[This review was collected as part of a promotion.] Great product. Easy to use. Sharpened my knives easily and better the my old motorized sharpner! It is suitable for both standard and Asian knives. Really works for me. Extremely affordable and high quality!

[This review was collected as part of a promotion.] According to the instructions, it takes about 20 pulls. It took me 60 pulls still not really impressed about it. I bought this because I own a 7 pieces of knives set and are very happy with the knives.

[This review was collected as part of a promotion.] I was very skeptical. I've never used a knife sharpener before, but figured it couldn't hurt my dull knives. To my surprise, the zwilling 4-stage knife sharpener outperformed my wildest expectations. The knives are like new again. FYI: I also watched a YOUTUBE video to see exactly how to use it & it was easy! It only takes a few seconds per knife.

[This review was collected as part of a promotion.] This sharpener is perfect for someone like me who cannot consistently maintain the correct angle on a traditional whetstone. I sharpened both zwilling knives and cheap kitchenaid knives back to slicing thru sheets of paper easily. It took all of 2 minutes to sharpen did not require any complicated soaking or technique like a traditional stone.

The sharpener was bought six month ago and it doers not works. Knives are dull and try with many strokes to sharpen the knives. Very disappointed with this tool, and for this brand! After some inspection, it looks like the stones are rounded at the very bottom, not cutting the edge of the metal as it should.

[This review was collected as part of a promotion.] Works good if your knifes are relatively sharp and in good condition unfortunately wouldn’t take the knicks out of a couple of my knife blades. The knicks are my fault for putting the knives in the dishwasher and not hand washing and drying right away. I was hoping this would get rid of sharks teeth (knicks) on those blades but I’ll either have to get them professionally sharpened or get a new set.

[This review was collected as part of a promotion.] Keeping knives sharp with a quality edge is no longer a chore. This is great product that takes less than a minute to get a knife better than factory sharp. The coarse slot removes any nicks and the fine slot completes the task--only a handful of strokes to get it done.

[This review was collected as part of a promotion.] I used the 4-stage knife sharpener on some old knives and this thing really did the trick. It also sharpened my pro zwilling chef’s knife back to brand new sharpness. I’m very happy with this product.

I am usually not a proponent of pull through sharpeners. They are often misused. However the ceramic rods that do the work in this sharpener actually work! They don't make me second guess if they are working, and therefore I don't have to run my knife through it a million times, and ruin my blade. Make sure you know how to use it correctly and you will enjoy having this to maintain your knives.

[This review was collected as part of a promotion.] This is a great, easy to use knife sharpener. I also like that you can use it whether you're right or left handed. The grip is comfortable to hold. It is very stable. It sharpens my knives very well.
