If you thought your everyday average stapler was capable of one thing and one thing only, you were right, but there's a little secret hidden within the metallic depths that few know about.

There's a little metal plate on the bottom of your stapler, and what do you know! It moves, and can seemingly control the width of your staples. This video by Sarah Barlow better explains how this nifty little trick works.
