2015: All my Henckel chef and steak knives were dull after years of neglect. I’d done the whetstone honing process a couple times in the past but that was getting old. So, being picky and figuring you get what you pay for, I thought I’d get a top-of-the line Chef’s Choice or Wusthof electric knife sharpener for $150. Then I saw this manual sharpener for $25 and thought, “What the heck, Henckel wouldn’t sell junk to sharpen their own knives, and if it doesn’t work I’m only out $25”, so I bought it. Impressed by the “heft” when I took it out of the box … solid. The “sharpeners” are simply one pair of slightly overlapping wheels in each slot, steel carbide wheels for the Rough #I slot and ceramic ones for the Fine #II slot.For neglected knives, you simply draw the knife through the Rough slot a few times with only very slight pressure until you feel no more of the initial “roughness” there, Then you do the same in the Fine slot until it glides smoothly through that also. That’s it. My 16 knives took a half minute each and each passed the final “slice the printer paper” test. Once you get them in shape, a couple quick times through the Fine slot returns a razor edge in seconds. Tap it in your trash can or sink occasionally to empty metal particles. No comparison to that timeworn method of stropping them using a round “steel”. That said, if your knife blade is really bent over, you’ll know it when you pass it through the Rough slot, so that’s the time to use your round steel first to reset the edge before then sharpening it. Absolutely not for serrated knives or one-sided blades like santoku’s with one edge or scissors, and undesirable for Asian-type knives, which have a sharper 14 degree bevel per side vs. American/German knives with a 20 degree bevel.I don’t think the electrics do anything much different since they have the same slot-with-sharpening-wheels design … and you still have to pull the knife through the different slots, so they would seem to only add value for high-volume restaurant use sharpening of dozens of knives every day. I.e., why spend a $150 instead of $25, and another counter appliance to do the exact same thing?

I often make sweet potato treats for our blue-brindle Cane Corso (Italian Mastiff), named Dante. After buying a one pound package at the vet for $15.00 I figured that it would be much more reasonable to buy the sweet potatoes myself (for between 69-99 cents per pound) and dehydrate them at home. So I invested in a $60.00 Nesco dehydrator and started producing sweet potato treats. The only problem I encountered was the difficulty of cutting the potatoes to the proper width without removing any of my fingers. Normal (cheap) chef knives dulled up immediately, causing me to really bear down on the knife and upping the odds of a really bad cut. So I started searching for a knife that would make the job of cutting hard vegetables much easier and therefore safer.My choice was the Zwilling J. A. Henckels Twin Four Stars Series 7-inch Santoku Knife with the hollow edge. That’s kind of a mouthful, but I found a great deal on the knife with a cutting board for only $49.95. This knife out of the box was so sharp that it even looked dangerous. It was easy to shave hair off my arm and it sliced through a sheet of paper like it wasn’t even there. Trying to feel the sharpness of the blade with your finger was a recipe for disaster. Obviously I had found the right knife. After using it on probably 100 pounds of sweet potatoes, the edge wasn’t quite as sharp as it was when brand new. It still could shave hair off my arms and it could still slice into a sheet of paper, but it took a little more effort and more careful placement.So obviously I needed the proper sharpener to bring my knife back to the superior cutting tool it originally was. When I returned to the knife’s product page I noticed that this Twin Sharp Duo Knife sharpener was paired with my Santoku knife for a potential purchase. Knowing that different knives have different cutting angles, I wanted to make sure that I was using an appropriate sharpener and it wouldn’t ruin my knife. When I read the instruction manual (I guess that I’m still old school) it clearly said that “This knife sharpener may only be used for uncoated knives with a straight edge.” At the end of the manual it says “The pre-set of the sharpening wheels is for household knives only. To sharpen Oriental knives, a different angle may be necessary.”Since the Santoku knife I have is an Oriental style made by a German company, I double checked the product page and saw a comment from a Zwilling representative who said that the angle on this sharpener does not match the angle used on their Santoku knives. Just to be sure, I pulled my knife through the “I” slot with no resistance. Then I pulled it through the fine ( II ) slot and felt and heard a lot of chattering. After pulling it through I tested it on my arm and on another sheet of paper. This demonstrated that the blade had been sharpened BUT the knife’s edge was now ragged looking and had obviously shed some of the blade’s steel. Continued use of this sharpener would no doubt eventually ruin my expensive blade.I did use it to sharpen some old (and cheap) Chicago Cutlery and Sabatier knives that had dulled up considerably. It did the job and brought the edges back to reasonable sharpness but not to a degree that I expected.

The Zwilling knife sharpner does a good job maintaining the knife’s edge. It sharpens it if it’s dull. Only thing is it cannot get it sharp to its original sharpness. You would need to use another device.

I tried it on two dull knives, it’s like it revived them.A definite buy for everyone person who cooks often.

I was skeptical buying this as i had a bad experience with a honing stone I bought earlier. However this sharpener exceeded my expectations. I sharpened two chef knives using this. It was easy to use and knives are sharp now. I will keep an eye on how long sharp edge lasts and durability of the product.

Donβt expect those razor sharp edges, but it does an OK job at sharpening. Unit is a little large on the counter and the action of the stones is a little loud and clonky. Iβll continue my search for the ideal sharpener.

I had a similar sharpener in the past and really liked how it worked so I’m glad this one is the same quality as my previous one that lasted many years.
