Features of the Best Knife Sharpeners in 2021

Types of Knife Sharpeners:

Pull Through Knife Sharpeners:

This refers to sharpeners that require you to place the blade in a specific slot and then pull the blade back to sharpen it. There are two types of sharpeners available.

Electric Pull Through:

Works by pulling the blade and sharpening it with a revolving grinding stone mounted on a motor with slots. They’re a little pricey, but they’re great for workshop knives.

Manual Pull Through:

This sort has no engine, so you’ll have to manually position the blade and pull it to sharpness. The majority of the sharpeners listed in the article are pull-through manual sharpeners. They’re not as expensive as an electric sharpener, but they’re great for sharpening kitchen knives.

Stone sharpeners:

Sharpening was once common among the older generations, and butchers and professional chefs still use it today. It is actually a stone on which the knife blade is positioned at a certain angle and then ground to make it sharp. There are two kinds of them this time.

  • Oilstones are made of Aluminum Oxide or Silicon Carbide that has been coated with oil. They’re typically inexpensive and the go-to choice.
  • Waterstones are commonly found in India and are known for sharpening quickly. They, too, are available in both natural and synthetic forms.

Honing/ Sharpening Rods:

A honing rod is the most common method of sharpening a knife, and it has become increasingly popular as a result of its repeated presence on television. It’s nothing more than a solid metallic/ceramic rod attached to a handle (usually made of fiber or plastic).

This is the same Rena Germany rod listed in the list. Professional cooks, as well as culinary hobbyists, also use honing rods. They are, however, an excellent match for a modular kitchen knife package.

Knife Sharpening Kits:

Knife sharpening kits, which are similar to honing rods, are a new public sensation. Oilstones, Waterstones, and a honing rod are among the small tools used to sharpen a blade to perfection in a traditional knife sharpening kit. Electric knife sharpening kits are also available.

The angle of sharpening:

You can’t just put the knife’s blade down, push or pull it, and expect it to be sharp. To sharpen the blade, it must be positioned at a specific angle. The motors in electric knife sharpeners have slots for a few different angles.

Manual sharpeners, on the other hand, have pre-set angles in their slots that are thought to be suitable for sharpening. Sharpening rods and grinding stones, on the other hand, are devoid of all such angles.

Develop a V shape with the rob/stone by placing the blade at (usually 20-22 degrees for German knives and 15 degrees for Japanese knives).


There is always grit, regardless of the type of knife sharpener. In simple terms, the grit amount is defined by how much metal is extracted during the sharpening process.

To put this in perspective, a medium grit (1000-3000 grit) is used to sharpen dull knives that aren’t broken, while fine grit (4000-8000) is used to refine the knife’s edge and is equivalent to honing steel.


This is typically the case for food on view. Food products cut with a blunt knife would certainly seem unappealing and filthy. Foods cut with sharp knives would undoubtedly seem appealing and appealing to the eyes. Always make an effort to use sharp knives.


Almost all knife sharpeners can complete the mission, but some can do it much faster than others. We don’t think you would mind wasting 5 minutes per knife running it up and down a whetstone as a skilled chef.

If that doesn’t sound like fun, look for a sharpener that just takes a few passes through it. They’ll complete the same mission in a fraction of the time.


Some knife sharpeners are designed to be robust, minimizing the risk of slipping and injury when in use. Most have suction cups that stick to the work surface to keep it in place as you work, but you must still hold the machine down while working because it can still move even though it appears to be stuck to the worktop.

Nobody wants to lose control when attempting to achieve razor-sharp knifepoint. There are a few that can be attached to a surface and a few that have locking suction cups.

If you’re worried about the machine’s stability, take a look at any videos the manufacturer has released in an advertisement or if someone has done a thorough analysis of the device.

User Friendliness:

Many people find knife sharpening to be a frightening task, which has resulted in the growth of a large knife sharpening service industry. The home chef, on the other hand, is unlikely to want to pay for skilled service, and genuinely devoted chefs are unlikely to want someone else near their knives in the first place.

The trick to keeping your knives sharp is to have a knife sharpener that is simple enough to use on a regular basis. Pull-through style manual sharpeners, for example, make up the majority of our list, most likely because they were created with the goal of making the process easier.

These products were able to reassure cooks all over the world that holding a properly sharpened knife is simpler than it looks by fixing a set of grinding wheels in safe slots and offering specific instructions for use.


It goes without saying that safety is paramount. When you’re looking for a manual or electric knife sharpener, check to see if there are any extra safety features or if there are any alerts that you should be aware of.

Some handheld models may come with a finger guard, and some manufacturers may suggest (and ideally provide) a protective glove or mask to use with your new tool.  Metal shards and dust will be generated by an electric knife sharpener, a manual knife sharpener, and a whetstone.

You can prefer to use the tool outside before you become accustomed to the amount of metal dust produced. To prevent damage, always clean the sharpener according to the manufacturer’s instructions, scrub the freshly handled knife with a damp cloth before using it, and keep concentrated when using such tools.

Available Price:

Knife sharpeners will cost anywhere between $10 and $150. Consider your budget and purchase the sharpener with the highest ranking in your price range. If you intend to use the sharpener on a weekly or monthly basis, a higher-end model that is built to last is a good choice.

If you’re just using it to keep your knives in tip-top shape before the holidays to carve your Thanksgiving turkey or Christmas turkey, you probably don’t need a super-expensive model.

FAQs for the Best Knife Sharpeners in 2021

Knife Sharpeners: Are They Dangerous to Knives?

No, knife sharpeners are not evil and will not damage your knife if you make sure the knife sharpener you're using is absolutely acceptable for the blade you want to sharpen. Knife sharpeners, when used correctly, can significantly minimize knife damage and drastically prolong their life.

Is it possible to use a knife sharpener on any kind of knife?

Yes and no. If the knife sharpener has different slots and stages with different sharpening materials, you can use it to sharpen any kind of knife you have in your kitchen. However, this is not possible, particularly with serrated blade knives, as these blades are not the same as plain edge blade knives.

How can you sharpen knives with a knife sharpener?

Simply position the knife's heel in the groove and pull gently from heel to tip to use a hand-held knife sharpener. It's best to use a firm, steady stroke and avoid pressing down too hard, as this might damage the blade.

Repeat five to fifteen times until the knife is razor-sharp. Some sharpeners have several grooves for honing and polishing the blade, so you may need to use more than one.

Which knife sharpener is more powerful: a diamond or a ceramic knife sharpener?

Diamond is widely regarded as the best tool for making knife sharpeners because it can cut through even the toughest metals. Sharpening steels with diamond coatings work efficiently and create a sharper blade in less time than ceramic steels.

They do, however, remove a significant amount of steel from the blade. As a result, if you sharpen your knives on a regular basis, it's safer to go with a ceramic knife sharpener.

Is it possible to use a countertop knife sharpener to sharpen knives?

Countertop knife sharpeners are table/platform mounted pull-through sharpeners. They are set in place and do not move about, making it easy for you to pull them. Sharpeners without angled edges are not recommended for sharpening blunt knives.

Even, if you have an expensive or high-quality knife, stop using a countertop knife sharpener. It's likely that you'll end up destroying the blade rather than fixing it. They are, however, perfect for quickly removing knicks from your knife before cutting anything.
