This funny looking thing is called the Rock, Chop & Rolling Knife, by Chef Randall.
The blade rotates through a casting so the entire force of your hand goes onto the blade – less stress, easier on the hands. Ergonomically designed, to boot.
It’s a vegetable knife, cleaver, chef’s knife, mezzaluna, dough blade, pie cutter, herb mincer, lettuce knife and it’s the best pizza cutter you’ll ever use all in one & it does so much more. Chef Randall
2 blades are included – a steel blade and a plastic one for dough. Comes with blade holder and blade lifter. $24.95
