Place a dish towel on the kitchen countertop. Place the tip of the knife sharpener on the towel.
Hold the sharpener in one hand, keeping your fingers behind the protective butt of the handle. Grip the handle firmly.
Hold the knife in the other hand and press the heel of the blade against the steel above the butt of the sharpener.
Drag the edge of the knife down the sharpener as you pull it across at the same time. Drag the blade across and down the sharpener at a 10-degree angle.
Place the knife underneath the sharpener, and press the heel of the knife against the steel just above the butt of the sharpener.
Pull the knife down and across the sharpener in the same fashion to sharpen the opposite side of the knife.
Continue switching sides, sharpening each side of the knife 10 times.
