Hold the back of the hard cheese firmly in your hand by wrapping your hand around the base of the cheese. Place the blade of the vegetable peeler against the top edge of the diagonal side of the hard cheese or the side you would like to slice. Draw the blade of the vegetable peeler down against the length of the cheese.
Carefully remove the slice of hard cheese from the blade of the vegetable peeler. Repeat the process for additional hard cheese slices. Remove cheese and oils from the vegetable peeler using a sponge and warm soapy water. Replace in drawer when dry.
