Best Electric Knife Sharpener

We tested the Chef’s Choice 15XV sharpener on a variety of kitchen knives and came away impressed. The three-stage sharpening process really does produce an ultra-sharp edge. We started with some dull chef’s knives and after just a minute or two, they were slicing through tomatoes like butter.

The 100% diamond abrasives work quickly to reshape and refine the blade edge. We like that it can handle both straight and serrated knives. The precision angle guides take the guesswork out of getting the right sharpening angle.

This unit is on the larger side, so you’ll need some counter space to use and store it. It’s also fairly noisy when running. But for the results it delivers, we think it’s worth it for serious home cooks who want to keep their knives in top shape. The ability to convert 20-degree edges to high-performance 15-degree edges is a nice bonus too.

We tested the Presto EverSharp Pro and found it to be a solid choice for home cooks looking to keep their knives sharp. The 3-stage system made it easy to get a good edge on our dull blades. We liked how it handled different knife types, from chef’s knives to smaller paring knives.

The adjustable blade guides were helpful. We could set them for thick hunting knives or thin fillet knives. This feature gave us more control over the sharpening angle. The suction cup feet kept the unit steady on our countertop while we worked.

One thing to note is the noise level. It’s pretty loud when running, which might be an issue in small kitchens or shared spaces. We also noticed it can be a bit aggressive on softer steel, so it’s best to start with light pressure. It took us a few tries to get the hang of it, but once we did, we got good results. For the price, we think it’s a solid option for most home cooks who want sharp knives without the hassle of manual sharpening.

We tested the Presto EverSharp on a variety of dull kitchen knives and were impressed with the results. The two-stage system made quick work of restoring sharp edges. We liked how the blade guides held each knife at the right angle, taking the guesswork out of sharpening.

The Sapphirite grinding wheels did a nice job on both cheaper and higher-end knives. We noticed a big improvement in cutting performance after just a few passes through each stage. It was satisfying to slice through tomatoes and herbs with ease after sharpening.

One thing to keep in mind is that this sharpener can be a bit aggressive. It’s best to use a light touch and not overdo it, or you might remove more metal than needed. The process is also pretty loud, so it’s not ideal for quiet kitchens. Still, for the price and ease of use, we think the Presto EverSharp is a solid pick for most home cooks who want to keep their knives in good shape.

We tested the Chef’s Choice Trizor XV in our kitchen for several weeks. The three-stage process was simple to follow. We just pulled our knives through each slot a few times. Our dull chef’s knife became razor-sharp after about a minute.

The 15-degree edge it creates is noticeably sharper than the standard 20-degree edge on most knives. We found our newly sharpened knives cut through tomatoes and onions with less pressure. The edge also seemed to last longer before needing resharpening.

One downside is that it removes more metal than some other methods. But for most home cooks who sharpen their knives a few times a year, this isn’t a big issue. We think the Trizor XV offers a good balance of ease of use and sharpening performance for its price. It’s a solid choice if you want to keep your knives very sharp without learning manual sharpening skills.

When we tried out the Narcissus Electric Knife Sharpener, we were impressed by how fast it brought our old kitchen knives back to life. The two-stage system made quick work of even our most worn-out blades. We started with the coarse slot to reshape the edge, then moved to the fine slot for polishing.

The sharpener felt stable on our countertop, and we liked that it didn’t slide around during use. Its stainless steel body looks nice enough to leave out, which is handy for frequent sharpening. We found the magnetic dust box at the bottom helpful for keeping our workspace clean.

Using this sharpener does take some practice. We had to pay attention to the angle as we pulled knives through, but once we got the hang of it, the results were great. Our knives cut through tomatoes and paper with ease after sharpening. While it’s a bit loud, we think it’s a fair trade-off for the convenience and speed it offers compared to manual sharpeners.

When we tried out the Homly sharpener, we were happy with how quick and easy it was to use. The three stages let us sharpen dull knives and put a nice polish on blades that just needed touching up. We liked that it worked on most of our kitchen knives, from chef’s knives to smaller paring knives.

The diamond abrasives did a good job of putting a new edge on our blades. We found the spring-loaded guides helpful for keeping the right angle as we pulled knives through. This made it simple to get good results without much skill or practice.

One thing to note is that this sharpener is pretty noisy when running. It also tends to remove more metal than hand sharpening, so we wouldn’t use it on our best knives. For most home cooks looking to keep their everyday knives sharp, though, we think it’s a handy tool that gets the job done fast.

We tried out the Northmas Electric Knife Sharpener in our kitchen, and it impressed us with its speed and ease of use. The two-stage sharpening system worked well to bring our dull knives back to life. We liked how the first stage quickly sharpened the blade, while the second stage gave it a nice, smooth polish.

Using this sharpener was pretty straightforward. We just had to place the knife in the slot and pull it through a few times. It took us about 30 seconds to sharpen each knife, which was much faster than using a manual sharpener. The compact size was a plus too – it didn’t take up much space on our countertop.

One thing to note is that it took us a bit of practice to get the right angle when pulling the knife through. Also, while it worked great on our straight-edge knives, it’s not made for serrated blades. The plastic body felt a bit less sturdy than some other sharpeners we’ve used, but it got the job done. For home cooks who want a quick way to keep their knives sharp, this Northmas sharpener could be a good fit.

We found the VIDOME electric knife sharpener to be a solid choice for home cooks. Its 3-stage system with diamond abrasives quickly restored our dull knives to razor-sharp condition. The first two stages sharpen and hone the edge, while the third stage polishes it to a smooth finish.

Using this sharpener was straightforward. We liked the safety guides that held our blades at the right angle. It took about 30 seconds for the first sharpening and only 10 seconds for touch-ups. The machine worked well on both metal and ceramic knives, which is a big plus.

One thing to note is the noise level. At 60-80 dB, it’s not the quietest option out there. We also had to be careful not to over-sharpen, as it’s easy to get carried away with such an effective tool. Still, for its price and performance, we think this VIDOME sharpener is a good buy for most kitchens.

The Work Sharp MK2 impressed us with its versatility. We sharpened kitchen knives, pocket knives, and even garden tools with ease. The flexible belts did a good job following the curves of different blades.

We liked the two-speed motor. The low speed worked well for touch-ups, while high speed quickly restored very dull edges. The edge guide helped us keep a steady angle, though it took some practice to get consistent results.

One thing to note – this sharpener can remove metal faster than manual methods. We had to be careful not to over-sharpen. The belts also wear out over time and need replacing. But for the performance and ease of use, we think it’s a fair trade-off for most users.

We tested this Chef’s Choice sharpener on a variety of dull kitchen knives. The results impressed us. In just a few minutes, it brought our old, worn-out blades back to life. The diamond abrasives in the first stage worked quickly to reshape the edge.

The three-stage design lets you choose how fine you want the edge. We liked using stage two for a micro-serrated finish on our chef’s knife. It gave us great bite for slicing tomatoes. For a super smooth edge on our paring knife, we finished with stage three.

One thing we really appreciated was how easy it is to use. The angle guides took all the guesswork out of sharpening. We didn’t have to worry about holding the blade at the right angle. The motor isn’t too loud, and the rubber feet kept it stable on the counter. While it’s bigger than a manual pull-through sharpener, we think the results are worth the extra space.
