Per the Pampered Chef website: "Our ergonomic handle makes it even easier to create fancy vegetables and cheeses, and mince herbs. Includes a protective storage cover. Dishwasher-safe." and "Using the Crinkle Cutter is a decorative way to cut potatoes and lots of other vegetables. To use, place one end of Crinkle Cutter on the Cutting Board and use a rocking motion to cut through foods. Always keep the end of the Crinkle Cutter closest to your body firmly anchored to the Cutting Board and fingers out of the way." Check out the Pampered Chef website for any more detail. Thanks for asking! Have a great day :)
