If you happen to run into Jonathan Hirshon, president of Horizon Communications, ask for a business card. It's made of steel.
For the past two days, we've been trying to figure out all the many uses for it. It's sharp enough to cut carrots. If sharpened a bit more, it could be fashioned into a Ninja star. If this were the '80s, it would have been a status symbol for drug dealers in Miami.
The word "Horizon" isn't painted on the card either. It's a stencil, so you can also use it to decorate Christmas cards. Here, it's pictured stuck in a Special K Blueberry bar from the CNET 6th floor vending machine.
I also used it to clean crumbs out of my keyboard.
"It could be used as a weapon," Hirshon joked. So far, he says, he hasn't been stopped in airports.
Update, May 24, 2017: Hirshon writes that the infamous business card was made of acid-etched steel, not aluminum as we originally reported.
