Top 5 Sharpening Stones - March 2023 - Top Rated (2023)

All edges, from pocket knives to ax heads, benefit from regular sharpening. Although there are a number of machines available, working by hand is still a quick and efficient way to ensure a sharp blade.

However, there are dozens of whetstones available made from different materials of varying grades, so determining which one you need is not easy. Fortunately, we're here to help you choose the right sharpening take care of your knives.

A sharp blade is actually safer than a dull one. A dull blade tends to slip off whatever you're holding and can cut your hand. A sharp blade cuts through the object easily and precisely.

sharp vs polished

Is there a difference? A lot of people confuse the two tasks, but yes, there is a difference. Which one you should do will determine which sharpening stone you buy.

Scharfis the attachment of a sharp edge to a knife or cutting tool that has become blunt through use. This also applies to repairing a damaged edge. Sharpening creates the edge when a blade fails to cut.

polishingIt's regular maintenance that gets a razor sharp edge. It's a process that can take only a few seconds and is done regularly to keep the tool sharp in everyday use. For example, many cooks use a "steel" to perfect their tasteMesserevery time you use them. At the other end of the spectrum, meticulous craftsmen can spend hours sharpening and polishing an ultra-fine edge on oneMesser, chisel or sword.

"A 'steel' is for polishing, not for sharpening. If he can't get a dull knife back into shape in a dozen strokes, the knife should be resharpened."

Choosing a whetstone

Two factors determine the choice of sharpening stone: grit and material. And the type of sharpening you do most often will determine whether you need a bench, pocket, or combi sharpening stone.


The grit indicates how coarse or fine a whetstone is. Typically this is between 400 and 8000, although finer specialty stones are available. They may also be described as coarse, medium, fine, or extra fine, which is less helpful.

  • Dick:Grits of 400 to 500 are considered "coarse". It is used for initial sharpening of a very dull blade and for restoring a dull blade. It's also what you might use on a sword ormowerSound

  • Bad:Grits from 1,000 to 3,000 indicate a general purpose or "medium" sharpening stone. It gives a sharp but not razor sharp edge that is acceptable for many home and outdoor applications.


  • GUT:4000 grit and up is a "fine" sharpening stone (sometimes referred to as a finishing stone). This is the case when you need the extra sharp edge, for example with carving tools. These are the grains used for sharpening.

Diamond whetstones may use the same grading system, but often do not. Sometimes you will see a particle size in microns. A micrometer is one thousandth of a millimeter. The lower the number, the finer the grit. Below is a rough comparison:

  • 400 grains:45 Microns

  • 800 grains:25 Microns

  • Grain 2000:10 Micron


Other factors besides grit affect how well the sharpening stones work, so we also need to pay attention to the material.

Ölsteine:Many people will recognize a carborundum (silicon carbide) stone. These relatively soft materials have been a feature of homes and workshops for centuries. Your father or grandfather could have had one. There are three types of oil stones that are commonly available: silicon carbide stones, Arkansas stones (made from novaculite traditionally quarried in Arkansas), and alumina (also called Indian stones). All of these stones require oil as a lubricant to aid in the cutting process. Some may use water, but it's important to check.

  • Advantages:


    • If you are looking for a cheap all-purpose sharpening stone, an oil stone offers a perfectly adequate and inexpensive solution.

  • Opposites:

    • The surface can become smooth and glassy as cement slurry and small particles fill the sand.

    • These stones often wear out and lose their shape. A shallow groove is usually formed in the center as this area is used more than the edges. Experts recommend several ways to restore the finish and flatness, including cleaning with kerosene or rubbing with a sheet of sandpaper.

water stones:Water stones, like oil stones, can be made of aluminum oxide or silicon carbide. There is also a highly prized natural material called siliciclastic, quarried in Japan, that can be used to make extremely fine whetstones. Most waterstones use the same materials as oilstones, but the binder that holds them together is different. These stones use water as a lubricant. Water stones need to be soaked before use, but this only takes ten minutes.

  • Advantages:

    • The surface quickly breaks up and reveals new edges.

    • Sharpening is much faster than with oil stones.

    • These are not glazed.

    • These are easier to restore if they lose their shape.

    • If you are looking for an inexpensive all-purpose sharpening stone, a water stone offers a perfectly adequate and inexpensive solution.

    • If your goal is to develop the perfect cutting edge, you probably prefer a Japanese waterstone.

  • Opposites:

    • Waterstones are soft, so they wear out faster and lose their shape.

    • Fine Japanese waterstones are very expensive.

Ceramic sharpening stones:Ceramic whetstones are made by combining aluminum oxide and ceramic powder in a process called sintering — heating and compressing the materials until they come together.

Diamantschleifsteine:You can expect the hardest natural substance to make a good whetstone, and it will if you choose carefully. These stones are made of industrial-grade diamond particles that are attached to a metal or plastic backing using special adhesives. With many very hard and sharp edges, they generally require much less effort than other whetstones. Although water is often recommended as a lubricant, you don't need it, giving these stones greater versatility.

  • Advantages:

    • Diamond stones are durable.

    • These stones are versatile.

    • Diamond stones will not tarnish or warp.

    • Some diamond whetstones are perforated to remove dust and dirt.

    • Some stones are solid slabs to prevent the edges of knives or tools from catching in the holes.

    • These stones are great for general sharpening. If you have a few bucks more, good quality diamond stones are the best all-around sharpening method.

  • Opposites:

    • Diamond particles can be very small or widely spaced resulting in an inferior product.

    • Fine-grain diamond stones are rare and expensive, so they're not the best choice for sharpening.

Bank, pocket or combination stones

Bank:If you want to sharpen a variety of itemspocket knifeFor garden shears you need a large bank stone. The common eight and ten inch sizes offer you the space you need and good stability. A stand is nice, as is a protective case when you're not using it.

Bag:Pocket sharpening stones can be small versions of bench stones or have handles. If you need something very portable, there's plenty to choose from.

Combination:Both bench and pocket sharpening stones are typically two-sided combinations, giving you a coarse or medium grit on one side and a medium or fine grit on the other. This is usually cheaper than buying individual bricks and saves space. Specialists often opt for individual stones, and many design their own "cutting station". If accuracy is important to you, you can find several ideas online.

expert tip


It takes time to learn the correct grinding technique. Some blades can only be crafted by hand. With others, like chisels, you can purchase a sharpening/sharpening guide to ensure the cutting edge is at the correct angle to the stone.

You can expect a payment15 $ bis 650 $for a whetstone, depending on the material and grit.


You can find a perfectly acceptable double grit oilstone that will retain all of your propertiescocinaand outdoor knives in good condition forabout $15. Between$15 and about $25, you can find all kinds of portable or collapsible whetstones that are great for camping trips or to keep in a drawer in your houseFan.

Middle area

High quality oil and water stones have similar prices. Silicon carbide versions range from approx$20 bis $65. The same applies to the stones of India. Combining Arkansas stones can cost$ 50 bis $ 100. Diamond stones are often considered the most expensive option you can afford$70 or morefor one. Think how long they last. They are often very economical in the long run. However, beware of cheap diamond sharpening kits (often sold in packs of three different grades). They may seem like great value but you will have a hard time finding many diamonds there! If it seems too good to be true, it is.


For the perfectionist there is nothing more beautiful than the fine grains of Japanese ceramics and waterstones. Nothing beats the price either. A 30,000 grit sharpening stone (also called a lapping stone) may be the pinnacle of sharpening, but it will set you back$350 and $650.

did you know

The term "sharpen" is not a misspelling of "wet". It has nothing to do with water. The word dates back to the 17th century and is another word for sharpening. Something that "wettes" your appetite is another way of saying it whets your appetite.

  • Be patient.Learning to sharpen properly takes time. There are some great videos online demonstrating the technique. It is important not to rush into anything. This tends to cause the blade to vibrate, which does more harm than good. Smooth, even strokes allow you to maintain the correct angle.
  • Get the right angle.One of the key factors when sharpening cutting tools is the right angle. For most household knives, this is about 20 or 21°. Japanese manufacturerchef's knifeI recommend 17°. The bench plane knives should be sharpened to 30°. Always check.
  • Use the right sharpening tool for the job.You will get the job done faster and get a better result. The whetstones we've discussed are great for all types of flat blades, but the cutting edges come in many different shapes. Luckily, there are dedicated sharpeners for serrated blades, woodworking gouges, secateurs, etcchainsaws.
  • Clean and dry your whetstone before storing it.It can be as simple as a quick swipe and rarely lasts more than a minute or two. If you don't clean the stone, residue can attack the surface.

Most whetstones benefit from a lubricant, but it's important to use the right one. Some oils destroy the structure of a water stone.


frequently asked Questions

Q. Can I sharpen ceramic knives?

A.Ceramic knives should stay sharp much longer than steel knives. Ceramic material is extremely hard, almost as hard as diamond, making it very difficult to sharpen. These knives can even wear down the surface of a diamond whetstone. If you need to sharpen a ceramic knife, we recommend contacting the manufacturer. Most will offer to do this for you when you return the knife.

Q. Should I use water with a diamond whetstone?

A.A diamond whetstone can be used with or without water, but tests have shown that you can sharpen your blade faster with water. It's also easier to clean afterwards - wipe with a dry cloth. Using a dry diamond stone will leave a dusty residue that is difficult to remove. Please note that you should never use oil on a diamond stone.

Q. Is there a better way to sharpen a leather strap than a fine whetstone?

A.It's more a matter of personal preference and the type of blade you're sharpening. Some people love to use a leather strap to add a delicate edge to a blade. Hairdressers have been doing it with razor blades for over a hundred years. But the preparation can be a bit of a chore, and like all grinding techniques, it takes time to master. Also, the natural "give" of leather does not lend itself to chisels or heavy blades such as machetes and butcher knives.
