Through market research, I found that many one-size graters take more storage space than a box grater, but they are easier to clean—box graters always hurt customers’ hands when they slide sponges in and clean the insides.

The 3-in-1 etched grater integrates three sizes of blades. It is hung on the wall to save storage space in your kitchen when not in use. Using it to cook, you hold the tab and switch until the wanted blades are in front of you, then push the button to lock the position. For safety during cleaning, Regarding cleaning, you can swipe both sides of the blades without danger of getting hurt.
