That sounds like the opening line to a fascinating mystery or a classic infomercial!

There are so many everyday tools that have hidden features most people completely miss. A few classic examples:

• The hole in the handle of a frying pan: It’s not just for hanging the pan up; it’s designed to perfectly hold your wooden spoon over the pan so it doesn’t mess up the counter.
  
  
• The little arrow next to the gas pump icon on your car dashboard: It tells you exactly which side of the car the fuel door is on so you never have to guess at a gas station.
• The extra metal rivets on the pockets of your jeans: They aren’t just for fashion; Levi Strauss added them specifically to prevent the seams from ripping at high-stress points for miners and laborers.

What specific tool do you have in mind? Let me in on the secret!
