The fine folks at Loyld’s have a neat cutter they call the “Equalizer”. Envision a nice rocker knife that automatically cuts each slice at the same time. They are available in most any slice configuration, and yes while they might seem a tad pricy, remember that it’s Loyld’s, it’s going to last forever and make your life easier!
We played with these at Tom’s “Pizza Camp” a few years ago when they just came out. It’s worth your look, and leaves near zero room for employee error!
