Utility Knife Cap
On the end of your utility knife, that plastic cap is an important part of it. If you pull it out, you’ll find it attached to something. That is extra parts for the knife blade. When your blade becomes too blunt and is losing its sharpness, you can just break off a piece of the extra and pop it into place for a brand-new, sharp utility knife!
Stapler Plates
The metal plate on the bottom of your stapler actually has a name. It’s called an anvil. If you turn your stapler upside down you can adjust it by spinning the wheel until it lines back up with the square it sits on. Use this if you ever want a “temporary staple”. It will push the arms of your staple out instead of in, allowing you to pull it out easily later on.
