The best knife sharpening system for you depends on how willing you are to invest time into the job and how good an edge you’re willing to work for.

For an electric knife sharpener that is adjustable and capable of honing not only your knives but all kinds of cutting tools, the Work Sharp Ken Onion Edition is a great choice.

  • Sharpens blades to a convex edge for improved performance
  • Variable speed motor for slow speed honing of high-speed grinding
  • Uses replaceable abrasive grit belts—comes with extra-coarse (P120), medium abrasive (X65), fine abrasive (X4), extra-fine abrasive (6000)

  • Suitable for sharpening a wide range of cutting tools
  • One-year warranty

No matter what type of knife you want to sharpen, the Work Sharp can be adjusted to suit your needs. That’s what sets this tool apart from the standard kitchen knife electric sharpener. It’s also capable of working serrated and odd-shaped blades, which the average sharpener can’t do.


  • Adjustable angle guide and motor speed
  • Easy to set up and use
  • Quickly hones blades of all types


  • The guide can make it difficult to sharpen near the heel of the blade as the handle gets in the way, and the tips of blades may slide off guide as they become narrower
  • Grinding belts wear out comparatively quickly if used a lot, which can be expensive to keep replacing

The Ken Onion edition of the Work Sharp knife sharpener has several improvements over the original Work Sharp tool, which makes it more versatile. From the adjustable guide to the multi-speed motor and the extra grinding belt, this makes a great tool.

Buy it if you want some extra freedom in your sharpening capability, while still retaining useful guides and plenty of power to speed up the job.

12. Best Knife Sharpener in the World: Lansky 4-Rod Turn Box LCD5D

Lansky 4-Rod Turn Box LCD5D

There is no “best” knife sharpener in the world because there are far too many different designs and intended uses. That being said, for a portable easy-to-use sharpener designed for those who already look after their knives, the Lansky 4-Rod Turn Box is a very good contender.

  • Hardwood base/container
  • Rods stored inside base for convenience and protection
  • Small and lightweight
  • Two pre-set sharpening angles (20 and 25⁰)
  • One-year warranty for materials and workmanship

The Lansky helps users gauge the pre-set angle at which to sharpen their blades. Being a vertical setup, this is easier to follow by eye than the standard horizontal sharpening stone.

It still gives the user free rein if they have blades that require sharpening at a different angle, so this is more versatile than the standard pre-set style.


  • Simple and effective to use
  • Compact and good protection for ceramic rods
  • Two grades of abrasive
  • Pre-set rod angles help guide sharpening angle
  • Replacement rods of various grades are available


  • Takes practice to use correctly

  • Rods work best with regular cleaning

Because it can easily be stored inside itself, making a compact and lightweight unit, the Lansky is great for carrying around with you or storing in a kitchen drawer. It’s much lighter-weight than standard sharpening stones.

Rods are easily replaced if lost or broken, and different grit grades are available, which could turn the tool into a four-grit sharpening system if desired.

Buy it if you want a handy, multi-function sharpener that’s easier to use than some systems and will easily look after blades that are kept in decent condition.



Knife Sharpener Types and Suitability

hand sharpening knife with electric sharpener

There are myriad types of knife sharpeners on the market, and each is best suited to particular uses and requirements. The broad types are outlined below.



hand sharpening knife on a Whetstone

Whetstones are the oldest form of sharpening tools. In ancient times, these would’ve been as simple as a suitable rock. Some traditional whetstones still use stone as a material for certain applications, but most modern whetstones are formed from a range of abrasive compounds.

Many grades of abrasiveness are available for whetstones, from very coarse (which removes a lot of material quickly but leaves a rough edge) through to very fine (which removes minimal material and gives a fine, polished edge).

Starting with a dull or damaged blade, a coarse whetstone is first used to clean up the edge and get the angle right, before progressively moving through finer grades to bring the edge to a finely polished finish.

Natural stones require water as a lubricant to help wash away removed material. Man-made compounds can be used with either water or honing oil.

Oil slows the sharpening process as the lubricating effect removes less material, but it helps give a smooth finish.

knife sharpened with oiled whetstone

Most stones will work with water, but it’s important to note that once oil is applied, the porous nature of the stone is altered and water will no longer work.

Whetstones are best used when securely held on a bench or table so that the knife can be drawn across their surface. This ensures good consistency and allows the user to guide the knife with both hands.

The blade should be held at the correct angle to the stone and drawn across the length of the surface, edge first. The sweeping stroke should start at the heel of the blade and fade out to the tip by the end of the stroke to ensure an even grind along the length of the blade.

Small pocket stones are handy for carrying in the field. These are usually operated in the hand, so care must be taken. Rather than long sweeps along the stone, circular scrubbing motions are easier to perform on the short surface.


Sharpening/Honing Steels

knife and sharpening steel on cutting board

Steels should be the final step in any sharpening process. The main purpose of these is to polish the blade.

However, some sharpening steels, like a diamond steel, do remove material and sharpen the blade to a degree. These can be considered to be a moderately fine grit application.

Honing steels are a steel rod with fine (or no) grooves along their length which help to form the shape of the edge angle.

They should be used on a regular basis to keep the blade in good shape and reduce the need for abrasive sharpening.

The less pressure applied while running the blade along the steel, the finer polish.


Pre-Set Sharpeners

knife honed with Jiffy-Pro Handheld Sharpener

Pre-set sharpeners come from pocket-sized tools to bench-mounted machines that precisely hold blades in place while the sharpener runs over them.

The quality of tools, and the resultant quality of the edge achieved, also varies greatly.

For a quick-and-dirty job, the little hand-held pre-set sharpeners are adequate. They use some kind of abrasive surfaces inside a groove that the blade is slid through. The abrasives are positioned at a defined angle to concurrently grind each side of the blade edge as it’s drawn through.

They can be a bit fiddly to use as both the sharpener and the knife need to be held steady. Larger versions that have a flat base can be better held on a solid surface.

It’s important to draw the knife through with no downwards pressure. Forcing the blade through only chews through it and will wear the knife out quickly.

Precision pre-set sharpeners usually provide a way of clamping the blade in place, and the sharpener is drawn over the blade. The best ones have the sharpener attached on a slide so that all movement is precise and easily repeatable. Those that allow for adjustment of sharpening angles are the most versatile.


Electric Draw-Through Sharpeners

Electric draw-through sharpeners include the standard kitchen sharpening appliances. These work on a similar principle to a standard pre-set sharpener in that the blade is drawn through a groove that houses the abrasive surfaces and aligns it at the correct angle.

Instead of a fixed abrasive surface, however, electric sharpeners have spinning grinding wheels that quickly grind the blade to the desired angle.

The better machines have multiple grooves with abrasives of different coarseness so that a finer polish can be achieved.


Bench Grinders

Bench grinders are heavy-duty machines best suited to those who need to frequently sharpen knives and other cutting tools.

They consist of a revolving whetstone that runs at a relatively slow speed. This method can quickly sharpen a blade as compared to the standard whetstone, but doesn’t generate enough friction to destroy the temper of a blade.

A bench grinder specifically designed for sharpening knives should have some sort of guide to aid in maintaining the correct blade angle.

Alternatives to this design are similar machines that are hand-held, like the Work Sharp Knife and Tool Sharpener included in the above recommendations.

Buying Advice: What Type of Sharpening System Is Right For You?

knife set held out in the woods

Before buying any sort of knife sharpening system, it’s best to decide how much effort you’re willing to devote to maintaining your knives and what sort of quality of blade you deem important.

If you will settle for nothing less than shaving-sharp knives, and are happy to invest some time and effort towards learning how to use manual sharpeners, then that kind of system will be appropriate.

On the other hand, if you just want a blade that will cut with the minimum of fuss, then perhaps an electric sharpener or some kind of pre-set draw-through tool will suffice.

There’s nothing wrong with using a combination of tools. A pre-set tool can quickly remove damage and set the blade angle before a gentle clean-up with a whetstone and honing steel finishes the job.

Simply put, the quicker the machine works, the rougher the final result will be.


Pre-Set Sharpeners

man sharpening knife with Presto Eversharp

In terms of electric and pre-set sharpeners, look for models that fix or rest securely on a solid surface (unless you want one to carry around in the field). Having a solid foundation is the first step towards consistency.

The better models will have precise blade angle settings that can be adjusted and guides that ensure the blade stays positioned consistently.


Manual Systems

different kinds of whetstones

As for manual sharpening systems like whetstones, a man-made compound provides a consistent product with plenty of variation at an affordable cost. They don’t last as long as natural stone, but their price makes them disposable tools.

Check whether the stone is designed to be used with oil or water as a lubricant – or will work with either.

Oil stones give a smoother finish but take longer to sharpen a blade, and you need to have oil on hand.

Water stones work faster but wear out faster as well.

Importantly, once a stone has been used with oil, it’ll no longer work with water due to the change in porosity, so using oil is a one-way street.

Like knives, sharpening and honing steels are dependent on the quality of steel and craftsmanship. For this reason, buy only quality butcher and chef brands such as Victorinox, F. Dick, and others. Steels are expensive but you’ll have to work hard to wear one out.


Serrated Blades

If you own serrated blades, or knives with oddly-shaped cutting edges (like gut hooks), it’s a good idea to invest in some sharpening rods. Think of a serrated blade like a chainsaw – you need a chainsaw (rat-tail) file to keep it cutting.

Each tooth of a serrated blade needs to be sharpened, and to do that, you need a rod of the same diameter as the inter-tooth width.

Generally speaking, because a serrated blade cuts like a saw – with each tooth performing a small cut by “ripping” rather than slicing – you’re best off having a slightly rougher edge, so you don’t need to go super-fine in the abrasive grit of the rod.

Gut hooks, on the other hand, are made to slice and have a very limited surface area, so you’ll want to get the finest hone you can to make things easier.


Best Sharpener Brands

When it comes to sharpeners, look for quality brands with a good reputation. Knife sharpening is a precision task, and therefore spending money for a quality product will leave you with a better experience at the end of the day.

Work Sharp

Work Sharp logo

The Work Sharp brand is part of the DAREX family, manufacturers of sharpening tools for several uses since 1973. The company is based in Oregon.

They keep their focus on specialized sharpening tools and generally get it right. All of their products are backed with good product warranty and customer support.

The Work Sharp line of products produces sharpening tools for the home/workshop as well as to be carried in the field. All products are versatile and dependable, without having so many gadgets that they miss the point of what they were designed for.

These are tools designed to work, and they can be trusted to keep your knives and other tools in top condition.


Edge Pro

Edge Pro logo

Ben Dale made a living out of sharpening knives. Through this total immersion in the craft, he designed his own tools to make the job more consistent and quicker, and the Edge Pro sharpening system was the result.

Many pre-set sharpening tools are basic and a bit rough on gear – not so with Edge Pro. Relying on the machines to make one’s livelihood is justification enough for this brand to make the list of top products.

These tools are made to be portable – a great asset – and can be used anywhere. They also include comprehensive instructions so that you really can’t go wrong.

They also come with a lifetime warranty for the sharpening systems, excluding those parts that wear out (which is just part of using abrasives).

This is a tool that anyone who is serious about sharpening will appreciate having around. In this instance, the investment will pay off.

EdgeCraft’s introduction of the Chef’sChoice electric sharpener in 1985 changed the way knife sharpening was done, and its Chef’sChoice® Diamond Hone® Sharpener Model 100 was the first advanced electric knife sharpener in production.

The brand has branched into many kitchen appliances, but its knife sharpening tools – electric and manual – remain one of its main business lines. Based in Avondale, PA, these handy tools are still in high demand.

From the everyday kitchen to commercial restaurants and other areas of the food industry, Chef’sChoice has cemented its place as a reliable maker of knife sharpening equipment.

Can a knife sharpener be used for scissors?

Certain types of sharpeners can be used on scissors, but a set of scissors is different from a single knife blade. They are technically a set of shears, and the blades cut by the two sharp edges sliding past each other at a very close, precise angle.

Because of this, you only ever sharpen the beveled edge of a set of scissors. Do not sharpen the faces that slide past each other, as you’ll open up the gap and ruin the scissors.

Most pre-set sharpeners will not work for scissors as their angle won’t fit the angle of the scissors. Even if a sharpener states that it can sharpen scissors, check that the angle corresponds to that of the scissor blades before starting.

It’s best to sharpen scissors on a wide, flat abrasive surface. Take your time to get the angle right and lightly work until you’ve polished the blade.


How does a knife sharpener work?

Knife sharpeners work by removing material from a blade at a certain angle until that angle fades off the blade edge. When this is fully achieved, the blade edge will be at the finest thickness possible – which is a sharp edge.

Coarse abrasives take material off a blade quickly, so they’re best used to work with blunt and/or damaged blades. Due to the coarseness – the size of the grit – in the abrasive, the final edge won’t be very smooth.

By using increasingly fine abrasive surfaces, the blade edge becomes smoother and smoother until it looks perfectly flat to the naked eye.

The finest abrasive we can use is a taut leather strop, which the blade is lightly drawn across. As you can imagine, this will only remove microscopic metal particles, but this does make the blade that much smoother.


What knife sharpeners do chefs use?

Chefs use a variety of tools to sharpen blades. Some use high-quality electric and other pre-set sharpeners. Tools are important for professionals as they have to do a lot of sharpening without spending too much time at it.

Others still use whetstones because of their superior sharpening quality.

All chefs will have honing steels on-hand to keep their knives polished during use and performing to their best ability.
