The pizza cutter is a great matter, as long as you cut only thin frozen pizza or Tarte so. But should, however, thicker pizza American style or homemade pizzas that fail lush usually (in my case), are broken, there are significant problems because the round blade is too narrow. The result: the coating is no longer cut, but pushed over the dough.
Cleaning the pizza cutter is exemplary: the handle can be folded out easily, and the cutter is divided into 3 parts. Then the blade and the two handle halves have completely and thoroughly, so that no more food scraps stuck somewhere. Then, you insert the circular blade back into one of the two handle halves and closes all again with the second handle half.
