Sharp pebble is a relatively new company with a reputation for producing best quality sharpening stone.

It’s pleasantly surprising that they have gained so much popularity in a very short period. If they don’t let the standard drop, they should dominate the kitchen utensils market for a long time.

This whetstone has two different sides with two different grit sizes. That means you are getting two different stones at the price of a one.

While the blue side (1000 grit) can be used to restore the knives to their original sharpness, the white side (6000 grit) can be employed to give the blade an exceptional finish.

Not only this thing comes with a bamboo base, but it also includes a plastic substructure to secure the stone in the base. As if that wasn’t enough, the bamboo base also has a rubber bottom to provide additional traction.

If you are a rookie at this, you are gonna love the angle guide. Aside from maintaining the correct angle all the time, it also provides additional protection to your fingers.

However, if you are proficient at this, you may prefer the free-hand sharpening which allows you to use your thumbs as the guide.

Since this one is the best water sharpening stone, it needs to be soaked before use. Furthermore, to counter the dwarf, you gotta douse it regularly while sharpening.

It’s worth mentioning that the white side retains water for a longer time and thus doesn’t need to be lubricated as often as the blue side.

The softness of the finer side is both a blessing and a curse. A curse because it causes the stone to wear away pretty fast. A blessing because the erosion removes old abrasive material and exposes new ones, which leads to improved cutting rate.

Highlighted Features:

  • Features both finer and coarse grit.
  • Includes Bamboo base.
  • Comes with an Angle guide.
  • Has Rubber bottom.

2. Sharpton Ceramic Knife Sharpening Stone

Regarding performance and materials, there’s literally no difference between this one and Sharpton pro-US version, which costs twice as much as this one.

The only difference is this one includes no warranty. So, if you are okay with having no warranty, which you’ll probably never use, then the kuromaku ceramic stone is a no-brainer.

Individuals with a busy life will appreciate the fact that this guy requires minimum maintenance. Since it’s a ceramic sharpening stone, no need to soak it in water or lubricate with oil before use.

On top of that, it doesn’t create much slurry eliminating the need of keeping additional water on hand.

When it comes to giving the blade a hair-popping edge, this thing works like a charm. At 12000 grit, this is one of the best knife sharpening stone out there with the capability to make your knife as new as the day you bought them. Moreover, it works super fast and creates burr in double-quick time.

Apart from being used to store the stone, the included plastic case works as a stand to prevent a skid, while you are working on the knives. There’s also a rubber bottom on the plastic case so that the stone doesn’t walk across the counter during sharpening.

Unlike other water stones, you won’t need to flatten this thing after every use. It has a harder surface than the others and requires to be leveled only once in a while. Nonetheless, it would have been better if the sharpening stone set came with a flattened.

Since it’s the Japanese version, the instructions are also in Japanese. It would have made things a bit easier if they were in English. Another thing you need to keep in mind that, ceramic stones aren’t shatterproof and must not be dropped on a hard surface.

Highlighted Features:

  • Affordable price
  • 12000 grit stone
  • Less maintenance
  • Plastic case functions as a holding base
  • Features Rubber bottom
  • Requires Sporadic flattening

3. Utopia Kitchen Knives Sharpening Stone

  • 600/1000 Grit Double Sided Sharpening Stone. L 7"x W 2.4"X H 1.06. The fine surface prevents the cutting edge from damage when sharpening. And the sharpening will be much efficient. Slip-resistant...
  • Abrasive Material is Carbon Steel. Grade: Coarse/Fine being one side 600 grit, the other 1000 grit. Perfect for do-it-yourself projects.

If you are someone who’s unwilling to compromise on quality and at the same time loathes spending big bucks on a stone, then you should certainly check this out.

Because believe me, quality whetstones do not come any cheaper than this. Moreover, they haven’t cut any corners to keep the price low.

The 600/1000 grit combo gives you a lot of options. Knives that are extraordinarily dull or have completely lost their edge can rub shoulders with the 600 grit side.

Meanwhile, the finer 1000 grit side can be utilized to put an edge on the regular knives. That said if you wish to give the blade a super smooth finish, you gotta buy yourself a higher grit stone.

For stones below 3000 grit aren’t that great at honing the edge. A leather strop could be a viable alternative to help you fine-tune the blade.

A sudden slip during sharpening can cause you to cut your thumbs. Thankfully, the non-skid rubber bottom will make sure it doesn’t. The base is as sturdy as it gets and doesn’t require you to use a wet towel underneath.

Even though manufacturers permit usage of oil, you’d be well-advised to avoid them. Frequent usage of oil hardens the stone, which leads to diminished effectiveness.

Although it is recommended that the stone is waterlogged for a while before use for the sake of better performance.

Regarding size, this sharpening stone is 7 inches long and should accommodate medium-sized knives easily. However, the knife could slide off the stone while sharpening longer blades. So, if you aren’t paying attention, it may lead to a change of angle.

Highlighted Features:

  • 600/1000 grit combo
  • Includes non-slip rubber bottom
  • 7 inches long
  • Comes at a low-price

4. Naniwa Chosera 5,000 Grit Sharpening Stone

Shrimp Stamp SS-5000 Professional Super Ceramic Whetstone with Base...
43 Reviews
Shrimp Stamp SS-5000 Professional Super Ceramic Whetstone with Base...
  • Size: 8.3 x 2.8 x 1.0 inches (210 x 70
  • Grit size: #5000 (for super finishing)

Since the age of samurai, the Japanese people have been perfecting the art of sharpening blades. So, it doesn’t come as a surprise that most of the well-known whetstone manufacturers are based in Japan.

Chosera 5000 grit is also manufactured in Japan and comes from a very reputable company called Naniwa Abrasive MFG.

Performance-wise, it’s impossible to find a flaw. Fully capable of giving the blade a smooth reflective finish by dint of grit as high as 5000. Moreover, it allows you to put a sharp edge on blades without much hassle or time.

Though incapable of working on sushi knives, it is a cut above the others when it comes to grinding regular kitchen knives.

This stone is pretty soft. That means it gives away new abrasive substance easily. As a result, the stone cuts quickly and takes fewer swipes than others to sharpen the knives.

When it comes to aesthetics, it fails to score a point with me. The stone is grey colored and looks kinda pale (don’t get deceived by the picture).

Moreover, due to being almost black, the particles build-up can’t be easily seen. I wish the stone color had been white or some other bright color.

I am not a huge fan of the plastic base that it comes with. It’s not up to the scratch and often fails to keep the stone in place. But that shouldn’t be a deal-breaker as you can always put something underneath the base to make the stone stationary.

There’s a misconception among some people that this one is a splash and go stone (means no soaking). It isn’t and needs a few minutes of soaking prior to use.

A disclaimer: you may have to wet the stone regularly during work as this one has quite an appetite for water.

Highlighted Features:

  • Very soft
  • Includes a plastic base
  • 5000 grit stone
  • Needs to be saturated

5. Tatara Sharpening Stone

TATARA | Japanese Whetstone 3000/8000 Grit | Double Sided Knife...

TATARA | Japanese Whetstone 3000/8000 Grit | Double Sided Knife...
  • RAZOR SHARP: Knife sharpening stone set helps you slice through anything with ease when you have a truly razor-sharp tool using your knife chisel sword and axe sharpener.
  • PROFESSIONAL: Made from professional grade Aluminum Oxide, so expensive oil is NOT required; just use some water and you're good to go. Works better than a diamond sharpening stone for knives.

Tatara, a Japanese company, manufactures a wide range of kitchen products including knives and sharpening stones.

They are renowned for producing the best water stones available. This stone is no exception and loaded with plenty of attractive features.

One of the most significant advantages of this stone is its versatility which allows you to sharpen knives, chisel, sword, and other stuff with equal effectiveness.

That’s why the 3000/8000 grit combo makes it the ideal stone to lengthen the expiration date of your kitchen cutlery and other instruments.

Let me inform you though that, while the 3000 grit is perfectly able to bring an elegant edge to your kitchen knives, it’s not coarse enough to fix blades that are nicked or gone through years of abuse. Nevertheless, the 8000 grit is impressive and manages to provide the blade a mirror sharp smoothness.

I recommend putting the stone in water for a while before you get started. Getting saturated boosts its performance markedly. And one more thing, the blade leaves residue on the surface, which needs to be washed off with water to maintain the effectiveness.

The non-skid bamboo case that comes with the stone is of good quality. It’s on par with other quality holders and looks solid enough to inspire confidence. However, the absence of a gripping surface is surely a problem.

If you are a rookie at sharpening, the angle guide should get you started. Helps you with the angle and safeguards your thumbs from the vicious edge of the knives.

What bugs me most is that the stone wears away pretty quickly. In addition, you need to use a flattener frequently to keep the surface smooth.

Highlighted Features:

  • Highly Versatile
  • 3000/8000 combo grit
  • The non-slip bamboo case provides stability
  • Angle guide for beginners

6. Smith's Tri-6 Arkansas Tri-Hone Sharpening Stone

Smith's - TRI6 TRI-6 Arkansas TRI-HONE Sharpening Stones System Gray

Smith's - TRI6 TRI-6 Arkansas TRI-HONE Sharpening Stones System Gray
  • 2 Arkansas stones (Fine & Medium) & 1 Coarse synthetic stone.
  • Stones Mounted on Rotating Molded Plastic Triangle for Easy Stone Rotation and Identification

Having been around since 1886, they know the market very well. Though smith’s produce a variety of kitchen utensils, they are well known for their sharpening products.

What makes them stand out is their innovativeness which allows them to constantly offer something new and interesting to the consumers.

What makes this product truly special is the incorporation of three different stones. While the finer one is a natural Arkansas stone, the coarse one and the medium grit stone are made of synthetic materials.

Moreover, when it comes to durability, this unit can give the best whetstone a run for the money.

When you pick up the unit, you will notice a coarse stone with low grit. Be careful and don’t use it unless the knives are badly messed up.

Typically, the medium grit stone should be more than sufficient in reimposing the edge. But if you are looking for a razor-sharp finish, the higher grit stone has got your back. 

Unlike my previous recommendations, oil has a significant role to play here. By rubbing oil over the surface, you can remove the residue and keep the stone in good condition.

Thankfully, the manufacturers have been considerate enough to include a free bottle of honing oil with the package. You’ll also be getting a plastic case to keep the stone from sliding and slipping. It’s got rubber feet on the bottom to keep the base stationary.

Overall, this one is pretty sturdy and shouldn’t skate away during work. The fact that this thing also includes an angle guide makes the whole package all the more attractive.

The only issue I have with this stone is its small size. Likely to have adjustment problems, especially if you are accustomed to big stones. Though small blades such as pocket and hunter knives won’t present any difficulties, the larger blades are a different thing.

Highlighted Features:

  • Features three different stones
  • Includes oil for lubrication
  • Comes with a plastic case
  • An angle guide is provided for the rookies

7. King 1000/6000 Grit Combination Whetstone

KING KW65 1000/6000 Grit Combination Whetstone with Plastic Base
4,021 Reviews
KING KW65 1000/6000 Grit Combination Whetstone with Plastic Base
  • King 01096 1000/6000 Grit Deluxe Combination Stone
  • King brand known for quality and affordability

The root of King, which is a subsidiary of Matsunaga Corporation, can be traced back to Japan. I think the name “king” befits them as they are truly the leader in this industry in terms of sale and quality. Their products can describe in three words: quality, durability, and versatility.

I don’t want you to have any misconception about its ability; this thing isn’t meant to fix blunted or dented blades.

That’s because this thing is a finishing stone and designed to fine-tune the edge rather than fixing it. To whet knives that got knick in the edges, you’ll need something with a far lower grit.

However, this 1000/6000 grit combo is an excellent choice for regular maintenance and ideal for making short work of knives that are average dull.

So, if you have knives that aren’t chipped or terribly blunted and requires routine sharpening, then this one is the right fit for you.

The included plastic case works as a holder to keep the stone firmly planted on your countertop. It secures the stone and prevents it from sliding so you can go about working the blade without any worries.

Regarding material, it’s a synthetic stone and mostly made of ceramic. Therefore, unlike the Arkansas tri-hone sharpening stone, you won’t need any expensive oil to lubricate the stone. But you can moisturize the stone with water for smooth performance.

Since the stone is quite soft, the blade could dig into the stone if too much pressure is applied. So, caution is advised while you are polishing the edge.

Another thing that I’d like to warn you about is the packaging. A lot of people have complained of poor packaging and receiving chipped stones.

Highlighted Features:

  • 1000/6000 combo grit
  • Plastic case comes with the unit
  • Synthetic and predominantly made of ceramic
  • Reasonable price

8. Chosera 1,000 Grit Stone

1,000 Grit Super Ceramic Water Stone with a Base (Japan Import)
239 Reviews
1,000 Grit Super Ceramic Water Stone with a Base (Japan Import)
  • Size: 210 x 70 x 25 mm
  • Accessory: Dressing stone (cleaning stone) 65x47x32 mm 1 piece

I bet you can’t go wrong with Naniwa stones. These stones make blades so sharp that it will cut through literally everything.

On top of that, these stones are insanely easy to use. In fact, you can use the stone even if your sharpening skills stink.

You don’t wanna buy a stone every year. Nor do you want to get a stone that takes ages to put an edge on the blade. You want something that’s durable and cuts fast.

Luckily, Chosera 1000 grit, which is probably perfect for kitchen knives, fulfills both the criteria. Due to being remarkably hard, it wears very slow, and cuts swiftly.

There’s a plastic base attached to the stone (contrary to the description), which does a decent job of holding the stone in place. Could it have been better?

Yes. But that’s not a huge problem and could be quickly sorted out with a piece of cloth. There’s also a cleaning stone to help you prepare the surface for sharpening.

However, if you have something that’s heavily damaged, then you will need a lower grit stone like 400-600 grit. This one is ideal for medium grinding and blades that haven’t lost their sharpness completely.

Being a splash and go stone; this one doesn’t need any soaking. That means you won’t have to spend those extra minutes preparing the stone. So, if you are someone who is time-conscious and would benefit from skipping all the prep, you should go for this stone.

In my opinion, the price seems a bit excessive. But then again when do Naniwa stone come cheap? After all quality products tend to be expensive. So, if the price doesn’t put you off, this one could be a really good choice.

Highlighted Features:

  • 1000 grit stone
  • Plastic base affixed to the stone
  • Very durable
  • Cuts quickly

  • HIGH QUALITY WHETSTONE 3000/8000 GRIT: Chefic sharpening stone is made from professional grade white corundum with 17 processes, which is durable, corrosion resistant and heat resistant. The 3000...

Let’s just get the elephant out of the room immediately; the product description is misleading.

There’s no way in hell this thing’s a 3000/8000 grit combo. In truth, this should be something around 800/1200 grit. They have probably done this to avoid copyright issues, but surely not cool.

So, what’s this thing doing in my stones list? Despite the misleading description, I recommend the Bearmoo stone for three reasons.

First, it cuts really quickly and forms burr super fast. Secondly, it sharpens extraordinarily well and can breathe new life to knives that you have lost all hope for. Third, this thing comes at an incredibly low price.

Weighing 19.75 oz, it’s pretty heavy. That’s a good thing as it helps the stone to remain in place while you are pushing the blade across the surface. And what’s more, you will also be getting a silicon base and two rubber holders with the stone to ensure that the stone doesn’t scoot around in the middle of work.

Avoid buying honing oil for this. Yes, oil is allowed, but water works much better on this.

Considering its brittle nature, it’d be better if you didn’t soak the stone for too long lest it gets too weak to work on. 5-10 minutes of immersion should help you achieve the desires result.

I like the fact that they have included an easy-to-understand manual guide explaining the whole process.

The user guide is pretty detailed and super helpful. It will tell you to use the entire surface, so the stone remains flat and you don’t have to use a lapping plate.

Being 7-inch-long, the Bearmoo stone allows you to whet large knives easily. However, it would have been very helpful if the stone were an inch wider.

Not that it’s not wide enough, it’s just that working on an extensive stone seems a bit more fun. If you are looking for the best of best sharpening stones, then look no further.

Highlighted Features:

  • Includes a silicon base
  • A combination of 3000/8000 Grit
  • Two plastic holders for additional protection
  • 7 inch long
  • Weighs 19.75 oz

10. Super Ceramic Best Water Sharpening Stone

400 Grit Super Ceramic Water Stone (Japan Import)
240 Reviews
400 Grit Super Ceramic Water Stone (Japan Import)
  • Keep your knives razor sharp
  • Wide surface for long knives

To be honest, I’ve got no clue as to why this one is called a super ceramic stone, and neither seems to have anyone else. Made by Naniwa, this stone is of Chosera series. In terms of performance and materials, it’s pretty similar to the Chosera1000 grit.

There are a lot of features that I like. To begin with, it’s a 400 grit stone, which is really coarse. That means knives with dents or visible imperfections can soon return to work.

So, get ready to put wicked edge even on the dullest blades of yours and have them gleaming. For the very same reason, it fails to be a finishing stone. To get the right finish, you should get yourself a leather block and strop the blade with it.

Another thing you need to be aware of is that this stone needs to be squared from time to time. Failure to keep the surface level can hamper its performance considerably.

Another cool feature is that it’s a splashing go stone. That means no immersion or preparation before use.

However, you should keep water at hand while sharpening so that you can remove the swarf build-up easily. The only real flow that I found in this otherwise great stone is it takes a bit longer than others to remove particles.

Compared to other stones, they require some extra swipes. So, if you have 4-5 extra minutes to spare, then this shouldn’t be a big issue.

The plastic base isn’t the greatest but discharges its duties reasonably well. Does what is required of it which is to keep the stone tightly secured during the work.

Something else to pay attention to is its width which is large enough to accommodate long and huge chef knives.

Highlighted Features:

  • 400 grit stone
  • Splash and go stone
  • Comes with a Plastic base
  • Has a wide surface

Things to Consider before Buying the Best Sharpening Stone:

​1. Type of Stones

Whetstones come in three varieties; oil stones, diamond stones, and water stones. Below I have devoted an entire section detailing the various types of sharpening stones to help you pick the best one. So, there’s no point in repeating myself here.

That’s why I’m just going to go through the advantages and disadvantages of each stone quickly.

Oil Sharpening Stones:

Similar to the water stones, oil stones also come in both artificial and natural materials.

What makes them different from the water stones is that they need to be lubricated with oil instead of water. The oil removes the metal particles build-up retaining the effectiveness of the sharpening stone.

Whereas natural oil stones are usually composed of Novaculite and Coticule, synthetic ones are made of either aluminum-oxide or silicon-carbide.

Advantages of Oil Stones:

  • Able to establish a crazy sharp edge on the blade
  • Relatively inexpensive
  • Hardly needs any flattening

Disadvantages of Oil Stones:

  • Cutting speed is a bit slow
  • Requires expensive oil to lubricate the stone

Water Sharpening Stones:

While natural water stones consist of quartz, artificial water stones are typically made of Silicon Carbide and Aluminum Oxide.

Performance-wise, synthetic stones are considered superior to the natural ones. For, they are not only faster in removing particles but also allow you to maintain consistency of particle size.

The astounding beauty of natural stones compensates for what they lack in performance. Moreover, the fact that natural stones are distinct and extremely rare makes them even more appealing and valuable.

It goes without saying; these stones cost a lot of bucks.

Advantages of Water Stones:

  • Cuts faster than the oil stones
  • Unlike oil stones, they require only water to lubricate the stones
  • Easy maintenance

Disadvantages of Water Stones:

  • Needs frequent flattening
  • Wears faster than other stones

Diamond Sharpening Stones:

Similar to the water stones, oil stones also come in both artificial and natural materials.

What makes them different from the water stones is that they need to be lubricated with oil instead of water. The oil removes the metal particles build-up retaining the effectiveness of the sharpening stone.

Whereas natural oil stones are usually composed of Novaculite and Coticule, synthetic ones are made of either aluminum-oxide or silicon-carbide.

Advantages of Diamond Stones:

  • The cutting rate is unparalleled
  • No flattening needed
  • Able to function as a flattening stone
  • Extremely durable

Disadvantages of Diamond Stones:

  • Costs a lot of money

2. Grit Selection

Grit range is the most critical aspect of a sharpening stone. It tells you all you want to know about the stones and help you decide whether it suits your purpose. There are various types of grit range. Here we will take a look at them.

Under 1000 Grit:

If you have knives that are extremely blunted or seriously damaged, then you need something that’s very rough.In this case, I recommend 250-600 grit stones which are coarse enough to repair the exceedingly dull or damaged knives.

1000-3000 Grit:

The medium grit stones are ideal for regular maintenance and knives that have partially lost their edge. Though you can’t fix nicked up blades with these, they are great or preservation of the kitchen knives and carpentry tools.

4000-12000 Grit:

Mostly known as finishing stones, these guys will help the blade to acquire a fine edge. The finer grit will make your knives so sharp that the blade will stick in the cutting board while you are slicing vegetables.

3. Non-Skid Base

You don’t want the holder to slide all over the place while you are working on the blade.That’s why you need a base that prevents slipping and keeps the stone in place firmly.

Therefore, make sure that the sharpening stone set includes a non-slip base before you make the purchase.

4. Size and Weight

For ordinary kitchen knives or carpentry tools, you don’t need a very long stone. However, stones that are long come in handy while sharpening large knives. That’s why you should get something that fits your needs.

Regarding weight, the more a stone weighs, the better. It gives the stone stability and prevents it from skidding.

Why You Should Use High-quality Stone

It doesn’t matter if your knife is expensive or cheap, new or old, it can still get dull. Using blunt knives is not only inconvenient but a bit dangerous too. The bluntness makes them unpredictable and prone to slipping, often resulting in minor cuts.

So, if you value the well-being of your fingers, you must keep your blade razor-sharp. But why not use an electric sharpener? Two reasons:

First, electric sharpener requires cautious handling as too much pressure could lead to a scratch or dent.

Secondly, they are way more expensive than the stones.

Top Rated Sharpening Stone Brands in the Market

1. Sharp Pebble

They have established a firm foothold in this industry in a very short period. Despite being a relatively new company, they have managed to build a loyal fan base of their products.

Packed with incredible features, their products are guaranteed to make sharpening a comfortable experience for you. Sharp pebble stones tend to be versatile allowing you to get your money’s worth out of it.

What I like most about their products is that they are beginner-friendly and incredibly easy to use. They also tend to include an angle guide to make things a bit simpler for you.

2. Naniwa

If you have had more than one stones, then chances are one of them is from Naniwa Abrasive MFG. Their chosera stones are probably the most popular sharpening products due to the material, durability, and top-notch performance.

Naniwa stones are comparatively pricier than the others and sit on the expensive end of the spectrum. But when you consider its superior performance and high-quality material, the price seems hardly unreasonable.

3. Sharpton

Sharpton is well known for its Japanese water stones. Their products are geared towards simplicity and making the whole process less time-consuming.

Sharpton stones require little or no preparation before use and create minimal slurry. As a result, you can devote your undivided attention to the sharpening.

Moreover, these stones work real fast and produce burr in no time. The performance, generally speaking, is outstanding, exactly what you would expect from a reputed brand.

4. King

King boasts an enviable track record of producing some unique water stone sets over the last couple of years. Keep in mind that the stones made by them are more of a finisher than a sharpener.

Though their effectiveness is limited with the extremely blunted blades, they can work wonder with the regular kitchen knives. Almost all their products are synthetic and geared towards performance.

5. Smith’s

They have been producing kitchen products since 1886. The fact that they have survived so long in this highly competitive market speaks volume of their high standard.

What separates them from other companies is the novelty their products bring.

For example, Smith's TRI-6 Sharpening Stones System features both natural and synthetic stones to give you a unique experience. Now that’s something unprecedented and attracts consumers to their brands.

What Grit Stones are Best to Use for?

The grit of a sharpening stone refers to the degree of coarseness the stone has. The coarser a whetstone's grit is, the lesser the effort needed to achieve a sharp edge.

However, coarser sharpening stones tend to take off more material from the edge of a blade and can decimate your knife's blade too quickly.The coarser a sharpening stone's surface is, the lower the grit value.

To understand sharpening stone grits, we classify them into different groups:

1. Coarse Grit Sharpening Stones

A very coarse whetstone, one with a grit of 500 or thereabouts, is not useful for actual sharpening of knives. Such stones are designed for rougher work such as setting a new bevel edge on a blade or repairing knives with chipped edges.

2. Medium Grit Sharpening Stones

Medium grit whetstones have a grit value of around 1,000 to 1,500. This is still too coarse to use for fine sharpening of blades. As such, medium grit sharpening stones are usually used for sharpening very dull blades or knives with a newly set bevel edge.

A medium grit sharpening stone will remove enough material to restore a cutting edge. However, the material will not be so much that the edge will be worn away after just a handful of uses.

3. Fine Grit Sharpening Stones

Fine grit whetstones have a grit value of around 4,000. An edge sharpened with a fine grit sharpening stone is going to be very sharp. Such knives are ideal for cutting through tough items like sinews and ligaments.

This is the kind of sharpening stone to use with your kitchen knives when you need to strike a fine balance between sharpness and durability.

4. Super Fine Grit Sharpening Stones

To achieve the sharpest edge on a knife you need a super fine grit sharpening stone. This requires a grit rating of between 6,000 and 8,000. This is good enough to sharpen a blade to a mirror-like smoothness and then honing it to a razor-sharp edge.

How to Sharpen Knives

1. Wet the surface of the sharpening stone by using either water or oil. Keep reading to identify which liquid to use.

2. Place the whetstone on a flat surface such as a chopping board or countertop. If the surface is too smooth, you can place a wet towel on it first to hold the whetstone in place once you start sharpening.

3. Hold the knife by the handle on one hand and place the blade on the whetstone, point first. Use the other hand to apply pressure on the blade and correct the angle at which the blade and stone meet so it is roughly 22 degrees.

Remember that 90 degrees is when the edge of the blade is perpendicular to (straight up on) the whetstone. Leaning a perpendicular blade by half will make the angle 45 degrees. Reduce that angle by another half and that makes roughly 22 degrees.

4. With moderate pressure, move the edge of the blade across the surface of the whetstone, maintaining the angle of contact at 22 degrees

5. Count up a dozen strokes across the whetstone, ensuring that the entire edge of the blade comes into contact with the whetstone each time

6. Flip the knife and repeat another 12 strokes on the other side of the blade

7. Use a fine grit sharpening stone to hone the blade to the sharpness.


To keep your whetstone in top shape and effective in sharpening your knives, you need to ensure it is always clean. The method you use to clean your whetstone depends on whether you wet it with oil or with water.

1. Cleaning a Sharpening Stone Which Uses Oil

If you use oil to wet your sharpening stone then the best way to clean it is by using honing oil.

1. Apply a layer of honing oil on the surface

2. Rub the oil in a circular motion over the entire sharpening surface to remove filings and dirt

3. Rinse the stone by holding it under water until all the grime and dirt have been washed off

4. Dry the whetstone using a piece of cloth or paper towel

2. Cleaning a Sharpening Stone Which Uses Water

If you use water while sharpening blades on your sharpening stone, use warm soapy water to clean the surface. A normal household detergent should suffice.

Use an old toothbrush or an ordinary kitchen scouring pad to scrape off the dirt. Use a combination of lengthy and circular strokes to ensure all the dirt and metal filings are removed. Rinse the stone under water and dry it.

How to Care and Maintain?

Taking proper care of the sharpening stone can go a long way to ensure longevity. Here are a few tips to help you with the maintenance of the stone.

Remove the Metal Flecks

Metal flecks can diminish the effectiveness of the stone drastically. Thus, it’s imperative that you get rid of the embedded mineral filings the moment they start to pop up.

To flush out the metal flacks, apply honing oil on the stone surface. You can use a brush to spread out the oil evenly.

Eventually, you’ll see the metal flack emerging from the pores of the hard surface.

Once the metal flecks start appearing, get a damp towel and wipe the surface gently with it. Make sure that no metal flecks are left behind before washing the stone with water.

Get Rid of the Dirt

Once you spray the WD-40, which is an oil spray with the capability of penetrating stones, onto the whetstone, the dirt will start to materialize.

If you have something that’s really old and has been unused for a long time, you may find yourself in need of an abrasive tool to break up the dirt buildup. Finally, get a damp cloth and wipe the grim off the surface of the stone.

Flatten the Whetstone

To keep the surface even, you got to flatten the stone regularly. Usually, a flattening plate comes with the package, which you can use to make the surface flat and smooth. In case, it isn’t included, you can buy it from any local hardware store.
