A box grater provides more stability and grip when you're turning a chunk of cheddar into shredded cheese, but they pose some challenges when it comes to cleaning and storage. So as the name implies, the Flexy grater starts off flat but can be rolled into a three-dimensional shredder, so it's easy to hold and can be slipped into the shallowest of drawers.
Made possible through the use of harmonic stainless steel just 0.2 millimeters thick that remembers and returns to its flat shape, the creators of the Flexy had to experiment with the size and shape of the tiny blades to ensure that it was indeed able to bend without permanently getting warped. The original design won a much deserved Red Dot Design Award, but it's finally been turned into an actual product—it can be yours for around $40. [Flexy via Red Dot Design Awards]
