Top 7 Best Electric Knife Sharpener Reviews in 2019

1. Chef’sChoice 15 Trizor XV EdgeSelect Electric Knife Sharpener

best electric knife sharpener,electric knife sharpener reviews,electric knife sharpener amazon,chefs choice knife sharpener,electric knife sharpener reviews,chef choice electric knife sharpenerThis is set at 15 degrees, and it’s meant for double-bevel or single-bevel 15-degree class knives. You can also use it to convert your 20-degree knives to 15 degrees, so that they cut more effectively and last longer too.

This uses a 3-stage process that doesn’t remove too much metal from your knives, so it can help your knives last longer. The first two stages use diamond abrasives, while the third stage uses a flexible abrasive stropping disk for a smooth and sharp cutting edge.

This third stage stropping disk can also be used to sharpen your serrated knives too. This means you can also use it for your bread knives. You may want to check out the review of the best electric knife sharpener America’s Test Kitchen conducted for this model. It’s so highly regarded that it even topped the knife sharpener category for Cooks Illustrated in 2015.

What We Liked
  • It’s so effective that it can turn damaged knives into seemingly brand new knives.
  • It works very well with expensive knives. It’s like 5 seconds with this gives you similar results to using Japanese wet stones for half an hour.
  • It can sharpen serrated knives too.
  • It’s easy to learn and easy to use.
  • There’s a 3-year warranty.
What We Didn’t Like
  • It’s only for 15-degree knives (or for knives you want to hone to 15 degrees).
  • It’s limited yet it’s so darn expensive.

2. Work Sharp Ken Onion Edition Knife & Tool Sharpener

best electric knife sharpener,electric knife sharpener reviews,electric knife sharpener amazon,work sharp ken onion edition knife sharpener,work sharp ken onion review,work sharp ken onion edition knife sharpener review,work sharp knife sharpener review,work sharp knife sharpenerIf you wish to know how to sharpen electric knife blades and at the same time you’re also looking for the best electric hunting knife sharpener, you may get this and hit two birds with one stone. You can hit a whole flock of metaphorical birds, actually, since this can be used for any type of blade.

This comes with a sharpening angle that you can adjust from 15 to 30 degrees. You just need to turn a knob and you can set the angle in 1-degree increments.

You can use this for yard tools, fishing knives lawn mower blades, axes, machetes, and pen knives. In fact, there’s a built-in scissor guide too at 65 degrees. You just have to make sure that you follow the instructions. Many of those who have had trouble with it were those who just used it on their own.

What We Liked
  • You can use it for just about anything you want to sharpen. There are different belt grits to choose from, and you can upgrade it with optional attachments such as belts for ceramic knives.
  • The resulting sharpness is fantastic. The knife even seems sharper than when it was new.
  • It’s easy to adjust the angle. There’s no need for extra tools or jigs.
  • It’s so good and easy to use that sharpening all your knives and blades seems like fun and not a chore.
  • The belts last for a long while because it keeps exposing new cutting surfaces.
What We Didn’t Like
  • It can get a bit messy with the shavings.
  • You need to wear eye protection. Better yet, a face mask to go with the eye protection may be useful.
  • You have to practice using this with cheap knives to perfect your technique.

3. Chef’sChoice 1520 AngleSelect Diamond Hone Electric Knife Sharpener

best electric knife sharpener,electric knife sharpener reviews,electric knife sharpener amazon,chefs choice diamond hone,chef schoice electric knife sharpener,chef’schoice knife sharpenerNow, this is even more expensive, but at least it’s much more versatile. You can use it to sharpen Asian-style knives at 15 degrees, or you can sharpen Western knives at 20 degrees.

Using this is simple. There’s a dedicated slot for the Asian knives and other slot for the American or European knives (Source). The third slot is for the finishing touches for both types of knives.

Again, that third slot is what you also use if you want to sharpen your serrated knives.

What We Liked
  • It’s easy to use and you get done very quickly. You can finish sharpening about 8 dull knives in half an hour after you read and understand the manual.
  • The instruction manual is also very well written, which isn’t always the case for these things. In some cases, it’s like the manual was written by someone who only has a casual knowledge of English.
  • The results are exceptional, and you really can’t say anything bad about the sharpness.
  • There’s a 3-year warranty.
What We Didn’t Like
  • You can’t really use this for ceramic knives.
  • It’s useless for your scissors too.
  • Not everyone can learn how to use this for serrated knives.

4. Chef’sChoice 120 Diamond Hone EdgeSelect Best Electric Knife Sharpener

best electric knife sharpener,electric knife sharpener reviews,electric knife sharpener amazon,chefs choice knife sharpener,chef schoice electric knife sharpener,chef’schoice 120 diamond hone,chef's choice knife sharpener reviewOnce again we have the familiar Chef’s Choice features. We have the diamond abrasives, the 3-stage process, and there’s a 3-year warranty. This time, though, the knife sharpener designers realized that people may have all kinds of knives aside from just Asian knives and Western-style knives.

This time, you have a knife sharpener that’s good for both gourmet knives and butcher-type knives. This really works with serrated knives, and you can even sharpen hunting knives with this.

What We Liked
  • It’s very easy to use, though you may have to practice a bit at first. After that, it’s virtually idiot-proof according to some owners.
  • It’s a handy tool to touch up your sharpened blades before you use them in the kitchen.
  • It comes with a 3-year warranty.
What We Didn’t Like
  • It’s not really a very good option for your truly expensive knives.
  • You will have to practice a bit before you can use this well. You need to have a cheap knife to practice on first—don’t use your expensive knives for practice!
  • Sometimes the diamond dust particle may be dislodged from the knife sharpener, and you may end up with a minor scratch on your knife.

5. Work Sharp WS3000 Wood Tool Sharpener

best electric knife sharpener,electric knife sharpener reviews,electric knife sharpener amazon,work sharp ws3000 wood tool sharpener,work sharp 3000 knife sharpener,work sharp 3000 knife sharpener reviewYes, it’s quite expensive, isn’t it? But that’s because this electric sharpener isn’t really just for knives. When you take a look at it, you’ll see that there are no slots where you can put your knives and have it sharpened for you.

Instead, you have a spinning wheel against which you touch the blades so you can sharpen them. With this design, you may probably realize that you can sharpen thicker and larger knives. In fact, you can use this to sharpen all your woodworking tools.

That’s basically the main purpose of this sharpener. If you’re a woodworker who needs to maintain the sharpness of your carving tools, lathe tools, plane irons, and chisels, then this is what you need.

What We Liked
  • The sharpening port can handle blades from ⅛ of an inch to 2 inches.
  • You can get consistent sharpness because you already have preset angles from 20 to 35 degrees with 5-degree increments.
  • You can also sharpen larger blades freehand.
  • The purchase includes 16 different abrasives, along with an instructional DVD and a crepe stick for cleaning the abrasives.
What We Didn’t Like
  • There are a lot of accessories, but it doesn’t come with a bag or a case.
  • It takes a longer time to learn and master than you think.
  • Who uses DVDs these days?

6. Presto 08810 Professional Electric Knife Sharpener

best electric knife sharpener,electric knife sharpener reviews,electric knife sharpener amazon,presto 08810 electric knife sharpener,presto electric knife sharpener,presto electric knife sharpener manual,presto electric knife sharpener reviewsYes, it’s cheap, but that not because it’s low quality. The reason is that it’s an old design, though you can argue that it’s a classic design because it works well even now.

With this, you also have a 3-stage sharpening process, though for some the first stage isn’t necessary for knives unless it’s really dull or it has nicks. But that 1st stage is great when you want to use the sharpener for your yard tools.

You’re going to have to practice your sharpening skills with this unit. That means you also need to learn to wipe your blades clean of any metal filings before you proceed to the next stage to keep the blade guides clean.

What We Liked
  • It’s so affordable that at first, we thought it was a manual But no, it’s electric.
  • It’s very effective in providing a sharp edge that even a single pass may do, even if the manual says to do 3 passes.
  • You can use it for yard maintenance tools.
What We Didn’t Like
  • You will have to spend some time learning how to use this properly.
  • The warranty is for a year, but it doesn’t apply to shipping damage.

Taking a Closer Look at on Knife Sharpening

If you’re a beginner when it comes to sharpening your knives, here are some tips that should help you out:

  • Sharpen your knives because it’s safer that way. It’s not actually true that a somewhat dull knife is safer for you because it’s less likely to cut your finger. In fact, it’s more dangerous.

When you have a very sharp knife, you need less force to cut through your food. This lets you more able to control your knife so that it goes exactly where you want it to.

On the other hand, a dull knife requires more force to cut through your ingredients. This means that your fingers are more likely to slip, and the sudden burst of speed may also result in an accidental cut.

  • A sharp knife is also better for the taste of your dishes. It’s been found out that a dull knife actually wrecks the food on a cellular level. The lack of sharpness doesn’t just mar the appearance of your food, but it also causes the taste to deteriorate.

In addition, a dull knife makes food preparation much slower.

  • Use either a manual “pull through” sharpener or an electric knife sharpener. That’s because these systems offer excellent results with minimal effort and in a very short amount of time.

If you value convenience and time-saving, then you may want to forego sharpening stones and steel rods for now. These take a long time to learn properly, and for newbies, they’re just impractical unless you can devote some tome to mastering these things.

  • Make sure the features work for your knives. Some people may also want to sharpen their serrated bread knives, but then some knife sharpeners don’t work on serrated blades, so beware.

Other models are much more versatile, so you can get the best electric knife sharpener for hunting knives if you’re an avid hunter. Other sharpeners can also deal with machetes, pen knives, and even scissors.

  • Sharpen your knives before they get too dull. This minimizes the time and effort it takes to keep the cutting edge sharp. But how long should you wait before you sharpen your knife again?

The answer depends on several factors, including how hard your blade is and how often you use the knife. In general, if a knife is inexpensive or you use it quite often, you also need to sharpen it frequently.

If it’s a cheap knife that you use several times a day, you may need to sharpen the knife every 2 weeks. But a tough high-quality knife that doesn’t lose its edge easily may only need to be sharpened every 3 months or so.

Your best bet here is to note the date when you sharpen the knife, and then note the date when you realize that it has become dull. That should give you a proper time frame so that you can sharpen the knife before it becomes dull.

  • Color the edge of the knife with a sharpie before you start. This will tell you which parts of the edge have been sharpened, and which parts haven’t been sharpened yet.
  • Clean the knife after you sharpen it. This may go without saying, but you mustn’t forget this. You really don’t want to have small bits of metal in your dishes!

Conclusion

So what is the best electric knife sharpener? Obviously, you’re going to your own personal preferences and needs, and what’s best for you may not be suitable for another. However, if you’re looking to sharpen everything in your home that needs to be sharpened, and you want to do it well, easily, and quickly, then you may want to really look at the Work Sharp WSKTS-KO Ken Onion Edition.

This thing works for everything, and it works so well. In fact, it makes sharpening your knives, scissors, lawnmower blades, machetes, and even shovels somehow fun. All you just need to at first is to follow the instructions faithfully, and pretty soon you’ll master it in no time.

You’ll then find yourself searching for other stuff to sharpen, just because it’s so satisfying when you start with dull cutting edges and you end up with razor-sharp knives because of this best electric knife sharpener.
