Stronger than strong. Our cheese cutting wires for the Parmesan Pro. Specially made to cut those oh-so-hard Parmesan cheeses into small pieces. The cheese cutting wire is 0.8 mm thick. This is 0.2 mm thicker than the cutting wires we usually recommend. If you score well and turn the crank the right way, you can cut a considerable number of Parmesan cheeses into small pieces with this extremely strong cutting wire.
