The OXO SoftWorks Multi-Grater features two sharp stainless steel blades for quick and easy grating. The coarse grating surface is designed for semi-soft cheeses, butter, apples and more, while the medium grating surface works well with hard cheeses, vegetables and chocolate. The surfaces can be used separately or locked together for standup stability. Both graters feature soft, comfortable non-slip grips and feet, and are BPA free as well as dishwasher safe.
