10 Best Knife Sharpeners In 2021

The KitchenIQ 2-Stage Sharpener is a small tool that, at under an ounce, is easy to keep in your kitchen even if your home or apartment’s kitchen is small. You can even choose between black, green, or red, so you can pick something that matches your taste and decor.

The ergonomic grip makes it easy to hold it in place while the non-slip base adds stability and protects you from the safety issues of a sliding sharpener. It also uses Kitchen IQ’s patented Edge Grip feature. This feature makes sure that the tip of the large knife you’re sharpening doesn’t scrape across and damage your counters.

The two slots on this sharpener are labeled “fine” and “coarse”. The “coarse” slot houses carbide blades that are meant to sharpen your dull kitchen knives. The “fine” slot uses ceramic rods that are made to polish up that sharp edge to hone it for an effective finish.

KitchenIQ suggests that you run your knives through this sharpener before every use to keep them in top condition and to extend their lifespan, so you won’t have to replace your kitchen knife set anytime soon. It’s an easy step to add to your food prep process since it only takes a few runs through the slots to get your knives back on top.

Electric sharpeners make your job easier by doing most of the work for you and the Presto EverSharp Electric Sharpener lives up to that promise. The sharpener uses a professional-grade, two-stage process to sharpen your knives. The first step works to create the angled edge you need while the second stage hones that angle into a sharp edge. While there are two steps, you’ll notice that there are two slots on either side of the sharpener. This is because each of the slots in a single-stage caters to a different angle of the blade. Not only does this make it easy for users to sharpen their knives at the right angle, but the sharpener automatically guides the blade along, so it’s sharpened at the right speed as well.

The sharpener uses Sapphirite sharpening wheels to give you the razor-sharp edge it offers. While this isn’t as common in household electric knife sharpeners as materials like ceramic, it is a material found in plenty of professional and industrial electric knife sharpeners and it holds up well over time. The electric nature of this model also makes sharpening your knife a quick and easy process. Once you turn it on, you can have a sharp knife ready for precision cutting in under a minute.

The SunrisePro Supreme Sharpener is made to help keep every knife in your kitchen as sharp as possible from steak knives to paring knives to butcher knives. You can even use it for your pocket knife but it isn’t made for scissors or serrated blades.

It’s also made for anyone to use. While it is a manual sharpener, you aren’t going to have to worry about intricacies like holding your knife at the right angle. The tungsten carbide sharpening blades in this model are positioned at a 20-degree angle. This means that you can hold your knife at a 90-degree angle to the sharpening blades and pull your knife straight back. SunrisePro also instructs that you only need to run your knife through the sharpening blades three times which makes sure your knife is ready to go in seconds.

Safety is also a big focus of this sharpener. While many sharpeners provide safety with a non-stick bottom, SunrisePro takes it a step further with a suction cup base that temporarily but securely seals to your counter during use. This also means you don’t have to hold the sharpener in place with your other hand while you run your knife through it.

Perfect for kitchen knives, the compact design of the AccuSharp Sharpener also lends itself well to travel and outdoor adventure. It’s built to be handheld and is easy to carry with you either in your pocket, in your pack, or even just stored in a kitchen drawer. If you want to use this sharpener in both your kitchen and on your next camping trip, you don’t have to remember to switch the location of the sharpener back and forth because you can order it as a single device or in a bundle of three.

The slot for sharpening your knife is small to help keep the device as a whole small and a plastic cover around the handle protects your hand from the blade of what you're sharpening while you use it. This design is also handy because it accommodates you whether you’re right-handed or left-handed. The sharpening blades are made of diamond-honed tungsten carbide blades and the sharpener also uses diamond-coated rods. This sharpens your knives, no matter if they’re serrated or smooth, in about three to four strokes. All you need to do is glide the sharpener down the blade, letting it get into every groove in the case of serrated blades.

The Lansky Deluxe Sharpener is a five-stone system that comes in a set that gives you all the resources you need to sharpen your knives properly. This includes the five hones as well as a multi-angle clamp, guide rods for every phone, and the honing oil you need to lubricate the hones. These hoes include an extra-coarse 70-grit hone, a coarse 120-grit hone, a medium 280-grit hone, a fine 600-grit hone, and an ultra-fine 1,000-grit hone. Each of these stones is color-coded for an easy organization as black, red, green, blue, and yellow respective to the grits just discussed.

To use these hoes, you’re going to put your blade in the clamp and thread the hone through one of the holes on the clamp depending on the bevel angle you want. These angles include 17, 20, 25, and 30 degrees. Low angles of 17 degrees are best for your sharpest blades like razors and fillet knives. Higher angles of 30 degrees work better for heavy-duty use such as blades that are made to cut rope or carpets.

The included instructions will help you learn exactly how to use these hones and the equipment with them to make sure your blades are sharpened properly. This versatility helps you take care of every blade you own.

The LINKYO Electric Sharpener is a 2.7 lb electric sharpener that’s made to be a staple on your kitchen counter. It’s another option that uses two-stage sharpening with the first stage reshaping your blade back to the edge it should have while the second stage hones and polishes that edge. Since it’s an electric model, it guides you through the whole process. All you have to do is put your knife in the slot and slowly pull the knife back towards you. You don’t need to worry about applying any downward pressure. The sharpener has a “stop” feature. This activates and stops the machine if too much downward pressure is applied. This protects both the machine and your knife from damage.

These slots are also slanted with two slots per stage. This makes sure that you don’t have to worry about holding your knife at the right angle to sharpen it properly. Each of these slots also caters to a side of your knife so that the blade comes to a perfectly sharp point.

For safety and ease of use, this sharpener is designed to stay firmly in place. The suction cup feet on the bottom of the sharpener help it stick to your counter while you use it and don’t require you to put your other hand near the blade to hold the sharpener in place.

The Spyderco Tri-Angle Sharpener is a whetstone-style sharpener that puts a large focus on giving you the freedom to work at the angle you need for the blade you’re working with. It does this by giving you an ABS plastic base with keyed holes.

All you have to do is set the sharpening stones into the keyed holes at the angle you need them at with the set options being a 30-degree sharpening angle or a 40-degree sharpening angle. This refers to the angle on each side. So, for example, if you have a knife with a 15-degree bevel angle, you’ll want to set the stones up so that they’re in the 30-degree positions. The kit also comes with brass safety rods to sit in the plastic base to protect your hands while you sharpen the blade.

As far as the sharpening stones themselves, you have two pairs of alumina ceramic stones to use. The brownstones have a medium grit made for sharpening dull blades while the white stones are finer and are made to give your knife a professional finish once it's been sharpened on the coarser stone. Once you’re done sharpening your knives up, the plastic base, brass rods, and sharpening stones fit easily together to allow for easy storage.
