Any cutting implement will get dull over time. People use cutters to make sure that pizza can be quickly and evenly divided into slices. You need them to be sharp. The reason for this is you want a clean and quick cut through the crust, topping (like cheese) etc. You want it as sharp as a knife. Like a new set of kitchen knives. So its essential to sharpen your pizza device of choice.
How to sharpen a pizza cutter? Here we have outlined various methods like stone, belt grinders etc. The best way (my preferred) is using a pizza cutter sharpening tool as its just quick and easy. If you don’t want to spend the time sharpening most pizza cutters you can just get replacement blades. Blades are easy to fit and allow you to quickly cut pizza again.
Of course you can just use a knife to cut your pizza and the blade is arguably easier to sharpen. I often cut mine straight on the pizza stone.
If your pizza wheel is sharp then cutting pizzas takes little effort. You will have pizza slices in no time. They also have many other uses. Id say its one of my essential pizza making items.
