To slice food, we suggest using a sharp chef's knife. To hold your chef's knife properly, grasp the handle with three fingers and put your forefinger and thumb on opposite sides of the blade.
With a rocking motion, keeping the tip of the knife on the chopping board, slice down through the food at regular intervals. There should be no starting or stopping--try to achieve one continual motion.
Use your other hand to feed the item toward the knife. To do this safely, curl your fingers in and use your fingertips to grasp and move the item.
