Most kitchen gadgets don't come with manuals, but maybe they should. Time and time again, humans have demonstrated a knack for taking something simple—say, a can opener—and finding a way to use it in the most difficult and least-efficient way possible. (Hint: The rotating handle should be placed on top of the can, not off to the side.)
Well, the internet has once again stepped in to save us from ourselves. There's apparently an easier way to use a standard four-sided cheese grater (a.k.a. a box grater), according to a short video that was originally uploaded to Instagram by Menu World. Instead of holding it vertically in one hand, you lay it down horizontally on a table or counter and start grating your cheese from side to side instead of up and down. This prevents the grater from moving around while you hold it, and it's a little easier on your arms. (In a similar vein, you can also apply a coat of cooking spray to the outside of the grater to make it less of an upper body workout, and this is especially recommended if you're grating sticky cheese.)
The cheese grater hack has been going viral on social media, so don't feel bad if you never thought of doing it this way—lots of other people haven't, either.
This method is also helpful because the cheese collects inside the grater, providing a handy visual guide for figuring out how much cheese to shred. When it's grated directly into a large bowl with other ingredients, it can be a little harder to judge.
Here's one final tip for your next cheese-infused dinner: Try using an old toothbrush to clean out all of the grater's little holes. It will save you some time (and perhaps prevent minor grater-related injuries). For more tips like these, Mental Floss has a couple of guides for awesome cleaning hacks.
