This pizza cutter is wonderful. I have several others, but I only ever use this one now. It gives you the perfect control when slicing pizza and allows you to apply a lot of pressure while cutting. I'd recommend it to anyone. If you use a pizza cutter often enough, its definitely worth the price.
My wife bought me one of these slicers for Christmas 5+ years ago and we have never used a knife or other pizza slicers since. Love this slicer and will buy another (because it broke). Closest thing to a pizzeria slicer I have found!
