The instructions for my sharpener are a little different than the dritz brand. Hold abrasive disk in one hand. Place handle and blade assembly onto abrasive disk. Apply force and twist handle in one direction 10-20 times,depending on condition of blade. Turn handle assembly over, and sharpen reverse side of blade. Sharpen both sides equally. During the sharpening process, keep the sharpening disk moderately wet. After sharpening clean sharpener with a damp cloth.
My sharpener works great, haven't bought a blade in at least a year.
