Review on Enhanced ZWILLING 2-stage Pull-Through Knife Sharpener for Optimal Performance by Jim Ball

This sharpener sharpens perfectly. I have a set of Henckles meat blocks, but I mostly use a 6 inch chef's knife. I never knew how to use the included sharpener. As a result, my knives became so dull they couldn't even cut a pepper, let alone a tomato. I've tried other hand sharpeners but they didn't help. So I took this one hoping it would get better. After reading other reviews I gave each slot 20-30 tugs. The knife is better, but not what I was hoping for. Because of the ceramic groove, my knife went unevenly, like two stones came loose or something. I've used it a few more times and each time my knife is sharper than before. I still make at least 10 puffs per slot and the ceramic bricks seem to stay in place making for a much smoother ride and knife edge. Don't expect professional sharpening, but for my purposes of making a lot of salads, it's worth every penny. I downgraded a star because it should have room for kitchen scissors, something used in every kitchen.
