I have this sharpener. Absolutely love it. You have to make sure that you oil the sharpener stones before each use. Remember it has a fine set of stones as well as a course set. Use fine to actually sharpen your blade. The course stones are used if you have small nicks in the blade. I sharpen my blade at least 3 times a week to keep it sharpened. Sometimes more depending on how much I am using the blade. I have had my sharpener for over 2 years and I don't regret purchasing it.
