This pie cutting is no exact science and making evenly-sized pieces by sight is often too daunting a task for anyone. Made of aluminium material. However, using their 9-cut pie marker anyone can mark equal-sized pieces so everyone gets their fair share. Each arm has nine teeth to clearly mark the cutting path, making it easy as apple pie to cut every an even slice. This marker is great for any restaurant or café serving up comfort food, one slice at a time. Measures 24.1cm diameter.
