Pizza cutter wheels are the most well-known method for slicing pizza. A sharp wheel is attached to a handle and can be easily rolled across the pizza, quickly dividing it into individual pieces. There are some factors to consider when selecting a cutter. One of the first things you want to consider when selecting a pizza cutter wheel is the actual wheel diameter. Generally, they are two to three inches in diameter, but if you are making deep dish or stuffed pizza, you will want to make sure the wheel will actually penetrate the pizza. Handle material is another thing to consider. The handles can be made of metal, wood or plastic. The type you want is really a matter of preference, but plastic handles are usually easier to grip than metal or wood. A final feature to look for is a finger guard. This is a small metal plate between the blade and fingers that protect the fingers from the hot toppings as well as the sharp blade.
