Using a sharpening steel requires some practice. It is important to maintain an angle between 15-20 degrees and to drag the entire cutting edge along the sharpening steel, from the start of the handle to the tip of the knife. How fast you do this plays no part.
Step 1 - the grinding angle: place the sharpening steel top down on a flat surface. Position the blade on the sharpening steel as shown, creating an angle of around 15-20 degrees between blade and steel.
Step 2 - direction of movement: drag the knife downwards along the sharpening steel in a slight arching motion.
Step 3 - sharpen both sides: repeat this motion on the other side of the steel to sharpen the other side of the blade.
Step 4 - repeat: repeat steps 2 and 3 five to ten times, alternating between the front and back of the blade.
