The unique handle on the Progressive Folding Pizza Wheel gives it more versatility than a traditional cutter. With the handle in the closed postion, the wheel functions like a traditional pizza wheel, but when the handle is opened, you can use both hands to provide to cut through tough crusts. The wheel itself is covered with a nonstick coating that helps to prevent cheese and toppings from adhering to the cutter. The Folding Pizza Wheel is also terrific for slicing quiches, dessert bars, and brownies. Dishwasher safe.
