KitchenAid Gourmet 4-Sided Stainless Steel Box Grater with Detachable Storage Container, Black (KN300OSOBA)

Four grating surfaces plus a catch-and-store container — grate, measure, seal, done.

KitchenAid's box grater covers fine, medium and coarse grating plus a slicer across its four stainless faces, and it sits on top of a detachable 3-cup container with measurement markings and a lid. That means cheese for tonight's tacos lands measured in its own storage box instead of scattered across a cutting board.
