I've been a professional chef for 18 years and have used the Lansky sharpeners even prior to that. I find that they are a great way to keep my knives razor sharp and the guides keep the edge at the exact angle needed to keep your knives in great shape. The only drawback I have found is that the plastic encasing the stones can sometimes crack from constant tightening of the screw. The new diamond hones are working great.
