All the models we looked at today are manual meat slicers, meaning they require the operator to apply force for them to cut. On the other hand, Automatic slicers don't require a human operator, and once the meat is loaded into the food carriage, it begins slicing automatically.
Automatic slicers are almost exclusively reserved for commercial settings and are very rarely found in a home setting. Manual slicers are the type of slicers one would expect to find in a supermarket or deli, and all food slicers featured on this list fall into the manual category.
