Types of Sharpening Stones

Stones used to sharpen knives are found in both natural and synthetic materials. These are rectangular blocks with flat surfaces but differ in characteristics according to their type. They are found in the following three types:

  • Oil Stones
  • Water Stones
  • Diamond Stones.

1.Oil Stones

These stones are made by using Aluminum-oxide or Silicon Carbide. They are man-made stones available in two different material forms. The particles of these materials are bound together by using a binding agent.

The abrasive particles are either made of Aluminum-oxide or Silicon carbide. Aluminum Oxide abrasive particles are very hard and produce dangerously sharp edges.

While both of these materials need oil to lubricate and start to initiate the sharpening process. That is from where these stones derive their name as Oil stones.

2.Water Stones

Water stones are available in both natural and synthetic forms. These stones are called water stones because such stones need water for lubrication.

Natural water stones are quite expensive and are found in Belgium and Japan. Since the 17th century, Belgium is the major exporter of these water whetstones.

These whetstones are available in the highest grids of 8000 and 4000. While the Japanese water stone is becoming scarce now.

It is available near Kyoto city of Japan, once they are found they are cut into regular blocks and is now found in Japan only.

These stones are available in 500 to 10,000 grit. Synthetic Water stones are man-made and are available in grit sizes ranging from 120- 30,000. But these stones wear off quickly.

3.Diamond Sharpening Stones

A diamond sharpener is the most popular type of whetstone used nowadays. These stones are made of human-made diamond particles embedded on an electric plate.

These stones are highly durable, quick in performance, and produce sharp edges. Moreover, these stones undergo minimum wear upon regular use and require little maintenance.

But good quality Diamond stones are expensive, although cheap diamond stones are also available in the market their quality is not reliable.

Diamond Sharpening Stone Vs Whetstone 

Regular sharpening stones are also known as whetstones are popular among knife users overages, these whetstones are available in both synthetic and natural forms with a wide range of grit sizes.

Best diamond stones are expensive but durable enough to last for 2 to 4 years. Well, the choice merely depends upon the type of blade that you are going to sharp.

Diamond stones work well with stainless steel, but for high carbon steel traditional stones are always recommended. Furthermore, diamond stones are not messy to work along.

For a traditional whetstone, you need to keep up the lubrication normally of water or oil, so that the stone grit doesn’t get block, this all makes the process messy.

On contrary, diamond stones are easy to carry, smaller in size, and the grit doesn’t clog, and even if it gets clogged it is easy to clean it up.

Talking about price, many diamond sharpening blocks are available at a low price but these stones are not durable and usually fail to produce sharp edges. A fine grit diamond stone is relatively much higher in price but is highly reliable and durable.

Thus to conclude it all, diamond stones are easy to carry, easy to clean up, durable but a bit expensive, while the traditional whetstones are messy to work along, hard to clean, and get clogged if not maintained properly.

Hence, knife sharpening is an art, and one masters it by practice and experience. But whatever sharpening stone you own, take care not to be aggressive or put pressure on the blade when sharpening.

Most people assume that putting pressure on the blade while sharpening will produce a shaped edge but it is not the case, you will end up with a blunt blade instead.

Understand the alloys and knife material first, then check if the blade is wide, narrow, long, or small, now determine the best angle and stone to start sharpening. If you master the proper technique then every whetstone will become easy for you to use.

They can be both mono-crystalline or polycrystalline and are categorized as continuous or non-continuous diamond sharpening stones. Furthermore below is a complete list of features that you should look upon before making any purchase decision.

2.Diamond hone stone

To hone a stone means to maintain its edge. Honing is a process in which your knife will not get sharp but only its edge will be maintained.

It is because sharpening requires the removal of the upper particle layer of the metal to get the crispy one lying beneath. But honing will only push the metal articles to maintain their alignment.

Traditional honing rods or diamond hone stone serve this job best but these rods are not meant for sharpening the blade.

3.Diamond stone grits

Grit defines the coarseness of stone particles. The higher the coarseness the sharper the blade will be. That is why fine sharpening stones are highly coarse that makes them capable to remove tiny particles above the metal and make it crispy shiny.

Diamond Whetstones are available in different grit sizes ranging from 120- 10,000 coarse sizes. These stones are categorized as the best fine and medium sharpening stones according to their grid size. You should prefer fine-grit ranging 600-1000 and above to own a durable and reliable stone.

4.Diamond Sharpening Block Size

All the sharpening stones have flat surfaces. Their size is crucial in lieu of safety. The larger the surface area of the stone the safer the stone is to work along.

Diamond Sharpening stones are found in continuous and non-continuous diamond surfaces of about 3 inches and 12-8 inches width. 12 inches block provides more surface area to the blade.

These names are given according to their hole sizes. Both are found in mono-crystalline and polycrystalline forms. The stone coarseness is another size factor to consider and is discussed above in detail.

5.Material of the Diamond Sharpening Stone

The material of the sharpening stone determines its longevity and performance. High grid stones are hard and produce eminently sharped blades like Norton diamond stones. These hard small diamond sharpening stones retain their shapes and the surface, making them more durable.

Many soft materials sharpening stones are also available in the market like quad diamond sharpening stones but these stones deform quickly but you don’t need to work for long as these stones are meant to sharpen the knife quickly.

6.Understand your Knife Material

It is very important to understand your knife material and its current sharpness before deciding which stone you are going to purchase. Your knife could be of any following materials:

• Ceramic Blade
• Carbon steel
• Stainless Steel
• Titanium Blades

The harder the blade is the finer the grit you need to make it sharp or vice versa. But most of the sharpening stones do sharp the blade but do not give any finishing touch.

Finest grits produce both the sharpness and razor finish but such finer ones are too expensive to afford. That is why it is recommended to buy a two-sided Sharpening stone with different coarseness at both sides.
