What Are Sharpening Stones?
Sharpening stones is a collective term used for all stones used to sharpen anything with an edge. There are natural sharpening stones that are taken directly from its natural environment and synthetic stones that are developed by manufacturers.
Sharpening stones have different grades. Each grade refers to the grit size of abrasive particles embedded in the stone. The grit size is delineated by a number indicating the stone’s abrasiveness. A high number will indicate a smaller abrasive grain, thereby producing a finer abrasive product, whereas a low number will indicate a larger abrasive grain thereby producing a coarser abrasive product.
Keep reading to learn more about the various types of sharpening stones.
Why Do You Need a Sharpening Stone?
A good quality knife or cutting tool should last you a lifetime. Unfortunately, they don’t.
Knives and any edged tools deteriorate over time due to regular use or (possibly misuse). It’s unavoidable. They become dull, ineffective and accident-prone.
Not to worry though! That’s what sharpening stones are for.
Sharpening stones will help keep all your cutting tools staying sharp and performing to a peak level as well as extend your blade’s lifespan.
If you want to maintain that razor-sharp edge on all your knives and edged tools, using good quality sharpening stones is the way to go and they should always be part of your sharpening toolkit.
What Should You Look For in a Quality Sharpening Stone?
When you’re searching for a sharpening stone, there are a few things you should be mindful of before buying one.
The Grit Perhaps the most important element of your sharpening stone will be the grit. Grit basically dictates the sharpening power of your stone and how it will perform.
Sharpening stones have different grits and each grit will sharpen your knife differently.
There are coarse, medium, fine and finer grit stones each referring to the size of the abrasive particles within the stone. Each grit size will have a number indicating the degree of a stone’s coarseness or fineness. The lower the number, the coarser the surface. Conversely, the higher the number, the finer the surface.
The Size Does size matter? In this context, not really. An ideal size for a sharpening stone will depend on the type and size of the knives or edged tools being sharpened.
A 6” stone would be considered a small stone. An 8" stone is the most commonly used size and anything larger than 8” would be considered generously-sized. There are also stones smaller than 6" called pocket stones that are great for on-the-go sharpening.
Simply put, larger knives and edged tools will require larger stones while smaller knives, like pocket knives, are perfect for smaller stones.
If you're looking for something more portable, check out our article on the top 8 best portable knife sharpeners.
The Material As mentioned above, sharpening stones may be natural or synthetic. Generally, modern synthetic stones are considered to be more superior in their sharpening performances. The abrasive particles can be controlled which allows the stone to cut faster or slower.
Natural stones, on the other hand, are often treasured for their natural beauty and since they are so rare, it makes them a valuable collector’s piece.
Additionally, no two natural stones are alike. There are even some rare natural stones that have finer abrasive particles than that which are found in artificial stones.
The Lubricant Most sharpening stones will require a lubricating substance, either oil or water, which helps in the sharpening process. However, some stones can also be used dry. It really comes down to personal preference.
Keep in mind though, once you use oil, you will need to continue using oil since oil and water do not mix.
User-Friendly Stones that require constant flattening, soaking and cleaning, or ones that take a little longer to form an edge can be cause for frustration for many sharpeners. So remember, your willingness to perform regular maintenance will be a requirement when choosing your stones.
Stone or Stones Just how many do you need? It really depends on how much sharpening you do. Essentially, if you do a considerable amount of sharpening, you should have at least three stones. One to form a rough edge, one to sharpen and one to hone.
If you only sharpen on occasion and do not need to reshape an edge (remove any chips or nicks), a combination stone will work just fine.
Your Budget We all have a budget. We may even stretch our budget if something is worth paying the extra cost.
Everyone has heard the expression, “You get what you pay for.” There is always some truth to that saying, but it does not necessarily mean that the most expensive stone will give you the best results.
Effective and efficient sharpening can be achieved at various price points. It really just comes down to choosing the best one for your needs and what you can easily afford.
Can’t wait? Click here to read the reviews of our top 8 picks.
What Are The Different Types of Sharpening Stones?
There are three common types of sharpening stones - oil stones, diamond stones and water stones.
Oil Stones These types of stones tend to hold their flatness shape which provides for a more sturdy sharpening surface. Some natural stones come pre-bathed in oil directly from the manufacturer. Therefore, it is recommended that these stones continue to be used with oil.
As I mentioned above, once you use oil on a sharpening stone, you will need to keep using oil since oil and water do not mix.
Diamond Stones Since diamond stones are considered to be one of the hardest materials, they will continue to remain flat for a long period of time. Although they can be used dry, it is recommended they be used with water.
Water Stones For beginners and seasoned sharpeners alike, these stones are a great choice since they are easy to use and require very little cleanup. As the name suggests, these stones are used with water.
Below is an in-depth look at the different types of stones.
Oil stones have been and still are the traditional sharpening stones used. This type of stone is typically made with natural materials but a few man-made options are available.
As the title of the stone suggests, this type of stone would be used with an oil lubricant to help the removal of swarf (metal filings).
There are three common types of oil stones - Arkansas, India and Crystolon.
This sharpening stone is a unique rock mined in the Ouachita Mountains of Arkansas and Oklahoma. It is made of natural material called Novaculite which is composed of quartz crystals.
While this type of stone is considered to be an oil stone, water can be used. There is a theory that by adding a bit of dish soap with the water helps keep the stone from clogging.
Arkansas stones are not measured by their grit size, but by density and hardness.
There are four grades of an Arkansas stone: Soft, Hard, Black and Translucent. The most popular grade is the Soft Arkansas Stone as it provides a keen, sharp edge on knives or tools in minimal time.
Keep in mind, the softer the stone, the coarser the stone surface feels. The harder the stone, the smoother, glassier the stone surface feels.
Norton India Stones
By contrast to the natural Novaculite Arkansas Stones, oil stones made from aluminum oxide have become an increasingly popular man-made option best-liked for providing durable smooth-cutting edges on many tools.
When compared to an Arkansas Stone, India Stones are considered to be more coarser and can be used together with the Arkansas Stones covering all the grit levels from coarse grit to ultra-fine grit.
India stone grades come in coarse, medium and fine. They are pre-soaked in oil, so trying to use water with them would be ineffective.
Norton Crystolon Stones
These types of oil stones are made from silicon carbide and are considered one of the fastest cutting stones. They are the preferred choice for quick work when speed of sharpening outweighs the need for a fine cutting edge.
As a general rule, Crystolon Stone is used first for coarse grit sharpening followed by an India Stone and finishing off with an Arkansas Stone.
The Diamond Sharpening Stone has small synthetic diamonds that are fixed to a hard plate (a/k/a Diamond Plate) creating an abrasive surface that is much harder than any other sharpening stone.
As one of the toughest materials on the planet, it wouldn’t be easy for a stone to become worn out that is covered in diamonds. And because of the diamond’s hardness, the stone will continue to remain flat for a long time, provided of course the stone is properly maintained.
Diamond stones may be used dry, but it is recommended that it be used with water. You should not use oil because once you do, water will no longer work.
By adding a little dish soap to the water can help reduce friction and keep your stone’s pores from clogging.
Diamond stones are used for different purposes. Based on the diamond’s density on the plate, there are two ways to sharpen with a diamond stone.
The most common of the two is called the Non-Continuous Diamond. This type contains small holes to catch any swarf. Using this type of surface, sharpening will be much faster and easier to use.
The second of the two is the Continuous Diamond. This type of surface is the preferred method when you are sharpening tools which include points that might otherwise get caught in the small spaces of the non-continuous diamond surface.
Both types can be made with either monocrystalline or polycrystalline diamonds. However, monocrystalline diamonds are the preferred choice because of its ability to sustain its structure giving the stone greater longevity.
With anything, there are advantages and disadvantages. Two advantages of the diamond stone is its sharpening speed and the flatness that it retains. As a matter of fact, extra-coarse diamond stones are sometimes used to flatten oil stones and water stones.
The disadvantage of the diamond stone is its cost. While these stones may be one of the most expensive in comparison to other stones available, diamond stones will last much longer, making it worth paying the higher price.
Like oil stones, water stones can either be natural or made of synthetic materials. However, they are softer than oil stones.
As its name suggests, these stones are used with water as the lubricant (as opposed to oil) which develops a fast-cutting slurry.
Synthetic water stones are generally made from Aluminum Oxide which is the same abrasive material used in India stones. However, water stones have a much higher-quality composition that produces a softer stone.
Being softer allows the abrasive material to break away more easily, exposing new sharp material, which ultimately promotes faster-cutting.
The higher-quality grain composition will leave a much finer finish than India or Crystolon stones making them ideal for final edge sharpening on all your edged tools.
Water stones are also much easier to clean than oil stones since they won’t leave any oil residue on your tools. Due to its improved performance and preference for water over oil, it’s the preferred sharpening stone.
A well-known water stone are the Japanese Water Stones.
Japanese Water Stones
Japanese water stones can either be natural or man-made. Like most whetstones, Japanese natural water stones are sedimentary.
Notwithstanding, the quarries in Japan had rocks which incorporated additional composition containing fine silicate particles in a clay form, making them a bit softer than Novaculite which is found in Arkansas Stones.
Japanese water stones should be soaked in water prior to use.
Finding a good quality sharpening stone can be quite overwhelming for some. Since there are so many options, where does one begin?
