No, this grater is not dishwasher safe. Because it is crafted from pure copper, you should hand wash it gently with mild soap and dry it immediately to prevent oxidation or damage to the metal.

Copper is a softer metal than stainless steel, which allows for a different, often smoother grating action. Many chefs prefer copper graters because they are less likely to bruise delicate ingredients like ginger or wasabi, helping to preserve the texture and flavor of the food.

The grater features two distinct grating surfaces, allowing you to switch between textures without needing a second tool. One side is typically designed for finer grating, while the other offers a slightly coarser texture, making it versatile enough for everything from hard cheeses to aromatics.

Yes, as a natural material, pure copper will develop a patina over time with exposure to air and moisture. This is a normal characteristic of the metal and does not affect the grater's performance, though you can use a copper polish if you prefer to maintain its original shine.

At 0.75 lbs, it has a substantial, high-quality feel without being cumbersome. The weight actually provides a nice stability on your countertop while you are grating, so it doesn't slide around easily.
