pretty liberal use of the word “cool” there
Each to their own, of course, but the people who are picking them up to “expertly inspect the heft and balance” certainly think they’re cool.
But nobody thinks those people are cool.
Speak for yourself.
Not really, swords are cool, they’re generally fake for safety reasons, but that doesn’t mean they can’t be cool.
