Review on Chef'sChoice EdgeSelect Professional Electric Knife Sharpener - 20-Degree Diamond Abrasives, Precision Guides - Straight and Serrated Knives - Made in USA - 3-Stage - White by Lisa Chenault

I bought my chef's 120th knife in March 2016. We have about 15 knives, including steak knives, which we use regularly and sharpen every 4-6 months. The results are amazing, I couldn't be happier! In the beginning, it took several attempts to master the right technique. I would say there are 3 main methods. First, in most cases, the impeller itself would only be used once. Stone #2 and a buffing wheel were used for subsequent sharpening. Second, it requires a light pull, not a high-pressure pull. And third, in most cases, it only takes 2 or 3 moves to get the job done. My experience after three years of use has been great and I highly recommend this sharpener.
