Even the best knife in the world is useless when it’s dull. A quality knife sharpener will help you keep your knives sharp and can actually increase the longevity of your knives.
Whether you’re using knives for hunting, throwing practice, or just in the kitchen, a quality knife sharpener is an essential item to add to your arsenal.
Ever since humans began using knives we had the need to keep these knives sharp. Some of the first sharp-edged tools can be dated back more than 2.5 million years (1). Early knives were fashioned primarily of stone and they were often made for a specific purpose and then discarded immediately after satisfying that purpose.
Today, we fashion knives from a variety of metals and these metals can be routinely sharpened to enhance performance.
We’ve compiled our very own list of the 10 Best Knife Sharpeners to help you find one that’s right for you.

Finding the right knife sharpener depends on your unique needs. Unless you’re experienced with sharpening steel, for example, they can be hard to use safely and effectively, even if you’ve watched Gordon Ramsay’s tutorial a few times over (5).
To guide you towards a sharpener that’ll work for you, our buyer’s guide will focus on these major characteristics: abrasiveness, versatility, mobility, safety features, and price range.
All methods of knife sharpening are ultimately judged on performance. In general, diamond is considered the hardest and fastest sharpening material followed by tungsten carbide and polished ceramic. “Grit” is the term of measurement for a sharpener’s abrasiveness and higher grit means a finer abrasive.
Depending on your experience sharpening knives, you may or may not value an accurate, adjustable angle guide. Many sharpeners with angle guides make it much easier to keep the blade at the correct angle while sharpening. When examining the angle guides offered by a specific sharpener, keep in mind that 15 and 20 degrees are the most common blade angles for kitchen cutlery.
All blades wear differently depending on how much they’re used and what they’re used for. This is why it’s essential to have a sharpener that offers multiple sharpening stages. Coarse abrasives will be used to reshape edges on very dull or damaged knives while finer abrasives work well for touch-ups and polishing.
If you’re primarily sharpening hunting, fishing, or pocket knives, a large cumbersome sharpening system can be difficult to transport. For these purposes, a smaller, lighter, and more compact sharpening system should be used. If you’ll primarily be sharpening kitchen knives, on the other hand, a stationary system is likely suitable.
To put it bluntly: the point of a knife sharpener is to sharpen your knives, not your fingers. You want to make sure you’ll feel comfortable and safe using the sharpening system you eventually decide to buy.
Most manual sharpeners have a built-in safety feature that puts a physical barrier between your fingers and the knife blade. Electric sharpeners tend to be very safe because they utilize slots or rails to guide the knife into the sharpening disks or belt to reduce the possibility of the blade slipping into your hand.
Frequently Asked Questions
In ancient Java, the Kris knife, which was crafted from the stone of a meteorite, was believed to possess magical powers, including the ability to ward off bad luck and protect whoever was wielding the knife (6).
While the right knife sharpener may not give your knife set magical powers, it will help them keep their effectiveness and last longer. Let’s examine some of the most Frequently Asked Questions about knife sharpeners and knife sharpening.
Do knife sharpeners wear out?
The short answer is yes. Sharpeners made from ceramic or diamond steels have a tendency to pick up metal particles as they sharpen. As such, they should frequently be scrubbed with an abrasive cleaner to reduce the likelihood of losing their “teeth.”
How can you tell if your knives need to be sharpened?
Generally, a blade that needs to be sharpened will feel dull to the touch. Blades that can’t cut paper, smash tomatoes, slip off onions, and don’t pass the arm hair test (7) should all be sharpened.
What is the best grit for sharpening knives?
This depends on the stage of sharpening. Generally, lower grits mean a coarser stone. Coarser stones remove a lot of material quickly and are great for repairing chips or setting a new bevel angle on a blade. Higher grits mean a finer stone. Finer stones are best used to polish a blade to a mirror-like finish and hone the cutting edge to razor sharp.
What is the burr of a knife?
Also called a ‘wire edge’, a burr is created when metal is sharpened. The burr will form on the edge of the knife where the planes of the bevels intersect. In the case of one-side knives or chisels, the burr forms where the plane of one face meets the bevel.
Can you use a file to sharpen a knife?
Yes, and this can lead to a very sharp edge, but this technique requires experience. Generally, the use of a small, fine, flat file will help to avoid removing larger amounts of material.
What type of honing oil should you use?
Many sharpening stones should only be used with honing oil. Mineral oil is ideal because it is light and will not harden or turn rancid. Lighter oils are better as heavier oils will actually decrease the stone’s effectiveness. Mineral oil is also safe to work with and doesn’t release and unpleasant odors or harmful fumes.
What is the importance of having a specific angle on a knife blade?
Fine angled blades tend to be more effective in slicing and delicate knife work, but they will become dull more quickly. Wider angled blades tend to hold up better for rough chopping and other, more intense uses.
Can a knife sharpener damage my knives?
All sharpeners are safe for the specific types of knives they’ve been designed to sharpen. However, you should be careful to read and understand directions thoroughly before sharpening. Improper use of a sharpener, such as applying too much pressure, could result in damage to the blade of your knife.
