Chef’sChoice Hybrid Knife Sharpeners for 20-Degree Straight and Serrated Knives Combines Electric and Manual Sharpening With 100-Percent Diamond Abrasives And Precision Angle Guides, 3-Stage, White

If you follow their in-depth directions, it works great. In other reviews, showing stray scrape marks, not sure how you'd even do that with this. (competitor trying to sway sales I presume) In the box is a card, that gives you a web address to directions, some reviews complained it didn't come with instructions, and I guess they didn't look that hard.My old Boker steak knives were not only dull, but rounded! After giving them a session with this sharpener, I can easily cut paper from the tip of the knife down to the handle. Very effective and efficient. Some of my knives that were only a little dull, swiped them through stage three, and they came out sharp. Great sharpener if you read instructions.

This is one of the only decently priced sharpeners that works. I keep it in the cupboard and pull it out when the knives get dull.

Does it's job. Time will tell for how long.

My original 3 star review of May, 2019 is below. This edit date is May, 2021.After many uses, I have found the way to get better than utility edges consistently using this device. The key seems to be to lay the knife being sharpened against the side of each groove putting no pressure to press it down or raise it off the surface as you go. I lay the knife down and pull it it with two fingers to as not to change the sharpening angle.I give our 10" chef's knife 5 seconds per pass through doing each pass 5 times for a total of 20 passes (4 grooves). This suffices for normal 2 weeks dulling in our rather busy kitchen. I move shorter knives at the same rate so they take less time per pass.If you care about sharp knives, this technique will give them to you when you add a few swipes with steel before each use.**************************************I know you can get a superb edge using this tool since I managed to get one out of the eight knives I tried sharpening just now that way. The downside is that the edges on the other seven varied from disappointingly dull to all right but not great leaving only that one which stood out. This experience mirrors my other tries using this device. All our knives have a Euro-American bevel so it’s not that I’m trying to create an edge on some exotic Japanese knife which uses a different edge angle from that which this sharpener will deliver.I accept that learning to use a tool takes practice which I’d be willing to do but my failed edges don’t give me any hints as to what I did wrong so I can apply remedial action. I believe those who say they get perfect edges every time, but for me; it remains, after a month and a half sharpening experiences, a mystery. A very few of my edges come out spectacularly while the same number seems hardly sharper. The majority fall somewhere in between.In sum, it works but meh.

Let me start off by saying , I don't own any hundred dollars knives , if I did I would be looking at a 50.00 sharpener . I think I'm an average mid 50's person , and what I mean is my knives are like my plates, over 20 years old. In my kitchen I only need my knives to cut , that's it . I'm not shaving with them or trying to cut paper,I don't want my kitchen knives to be razor blades because I don't wont to lose a finger while washing dishes .My two filet knives started of in my tackle box and I liked them so much I moved them to my kitchen . Those two knives are both over 20 years old and never been sharpened . They were so dull that I stopped calling them filet knives . I have about 8 knives in the Kitchen and all of them are old and dull. My sharpener arrived on 2/20 and I was about to cook some 15 inch ribeye's and decided to sharpen all of my knives while my stakes cooked . I didn't read any instructions , i just pulled each knife through the slots about 6 times , looked at the blades , then washed and left to dry . When my stakes were finished I grab one of my over 20 year old filet knives and it sliced the stakes like hot butter and I smiled . Today after work I pulled of some potatoes and grab another knife and it was so Sharpe that I put it in the sink and used a peeler . I will probably only used it a few times in the next few years but I love it .

Sharpens okay but leaves "skuff marks " on the blade. The polisher doesn't do anything at all. Had an older Chefs Choice sharpener for years but it finally wore out. New one not nearly as good.

Even though it's electric you don't need that part unless your knife if bent. Best sharpener by far.

I guess I am not sold on this type of sharpener. It sharpens knives quickly but I have seen smoother jobs and if you don't take some care when sharpening you can make it ugly. So it works but not idiot proof and not like a professional might do but it is fast and sharp and I guess that is most of the battle.
