Buying Guides

You should use grit stone for knife sharpening

1. Definition

“Whetstone” is simply another word for “grinding stone”. Sometimes people called it waterstone (for the Japanese versions). The word “whet” actually means “sharpen (knife or other type of tool)”. It has nothing to do with water, or getting wet. This confused me at first.

The history of the use of whetstones in Japan is extensive. Grinding stones have been mined and processed for centuries. It is essential for military purposes (i.e. sharpening swords). 

Thanks to the historical importance of whetstones, the Japanese were able to develop excellent sharpening and sharpening techniques over time. This tradition continues to this day as Japan consistently produces some of the finest handmade kitchen knives in the world.

2. Natural whetstone – Japanese and Western

The original grindstone is found naturally and quarried in many parts of the world. Some popular areas include Arkansas, USA, regions of Europe. And different regions in Japan. Depending on the location, grinding wheels are made from different types of stones.

In the West, the most common stone used as a sharpening stone is called Novaculite. It is also sometimes referred to as Arkansas rock. The most famous area for Novaculite mining is in Arkansas. 

Novaculite sharpening stones are usually quite hard and will last a very long time. Some people pass down their Arkansas stones for generations. These grinding wheels are usually used with oil for lubrication. The main disadvantage of natural Novaculite is that they cut more slowly.

In contrast, the most common Japanese whetstones are made from sedimentary rock. The resulting whetstone is softer and wears out faster than your typical Novaculite. 

The advantage is that they cut better, which means they will sharpen the knife faster. Japanese whetstones are also only used with water. Hence they are sometimes referred to as natural Japanese waterstones.

There are currently no grinding quarries operating in Japan. The most famous mining area is located just north of Kyoto, but it closed in 1967. As a result, Japanese natural sharpening stones are difficult to find and often very expensive. They are usually only used on these days for special or ceremonial purposes (i.e. sword sharpening).

Grit whetstone can be either natural stones or synthetic stones

3. Synthetic whetstone

Nowadays, most people use synthetic/man-made sharpening stones. They offer better sturdiness than natural stone, and are cheaper/easier to obtain. And generally cut faster than natural stone. 

Synthetic stone is made from a bonded abrasive. For example, an abrasive material (usually aluminum oxide or silicon carbide) bonded together with a clay/resin/glass binder. And shaped into a grade level. They can be further classified into oil, water and diamond plates.

Oil stones

Oil stones are so called because they are lubricated with oil prior to the grinding process. They are traditionally used more often in Western cultures. Novaculite (mentioned above) is a natural oil stone. 

Some synthetic stones are specially formulated for use with oil (e.g. Indian Stone), while others can be used with oil or water. It is important to note that once you use the oil on the stone, you must never use it with water, as it will be ineffective.

Water stones

Water stones are lubricated with water before grinding. This is a traditional process in Japan, where both natural and synthetic stones are used only with water. Therefore, many people refer to the Japanese grindstone as the Japanese water stone. 

Nowadays, many Western brands are also producing synthetic water ice. They are the more popular choice because the water is cleaner/easier to use. They are also readily available. Waterstones grind faster, but also wear faster than oilstones. 

As a result, they tend to require more frequent flattening/maintenance. Remember, never use oil on your waterstone!

Diamond plates

You will also find diamond grinding plates on the market. They are basically steel plates coated in small diamond pieces. Diamond is the hardest mineral on Earth. It can therefore be useful for sharpening anything. 

These panels last a long time, but are also often more expensive. Diamond plate does not need oil or water. They can be used directly to sharpen knives or other tools. although it is not recommended for beginners. They are also commonly used to repair (i.e. smooth) water stones that have become uneven after prolonged use.

There are different grit types

4. Grit type

There are different types of grit stones depending on their grinding range and they are all used for different purposes.

For example, if you want to sharpen a knife with chipped edges, you will need less than 1000 grit. Furthermore, to fix a dull knife, you should go from 1000 to 3000 grit. And, 4000 to 8000 grit is used to refine the edge of a knife, which is the finishing process. Finally, if you are sharpening a knife used to cut meat, you should choose the 4000 to 6000 rounds.

Honing experience is important when choosing a sharpening stone. If you’re just starting out or just use a grit stone occasionally, you’re better off with a combination of 1000 to 6000 grit. The combination of these two will do the job for many years.

On the other hand, if you are familiar with grinding and using a sharpening stone and have reasonable experience. You should choose a finishing stone of 8000 grit. So, in general, a person needs at least three stones for different purposes: grinding, sharpening and refining.

Less than 1000 grit: Coarse stones

With numbers less than 1000 grit mainly used for damaged knives. If your blade has any cracks or crumbs in the blade, these stones will remove them for you immediately.

The dual stones above come with a rough side for fixing holes and chips and a medium face for general grinding.

If your knives have also lost all their edges, these stones will also get back to you. These sharpening stones are great for damaged or extremely dull knives, but due to their abrasive nature they should not be used for general sharpening as they do not leave the best finish on the blade. your knife.

Between 1000 and 3000 grit: Medium stones

A 1000 grit is considered your basic sharpening stone. If your knife has lost its sharpness and needs a good sharpening, this is how you should start.

You should not use this stone often, as it will wear out your knife. 2000 and 3000 grit stones can be used more often if you are someone who likes to sharpen a little more often as they are less coarse. 

But again, they are designed for sharpening and not maintaining an angle. Once you get into the habit, you’ll know how often you need to use your average stone.

Between 4000 and 8000 grit: Finishing stones

Now that your #4000 and #5000 stones are like a bridge between your polished and ultra-fine stones. The latter gives you a super delicate edge.

However, you can actually use these stones as the finishing stone of your choice. And perhaps for Western knives there is usually a blade that resembles a ‘U’ shape rather than a ‘V’ edge. The #000 grit can be just as far. But if you want to find 6000 or 8000 super fine stones go for it!

The only piece of advice you should follow is this: If you’re using a knife to cut meat, then you can happily stop at 4000 or 6000. If you’re only using it for vegetables or fruit, switch to 8000. This is due to the refinement you get from 8000 grit. 

With its extremely small grain size, the 8000 grit stone is perfect for final polishing of chamfers and backs. It creates a razor-sharp edge for any tool of the blade.

Frequently Asked Questions

1. How do you talk about the durability of a whetstone?

Follow the feeling. If you can really feel the grains of the stone it’s a grindstone intended only for re-sharpening edges or on extremely dull blades. A moderate grit feels almost smooth to the touch and is used as a primary general purpose sharpener. A fine grit will feel almost as smooth as glass.

2. Is 1000 grit grinding stone enough?

A 1000 grit wet stone will be good enough for most ‘typical’ household kitchen knives. Finer sharpeners will be used less often but will be useful for getting super smooth edges, such as on a fillet knife.
