A steel chopping board is a type of cutting board made entirely or primarily of stainless steel. Unlike traditional wooden or plastic chopping boards, steel chopping boards provide a unique set of features and benefits. Steel chopping boards are highly durable and resistant to scratches, stains, and odors. They are less likely to develop deep grooves or knife marks, which can harbor bacteria, making them more hygienic compared to other materials. Additionally, steel is non-porous, meaning it doesn't absorb liquids or flavors from the food being chopped, further enhancing cleanliness and preventing cross-contamination. The grating surfaces or attachments in a 4-in-1 grater typically include options such as coarse grating, fine grating, slicing, and julienne cuts. These different surfaces or attachments allow you to grate or shred ingredients in various textures, thicknesses, or shapes, depending on your specific needs.
