Best Knife Sharpener – The Best 5 Reviewed – Best Reviews Guru

best knife sharpener

The market today has many different types of knives on offer. Choosing the right one for your needs not be that difficult. What may be more challenging is constantly keeping your knife sharp. The fact is that a sharp knife is not only safer than a dull one but more efficient. It’s less likely to slip off what you are chopping and instead accidentally slice your finger. We would not typically be bothered with knife sharpeners if our knives stayed sharp throughout from the moment we bought them. However, by virtue of what they do, knives do require sharpening frequently.

A sharp knife is a chef’s best mate. Using a blunt knife means you will have to put more pressure on what you are slicing, as a result of which, your soft vegetables or fruits lose their shape or get squashed. It also greatly increases your personal risk of physical injury. Besides the kitchen knives, we have several other types such as survival and hunting knives that are best served when you have one of the best sharpening system sets.

The History of Knife Sharpening

Western style knife-sharpening can be traced directly back to the “Moletas” from Northern Italy. They originated from the Val Rendena valley in Italy`s Dolomite Alps. These knife-grinders traveled from one village to the next offering their knife sharpening services. The first one is thought to have landed in America in 1886 and within 3 decades, he had been joined by hundreds more.

The Moletas had by 1910 become successful enough to acquire their own horse-drawn carts and by the year 1930 they were using trucks to carry their sharpening supplies. Today, according to lansky, although Moletas are still in existence, people have now mastered how to sharpen their knives on their own. Additionally, technology has now reached new levels with modern methods and tools for knife sharpening being widely available today.

Sharpening Stones

For thousands of years, humans have been sharpening blades using stones. The sharpening stone is a rectangular stone block that is ideally about one inch thick and made from different materials such as ceramic, diamond or even natural stones. A sharpening stone is good for dull knives as it removes a lot of blade material, but that tends to age your knife pretty fast.

It is a method that demands some good practice to do it perfectly. This tool was to be found in the majority of homes because it is handy when it comes to sharpening knives, razors, scissors, and other tools. But such days are now a thing of the past.

Manual Knife Sharpeners or Pull-Thru Sharpeners

These are available in different shapes that you can use vertically or horizontally without requiring much physical effort on your part. This tool works best for kitchen knives although you can still use it to sharpen pocket knives. You simply pull the knife through the sharpener to get the knife burrs straightened so as to give a consistent, sharp edge.

Electric Knife Sharpeners

Probably the best knife sharpener in the market today is the electric powered one. Mostly, this is available in the shape of a box that you place at a corner on your kitchen counter. The best knife sharpener typically has one to three slots through which a motorized wheel grinds and spins the edge of your knife to bring a sharp edge.

These types of sharpeners are effective when you want the kitchen knife sharpened fast. However, according to most electric knife sharpener reviews, they could be less effective for tactical knives which demand more control during the sharpening process.

Handheld Sharpeners

Handheld knife sharpeners, similar to electric sharpeners, simplify the process of sharpening. They are, however, generally limited as they have fewer slots to sharpen with. A key benefit of these types of handheld sharpeners is their easy portability. Their manual operating method and small size make them ideal for cooking professionals who travel frequently, such as those engaged in outside catering services.

Depending on the design of the handheld sharpener, you can either draw your knife through the slots while holding the device on a flat surface or draw it along the length of the blade while holding the knife spine-down on the countertop or table. Both types are excellent for easily sharpening a dull knife back to cutting form.

Sharpening/Honing Steels

This is a narrow, long rod made out of ceramic or steel, mostly used in honing a blade. It doesn’t actually shave off too much material. Therefore, it may not be the best tool for sharpening a dull knife. In addition, it needs one to be very careful with the sharpening angle because if due care is not taken, instead of a sharpened knife, you may end up with a deformed blade. These are however the best pocket knife sharpener products for survival and pocket knives.

Dealing with FAQs, notes that sharpening steel is really a bit of a misnomer. The primary job of sharpening steel is honing the knife edge/blade. The four most widely available cuts are diamond, regular, ceramic, and combination.

Knife Sharpener Buying Guide

If you’re investing in a good knife, it makes sense to also invest in a good sharpener. Any knife that is used regularly will eventually become dull and a few moments spent from time to time restoring the blade will indefinitely extend the life of your knife.

The knife sharpening process involves removing a small amount of the material that makes the blade. The less material that gets removed from your knife during the sharpening process, the longer it will last. Take care not to be fooled by all manner of sharpeners that you see being aggressively hawked on Sunday supplements and in discount magazines. Instead, seek expert guidance and ensure that your investment made in a knife doesn’t go to waste.

So what is the best knife sharpener currently available in the market?

Knife Sharpening Systems

Besides the traditional knife sharpeners, today there are numerous knife sharpening systems that are making the work of knife sharpening a walk in the park. Using traditional knife sharpeners like sharpening stones, requires that you have some level of expertise in sharpening knives. Using sharpening systems, on the other hand, is easy as they perform the entire job on your behalf. Some of the systems can sharpen knives with grooved edges, something quite tricky using manual sharpening techniques.

The way people at home sharpen their knives has been revolutionized by knife sharpening systems. Professional chefs are now also using these systems in ensuring that their knives are uniformly sharpened. It’s the perfect for housewives who lack both the time and the needed skills to perform the delicate and at times rigorous task of manual knife sharpening, yet must have sharp kitchen tools.

The different components of the system are stored in plastic holders to ensure they are not damaged or cause harm. In addition, they come with clear guidelines in several languages on how to use them, ensuring maximum safety.

Advantages of Sharpening Systems

The advent of knife sharpening systems has radically changed the entire state of knife sharpening. It is a matchless blend of traditional and modern technology that has greatly contributed to the ease and success of knife sharpening today.

Probably the most notable advantages include the inbuilt safety features, customized settings, multi-stage sharpening system, and the sharpening angle guide. The settings can be tweaked to determine the grit factor according to the knife structure.

With sharpening systems, you are assured of precision, giving your knives a better edge. Some of the systems have replaced the stone with a component containing diamond powder on the surface to facilitate sharpening of ceramic knives. This class of knives cannot be sharpened using a stone as they wear out the stone quite fast, even before they get sharpened at all.

These systems come with inbuilt safety features designed to make sure that you are not accidentally injured as you sharpen your knives. Features of the best sharpening system include safety holders that are finger-grooved ensuring that your hand is not close to the sharpening tools.

Blade Sharpening Angles

Your knife is only good and useful if sharp enough for the task at hand. Knife sharpening angle measurements stand for the angle to which each side of your blade gets sharpened. The smaller the angle between the knife sharpener/stone and the blade, the sharper your knife will be. For kitchen knives, the most common angle is 20-degrees; although, some manufacturers make theirs with a 15-degree angle.

Generally, the greater the blade angle, the more durable and stronger will be your blade, but, remember, you lose sharpness as you increase the angle. For example, according to Knife Sharpeners Buying Guide, sharpening a blade at a 20-degree angle actually, means that it has a 40 degrees total angle.

The best sharpening system comes with several inbuilt settings, the most common being:

Sharpening Angles:

  • These come with different angle settings, each producing different results. If you want your knife sharpened to a razor edge, then a 17-degree angle should be used. A 20 degrees angle is most suited for meat and fillet cutting knives. Any blade angle lower than 20 degrees is normally reserved for sharpening razors.
  • The 18 – 25-degree angles range gives a delicate balance between durability and sharpness that is needed when you are cutting meats, fruits, and cheeses, and vegetables. Boning, carving, and chef knives all generally use angles within the 18-25 range.
  • Hunting knives are good at 25 degrees, as well as other knives used outdoor that need a durable cutting edge, not getting dull too quickly. For knives used for heavy duty tasks like cutting carpets, cardboards, and even wires, 30 degrees is best.
  • The 30 – 35-degree angles range is commonly utilized on cleavers or other types of chopping blades. These normally require considerable force and such large angles provide your blade with the durability and strength necessary to perform the chopping task consistently.

Types of Hones

  • Determined by the grit factor, the type of hones also determines how you will sharpen a knife; higher the grit factor, finer will be the honing.
  • Your hone type should be selected depending on the kind of knife being sharpened; the finer type of hone is best for sharpening blades that are delicate.

It is worth noting that even though certain blade angles and bevels may tend to match up naturally in terms of durability and sharpness, it doesn't mean that they necessarily have to be used together. The points to bear in your mind as you establish the blade angle and bevel type is how you are going to utilize the knife so that you may identify the perfect balance between durability and sharpness.

Protecting Against Blade Damage

The blade of your knife primarily gets damaged by buckling – the compressive force that comes from being pressed into any hard object like bone, or ice – and through bending caused by sideways pressure. Due to malleable nature of metal, both of these actions tend to roll the blade edge.

If your knife is used for scrapping, as a pry-bar, or encounters some hard particles hidden within softer materials, or even a hard cutting board, bending may occur damage. For example, according to Ron Hazelton’ HouseCalls Blog plastic carving board dulls knives faster compared to a wooden one.

Damage may also happen due to acid corrosion (such as cutting tomatoes or lemons) or through exposure to dishwasher corrosive chemicals or high temperatures.

You can avoid blade damage by:

  • Matching an appropriate blade for the task at hand
  • Straight cutting, avoiding side-to-side movement
  • Immediately cleaning the blade after use
  • If appropriate, oiling with food grade oil.


One of the earliest and greatest discoveries made by mankind is the knife. This tool was first used by our ancestors to hunt down animals for meat. During those early times, knife sharpening was crude; it basically entailed rubbing it against a rough stone. Over the passage of time, the knife sharpening technology has witnessed a tremendous evolution. Today, modern knife sharpeners are necessary tools if you want to make your cutting, chopping, and slicing tasks easy.

Whether you are laying out cutlery for a dinner party or cutting up chunks of beef in the kitchen, you need to ensure that the knives perform their tasks perfectly. The knives must have the requisite edge if they are to do the work. Imagine trying to cut a piece of steak using a knife whose edge is only suitable for slicing butter!

A dull knife can really be frustrating. Whether it's a kitchen knife, your fishing knife, hunting knife, or pocket knife, you want a sharp edge that easily gets the task accomplished fast and without too much physical input on your part. That’s why you must get the best knife sharpener that is perfectly suited for your needs, and any of my 5 choices above would make an ideal choice.
