We’ve created a new challenge for you here on PopSci.com, whereby you can show off your obscure knowledge of tools and, well, win new tools!
Here's how it works: We'll post a picture of an object, maybe a clue or two, and you guess what it is in the comments section below. The first among you to guess correctly will win the prize. This week, it’s a 20 ounce Stanley FatMax hammer. Pretty sweet.
