I came across this wonderful pizza cutter on Amazon and it is fabulous. Immediately as it arrived, I threw away my antiquated pizza wheel.
I have, many times in the past, gotten frustrated while cutting my pizza, due to the poor technology of the pizza wheel. My pizza slices were cut jagged, and the cheese had peeled off.
This cutter has a 14 inch curved blade that rocks over the top of your pizza, similar to how it's done in professional kitchens. It's a piece of cake to clean and has a hole in case you want to hang it on your knife rack.
If should absolutely try this, it's a great price for a great improvement in your kitchen.
