Wüsthof Precision Edge 4 Stage Knife Sharpener, Black/Grey, 2944-7

I used it for my Zwilling knife which was a bit blunt Didn't notice any noticeable improvement , despite using the coarse and the fine slots more than twice . I guess the main issue is that it's Made in China and probably has no quality control

On peut facilement affuté des couteaux normaux, à dents et asiatiques. Facile d'utilisation. Robuste du Wusthof tout simplement.

I've used this sharpener on the newer Wusthof Classic Chef knife and it works perfectly. The standard cutters are for that particular line of knives, where the bevel on each side is 14 degrees. It also has cutters for Asian knives, and this really means ASIAN, more on the lines of Japanese Damascus steel blades that are very expensive and the metal is very hard. Those cutters are not for something like an any brand Santoku knife. It's for high quality, expensive Asian knives made from very hard steel, that holds a fine edge while you're working. I've used the standard cutters for Mercer Genesis blades and it works really well, but the metal is a little softer I believe so you need to hone after every use, which is easy enough since that's what the ceramic cutter does. I find if I do a bit of cutting through harder food stuff such as carrots then I have to sharpen the Mercer blades more often. Once again though, this pull through is absolutely wonderful and easy to use so I don't mind using it with those blades. I also have a couple of fillet knives that I use strictly for fish, and I can use the Asian cutters for those blades, and I hone every time I use the blades. I have a couple of other blades I use with the standard cutters and once again because the metal isn't as good as the Wusthof Classic line, I have to sharpen more often. The point is though, it's easy. While you're learning to use this, which requires a certain amount of pressure applied with your hand when pulling through, after sharpening and honing, do a paper test, where you pull the blade while pushing down on the edge of paper, to test your edge. This will let you know if you need to do more work, maybe adjust what you're doing, ensuring you're pulling through at a 90 degree angle, etc.... It's easy to use, but you still have to pull a knife through these correctly to have a consistent edge across the length of the blade. When going through paper you should have a clean cut, with no tearing or ragged cutting. It should be a clean cut along the entire blade. That's when you know you're sharpening the entire blade correctly. Feel free to experiment with different blades, but do know that many blades will not retain such a fine edge very long and you'll at least need to hone on a regular basis. But once again, it takes me about 30 seconds with a few pulls through the ceramic cutter to recondition the edge so for me I don't mind and I like the fine angle (14 degrees) for most my cutting. Many cheaper or older blades were originally set to 20 degrees, so taking it down to 14 degrees is a bit of work. But I also don't have cheap knives. I have some that are less expensive but they're certainly a step up from the bargain knives you buy in many stores, or on Amazon when you see a low cost set.

It is a good product. But it doesn’t sharpen the knives as I expected. May be due to the type of knives I have.

I recommend going to your local knife store for regular care. This sharpener isn’t that good.

It is very difficult to sharpen a high quality steel knife. I discovered this problem after I purchased a few Wusthof kitchen knives. Regular sharpeners just don't get the job done. The design and materials and style of this sharpener is perfect to restore Wusthof stainless blades to their original sharpness and requires no special expertise. Thank you for a quality product that can handle the most challenging sharpening tasks.
