I am notoriously bad at selecting the right size wrench, and sometimes it comes back to bite me. I was recently shown this trick by a buddy of mine, and it is a lifesaver!



*Note: while this is a very useful tip, I would not recommend using it in every situation. In some cases (like if you're working on your bike or car) it's better to make the trip to the store to buy the correct tool.
