I use my pizza cutter to cut my dumplings for chicken and dumplings. Also good for cutting homemade noodles.

I love the picture you have beside the comment cleodaisy. That would make a beautiful applique, could you share?

I try to make more than one use for all of my gadgets. My grapefruit spoons are great for scraping seeds and membrames out of hot peppers and also if you just cut the top off of a kiwi you can use the spoon to eat the insides without peeling it. My cake turners/spatulas are also used to chop kids food into small pieces making it easier for them to eat or be fed to. I bought a plastic long rounded pizza cutter years ago for the kids and it cuts so many things in my kitchen and does it with a lot of ease that a knife wouldn't always do. Those are just a few of my multipurpose tools.

I've been using the pizza cutter on fudge for years!...it make it such a clean cut. Works well on brownies, too...but they must be cool enough or they accumulate on the wheel.

I couldn't make homemade marshmallows without a pizza cutter dusted with powdered sugar!
They stick to EVERYTHING...including each other!

A plastic knife from a fast-food restaurant is great for cutting fudge and brownies without feathers or tears.
