This is a stainless steel, heavy duty pizza cutter that is perfect with our pizza cutting guide board. It can be used with pizzas that are 20 inches in diameter. The handle is made with high-resistant polymer and measures out 10 inches for easy griping. You can use the rocker traditionally or adjust the handle with a screw ninety degree and rock the cutter naturally and simply like a knife. This is the ultimate rocker cutter. You can cut pizza into slices or pieces or even in pre-cut groves.
