OXO’s newest Pizza Wheel features a clear plastic wheel that won’t damage your non-stick pizza pan. The edge of the wheel is tapered so it slices as well as a metal blade, even through thick crusts and heaps of toppings. And the slick surface of the plastic wheel is less likely to have cheese stick to it. The plastic wheel is safer than a metal one, and a thumb guard and soft grip further protect your hand. Dishwasher safe for easy cleaning.
