Our Genuine Copper Grater is a choice of Chef Kuniko Yagi of Pikunico in Los Angeles! In Eater, she describes how and why she uses Japanese copper graters. Perfect for ginger, garlic, citrus zest and more, this copper grater requires less force to grate and is built to last for decades. Our handmade version from Niigata is currently sold out, but you can sign up here to be notified when it's back in stock, or stainless steel grater is available here.
