This pizza cutter is equipped with a five inch blade of high-carbon stainless steel. This is important for several reasons. Many pizzas are made with tomato-based sauces or often tomatoes as toppings as well, and a pizza cutter is especially susceptible to corrosion and staining from the natural acids in tomatoes. Since the Sani-Safe line of pizza cutters are all designed with high-carbon stainless steel, the operator can use it time and again without concern about its longevity. The Grip-Tex handle adds a solid, non-slip grip for comfortable use.
