A pizza cutter is a kitchen tool designed specifically for slicing through pizza. It typically features a circular blade that rolls over the pizza's surface, allowing for clean cuts without disturbing the toppings. Some models have a handle for better grip, while others may be shaped like a wheel or a knife. Pizza cutters come in various styles, including rocker cutters, which use a rocking motion to slice, and wheel cutters, which roll across the pizza. They are made from materials like stainless steel for durability and are easy to clean, making them a popular choice for both home cooks and professional chefs.
