Best Electric Knife Sharpener

Finding the Top Rated Electric Sharpener

Electric knife sharpeners have the advantage of speed due to the automation of the grinding, usually 1 to 2 minutes from start to finish. If the knife just needs a touch up, then the process may only take under 30 seconds!  This is one of the reasons that electric knife sharpeners are ideal for kitchen cutlery applications, even gourmet cutlery made with very high quality metal.  Most of the models come with two stages, coarse and fine, while the best models have three or more stages.  The three to four stage models typically allow the user to sharpen very dull blades more quickly or enable the knife blades to be honed very finely.  Avoid models with only 1 stage since they typically are fairly coarse and remove more metal than necessary and shorten the life of your knives.

Most basic, economy models have composite sharpening stones and most models currently do have diamond based abrasive stones. It is typical to have a very fine or straightening stage made of tungsten carbide which serves the purpose of steeling the blade – that is to say the microscopic cutting edge is realigned and straightened.  Some models can sharpen serrated knives but the economy models usually will not so be sure you check the manufacturers documentation. One of the other advantages of electric sharpeners is that the angles are non-variable or fixed, providing a consistent and precise angle.  Most electric knife sharpeners of high quality have a 20º or 15º sharpening angle, with a total of 40º or 30º inclusive.  The 15º angle is designed for Japanese style knives while the 20º angle is for European style knives. Lower quality knife sharpener manufacturers may not specify the sharpening angle.

This table contains a list of the top 5 best electric knife sharpeners as reviewed by actual users,  with consideration to the features, durability, and cost.

    This is a very good summary! I am trying to determine if I should get the Chef’s Choice 120 or the Chef’s Choice 320. Cost is somewhat a factor but I don’t know if 3 stages is really worth the extra money over 2 stages.

    Any tips?

      Hi Jason. Thanks a lot!

      It partly depends on what kind of knives you think you will be sharpening. Do you think you may have some blades that are very dull and may benefit from the extra coarse stage? If it were me I would definitely save up a little bit longer and get the 3 stage version. I think it is worth the extra money and you will just have to buy one sharpener so you should be trying to get the right one upfront. Does that help?

    Hey Billy. Yeah, I do have some pretty dull knives so I think the more aggressive stage will be helpful. Also, I’m thinking about, like, getting some older knives and maybe cheaper knives from the thrift stores to restore to a sharp condition. I also have a couple pocket knives that I’m pretty ROUGH with so they need some extra TLC and all that. Thanks again, Billy, for the really good info.

    I’m really not sure which sharpener to get. I will be sharpening kitchen knives exclusively since my other half has his own sharpening system. We have a variety of very high quality knives that we’ve acquired since we got married. I think I want the Wusthof because of the sharper angle. I even have a couple wusthof knives. Should I be concerned if the angle of my knives is not 14 degrees? Can I make my other knives sharper? What will that do to them?

      Lindsey – Good question. Get the Wusthof. :) It’s awesome for the application that you have described. Since you just have kitchen knives, you’ll be able to just have them very sharp at the 14º angle. If you do have any kind of cleaver or other knife that will see some rougher action (like cutting near bone), then you might want to have your husband sharpen those to a little more durable angle (like 25º-30º).

      So, to answer your questions. Yes, you can sharpen the other knives to an angle of 14º though you will have to take a little more time to reprofile those blades. Yes, you can make the other knives sharper. The result will be a sharper knife edge that will be a little bit less durable. Since you will have a very nice knife sharpener, it will not be an issue to quickly resharpen those knives.
      Good luck!

    I am thinking about getting the Presto since it’s so cheap and it seems to have good ratings. But I was also seeing how all the other top picks are Chef’s Choice and that’s what my brother has, plus the folks at Williams Sonoma use that too. Should I maybe try to save up to get the Chef’s Choice 220 over the Presto? Maybe even for the 320? Is the Chef’s Choice 320 that much better than the 220? My grandma said you get what you pay for… thanks!! mandy

      Hi Mandy – I would say you should probably save up for the Chef’s Choice models. They tend to have higher end products with Chef’s Choice so I slightly trust their quality over Presto. Don’t get me wrong the Presto will do the job but I am almost certain that the Chef’s Choice will last longer. I would definitely hold out for the 320 model since it is not one of the hybrid models. Also, check out the 100 series, specifically M110, since they might be in the middle price wise. The bottomline is that I would go for the 320 due to the 125 Watt motor, where the 110 has 71 Watts and the 220 has only 42 Watts. I think your grandma is right!

    Hi! I’m trying to decide whether to go with Presto’s 2 stage or 3 stage electric knife sharpener? Any advice would be appreciated- thank you!

    Reply
    1. Billy

      Hi Lindsay, I would go with the three stage because it is a little more versatile. It has the ability to sharpen very dull or damaged knives more easily than the two stage version. In the long run, it will be more useful, at least in my opinion. :)

      Now, if you’re only using this on kitchen knives only, that don’t see any hard action, then, the two stage will do the job.

      The bottom line: the three stage is worth the extra cost.

      Let me know if you have any specific questions. Thanks for stopping by!

    I am a serious home cook, and would like to purchase an electric knife sharpener. The Chef’s Choice 320 sounds like a good fit. Will the Chef’s Choice sharpen Cutco knives?

    Reply
    1. Billy

      Hey Mary! Thanks for stopping by. Yes, the Chef’s Choice 320 will sharpen Cutco knives, and actually, any of the sharpeners on this page will work. I can tell you that the Chef’s Choice M320 or M120 along with the Wusthof will be the better choices. The other thing that I know is that the Cutco knives are not sharpened at a very sharp angle out of the factory — they are probably about 25 degree angles. So the first time you sharpen the Cutco knives, it will probably take a few more minutes at the coarsest stage since you’ll be putting a significantly sharper angle on there. And, it will be worth it!

      The reason I’m mention that is because you might find the 3 stage models more suitable for your application. The “Stage 1″ for both the Chef’s Choice M120 and the Wusthof are coarser and can sharpen dull blades or blades that will be re-profiled faster. The bottom line is that if you can afford to spend the extra dough, go for the M120. You will be able to turn old neglected blades into something that will surprise you with sharpness.

      If you have any follow up questions, let me know. I’m happy to help out!
      Thanks!

      Hi Jim –
      The M120 is at 20 degrees. What kind or style of knives will you be sharpening?

        The main reason for buying and electric sharpener is for my wife for kitchen use but I clean and skin wild game with knives I sharpen on a stone. I like a razor sharp knife but they require constant maintenance. If there is a more efficent way to sharpen my hunting and skinning knives that is as affective as my stone I would be in. That being said do you think I would be satisfied with a 20 degree edge?

          Jim – I understand…
          Yes, I think the 20 degree angle will be fine for you hunting and skinning knives. Do you know what angle you sharpen to currently?

          The only other model I would ask you to check out is the M1520. It can sharpen down to 15 degrees which would be fine for all your knives since you know the sharper angle needs more care. It would most definitely be faster than sharpening by hand.

          Check out a couple videos on the Chef’s Choice Site for the M120 and the M1520.

          If it were me, I would get the M1520. Why not have the slightly sharper angle, right? :) It will only take 30 seconds to touch up the blade.
          Hope that helps! Can I answer anything else?

    Thanks Billy, I don’t know what angle I sharpen to, a man I used to work with was a fierier and a master at working metal, I dont know what you call that but he showed me how to sharpen a knife. I don’t hold a candle to him but I get by. Thanks for the links and advice. I think you might be right on the 1520. I can still sharpen my throwing knives by hand, you don’t want them too sharp you know!

    Chef’s Choice 120 or Wusthof? Which is the better sharpener? There is a Chef’s choice 320 out there…..what is your opinion of that sharpener?

    Reply
    1. Billy

      Hi Gina – I would go for the Chef’s Choice 120 unless you are a huge Wusthof fan. The Wusthof sharpener is actually made by Chef’s Choice and rebranded so the hardware underneath is comparable. And the Chef’s Choice 320 is very nice and even has a 125 Watt motor like the 120 and 130 but it is only 2 stages. If you shop around sometimes you can find the 120 very close to the price of the 320.

      Let me know if you have any other questions. Thanks for stopping by!

    Hi

    We have a large collection of Wusthoff knives that we have purchased over the years. I am going to get a chef’s choice electric sharpener and I have two questions. 1. How do they do with scissors? 2. How long does the grinding material last? 3. How do you replace the grinding material when it is worn down? 4. Does the machine stop when the knife is sharp or do you have to know when to stop running it through the machine? I know some of these questions are probably very basic but I’m new to this type of kitchen device and I want to make sure I understand how they work before I put down the big bucks.

      Hi Ronn –
      Good questions! I’ll do my best to answer each of them and these are great questions for such an investment.

      1. None of the sharpeners on this page will sharpen scissors. If you want a manual sharpener for scissors, then I recommend the Chef’s Choice Pro Scissors Sharpener Diamond Hone. If you want an electric sharpener which is great if you have many pairs of scissors, I recommend the Electric Chef’s Choice 500 Scissor Pro Diamond Hone Scissor Sharpener.

      2. It is a little bit hard to say since it depends on the knives you sharpen and how often you use the sharpener. I know that under normal household use the sharpener grinding discs will last for years. I verified this with Chef’s Choice and they go on to say that, “The abrasives will last for many, many years without need for repair or replacement. If the abrasives need replacement, you may send the sharpener back to EdgeCraft and, for a nominal fee, EdgeCraft will replace the abrasives, clean and lubricate the sharpener and ship it back. The abrasives, however, should last a very long time with normal household use.”

      3. Chef’s Choice will replace the sharpening discs for a nominal fee.

      4. No, the sharpener runs and the discs spin. The user must pull the knife blade through the sharpening stages. It takes a little getting used to, like any new tool. I highly, highly recommend that you practice with some cheaper knives or some knives that you use in the yard or shed. Again, please practice before you pull out your nice collection of Wusthofs!

      Take a couple minutes and check out the video on the M120 and the M1520 here. It should help you see how the Chef’s Choice sharpeners are used.

      Ronn – let me know if you have any other questions or concerns.
      Thanks!

    Hi Billy, thanks for the excellent summary! I am in the market for an electric sharpener – primarily (90% of the time) for Japanese kitchen knives, but also for pocket and hunting knives (10%). After reading this webpage, and the Q&A, I’m leaning toward the Chef’s Choice 320, but concerned that it is only a two-stage sharpener. I do have some dull knives and was thinking that a 3-stage device might be required, but I don’t know for sure. What would you recommend? Thanks much!

    Reply
    1. Billy

      Hey Cal, Thanks a lot for the comment.

      I recommend the M1520 for you. Since you will be using it primarily for Japanese knives, the 15º angle will be great. It is more expensive but I think it’s worth the extra money.

      You can get by with the M320 and only 2 stages but it will take longer to sharpen those dull knives. It’s is not a deal breaker but just something to be aware of.

      As a compromise, the M112, is a three stage sharpener and will serve your needs. It is priced in the middle of the M320 and the M1520.

      I hope that helps and definitely let me know if you have any other questions!
      Thanks again,
      Billy

        Thanks for the quick reply Billy – you’ve convinced me – I just ordered the M1520 and can’t wait to “read the manual” and start sharpening our knives! Thanks again and Happy Thanksgiving!

    Billy, after years of hands sharping my hunting knives I am looking for a quicker and easier means of getting this task done. I have some fairly expensive knifes. So I have a couple of concerns. First, will electric sharpeners hurt my knives? Second, most my knives are small (less than 4 inches, most less than 3 inches) will these sharpens work with this type of blade? And finally I noticed that none of the above sharpens used the flex belt system. Are they not as effective? I sharpen my blades at 20 degrees.

      Hey Gary -
      Thanks for coming by! No, Gary, the electric sharpeners will not hurt your knives. However, they do require a little practice so start with a couple knives that you don’t mind using to learn. It’s just like when you first used a stone for the first few times – it’s a learning process.

      Most of the Chef’s Choice Sharpeners use a 20 degree angle too. The higher end models, like the Chef’s Choice M120 & M130 do have a flexible stropping stage. I think you might be referring to the systems similar to sanding belts – they are just fine. I slightly prefer the Chef’s Choice models. Something like Work Sharp WSKTS Knife and Tool Sharpener would be perfect for a person like you with a background and solid experience sharpening by hand.

      Your main issue would be the small size of the blade. There is only one way to check and that’s to actually have an electric sharpener in front of you. Most kitchen supply stores carry a few models, like Williams Sonoma. They should let you take a look to see how your knives fit in there.

      I hope this helps and let me know if you have any other questions.
      Thanks!
