Bests & Worsts Reviews from Amazon

I also have the ChefsChoice model #463 for Asian knives and wasn't too happy with it until I found out that I was using it totally wrong. I found out from one of the reviews that these sharpeners require a sawing motion to sharpen knives rather than swiping in one direction. I didn't have the user instructions handy, so I downloaded the .PDF instructions. When I used the sharpener correctly, it worked surprisingly well. So, I decided to order this sharpener that works for both Asian knives and Euro/American knives. I have an electric sharpener that has good reviews, but these hand sharpeners seem to work more effectively, and they are much more handy. As soon as i got this sharpener, I tried it out on some old Chicago cutlery steak knives we have. They were so dull, I could not have cut my finger if I wanted to. It took 20 swipes on the Euro/American slot and 10 on the polishing slot, but these knives were razor sharp and passed the paper test. Then I tried this sharpener on one of my most used Shun knives using the Asian slot and the polishing slot. The knife was restored to like new sharpness. This sharpener seems to do a lot better job of sharpening knives than my electric one. If you decide to get this sharpener, you have to keep in mind that you need to put 4-5 pounds of pressure on the knife as you sharpen it. You also need to use a saw motion rather that the one-directional motion used for most sharpeners. If you use it correctly, this sharpener will sharpen your dullest knives. UPDATE 04/03/20: I have been using this sharpener for about 2 years, and it still sharpens my knives as well today as the day I bought it. I know some people prefer sharpening stones or rods, but when using these, you have to make sure you use them at the correct angle of the blade. If you don't, you can easily damage the blade of an expensive knife. By using this knife sharpener, I only nee to use the correct slot for the type of knife I am sharpening and then use the honing/polishing slot. Once I sharpen a knife, I have to be careful so I don't accidentally cut myself. A couple of times, when I was in a hurry, I lightly touched the blade of a sharpened knife on my hand or finger, and didn't realize I cut myself until I saw the blood. UPDATE 06/11/22: I have had this sharpener for over 4 years, and it still sharpens my knives as well as when I first got it. I swipe the knife back and forth in the appropriate slot (Asian or Euro) 20 or so times, and then do the same using the honing/polishing slot. After sharpening, even the less expensive knives are razor sharp. As mentioned previously, after sharpening knives, even the slightest touch to your skin will cause a cut. Most often you don't realize you were cut until you see the blood. If this sharpener ever wears out, I will definitely buy another. I have given away the electric sharpener I had as it never worked as well as this one. I hope this review was helpful for you. I will update this review if my opinion changes.
