This popular pizza cutter is easy-to-make. It has a durable, thick stainless-steel blade which is beveled to a sharp edge. A stainless steel thumb guard keeps fingers safely away from the blade and helps you press down to cut.
Drill a 1/2" hole for the tang then turn a handle to a suitable length between centers. With the 4" diameter inch wheel, the overall length can vary depending on how you prefer your handle. (Hand wash)
