OXO Good Grips Box Grater
This box grater is one of the best you can buy and my favorite. It has four sides that allow you to slice, and grate with three different options. The grater blades are sharp and sturdy. It can be used with cheddar, mozzarella or hard and aged cheeses like Parmesan. It also comes with a storage container where what you grate collects in the bottom. As an extra bonus, the storage container stores inside the grater when not being used. It is also dishwasher safe.
