The OXO Good Grips 4-inch Pizza Wheel is a great little gadget to have in my kitchen. I am a huge fan of OXO products and this pizza wheel is no exception. First, the blade on this pizza wheel has remained sharp over a number of years. Friday nights are homemade pizza nights at my house and the OXO Good Grips 4-inch Pizza Wheel gets used on a weekly basis. The metal blade has remained sharp and it has not rusted. I am impressed with the quality of the materials that were used to make this pizza cutter. I really like the handle of this pizza cutter. It is made out of a non-slip, textured material that allows me to effectively maintain my grip on the pizza cutter. I like that it does not slip. With the right amount of pressure, you get clean, even cuts each time you slice a pizza. Overall, I am extremely impressed with the quality and performance of the OXO Good Grips 4-inch Pizza Wheel. Ease of Cleaning This pizza cutter is dishwasher safe. Durability I have had this pizza cutter for years and it still looks brand new and works like it did when I first bought it!
