When purchasing a whetstone knife sharpener, there are things to consider.
Some of the most important ones are the following.
Whetstones come in different grits, and they all have specific uses.
For a normal household owner, they would just pick whatever whetstone they find in the supermarket.
As long as it can sharpen the knife, it’s good enough.
For professionals and home cooks, the whetstone's quality is just as important as the knife's quality.
If you failed to choose or use the right grit for your knife, you would end up damaging it or reducing its lifespan.
Here are some of the things you need to know about whetstone grits and how to use them properly.
Different Whetstone Grits
Coarse stones are often used to repair damaged knives since they have around 1000 grit and below.
If the knives have chips or are extremely dull, this is a good choice since it can help create edges to the knife.
Coarse stones are not advisable for normal sharpening because of their abrasiveness.
They are too rough that they would literally damage a normal knife.
Medium stones have around 1000 grit up to 3000 grit. This is a perfect choice if your knife suddenly lost its sharpness.
This is also the common type of stone used in normal households.
However, you have to remember that medium stones with 1000 grit can wear down the knife if you use it regularly.
As such, if you should only use this when your knife is starting to get dull.
If you want to use the whetstone regularly, you should get between 2000 and 3000 grit.
That's because they are less abrasive.
They would at least lengthen the lifespan of your knives if you are always sharpening them.
Finishing stones usually have between 4000 and 8000 grit. If you will go for the 4000 and 5000 grit, it is the boundary of sharpening stones.
This would provide a more refined edge to your knives.
If you use your knife for meat, you should only go between 4000 and 6000 grit.
If you only use it for cutting vegetables and fruits, you can go up to 8000 grit or more.
Using the correct grade whetstone and learning how to sharpen your knife properly are only the basics if you want to maintain your sharpening tool.
You need to make sure the whetstone is easy to maintain because maintenance would help the product last for a long time.
How To Care for Whetstones
Choose the Correct Angle
Never sharpen your tools using a low angle because you will only remove more metal from your knife to get the edge you want.
You also lower the stone's lifespan since you are putting more wear and tear on the surface.
This would be a trial error, so make sure that you start with a higher angle.
If you are unsuccessful, bring the angle down a bit and start sharpening again.
Don’t Use Your Whetstones on Bulky Tools
Although most products claim that they can sharpen bulky tools like axes, machetes, and more, it doesn’t mean that you can just sharpen them directly.
The first thing to do is to work them on a belt grinder.
Once the damaged outer edge is already removed, you can use the whetstone to sharpen them.
It means that if you plan to sharpen a knife or a bulky tool that would require the removal of metal, you need to find an alternative way to remove it before using a whetstone for the finishing.
Level Your Whetstones Before Using
One of the most common homeowners' mistakes is that they usually place the whetstones anywhere on the table or countertop without checking if it is labeled.
Put the ruler across the cutting surface of the stone and hold them up to the light.
If you see any space between them, it means that you need to level the stone.
Normally, whetstones would wear faster in the center because most people will use the center to sharpen their knives.
However, this would also mean that if the center starts to recede and the sides remain untouched, the stone will be unusable in just a few years.
Keep It Lubricated
Some whetstones are ready to use even without wetting it, while others will only require a splash of water before using it.
For that latter, the most important thing to do to make sure that your whetstone will last for a long time is to apply the right amount of water.
If the whetstone is properly lubricated, the material will not recede faster.
Even if you are already close to the end of your sharpening session, you still need to check if the whetstone is still wet or dry.
Always reapply water if necessary.
Sharpening stones come in several surface widths and heights.
The larger and wider the blade is, the larger and wider the whetstone should be to ensure the blade is sharpened without missing a spot.
If you've a lot of knives of different sizes that you use regularly, it is better to purchase a set.
Sharpening Stone FAQs
1. How To Use a Whetstone
Using a whetstone is not as simple as grinding the blade of your knife on the surface.
Some people do that, but if you want your whetstone and your knife to last for a long time, you should know how to use a whetstone properly.
Keep Your Whetstone Wet
Although it is fine to just grind the knife directly without wetting the whetstone, it is not advisable since it may damage the knife.
Before using a whetstone, you need to submerge it in water for about five to 10 minutes.
Some people would prefer to let the whetstone soak in water for a minimum of 24 hours before they use it.
There are also new whetstones that won’t require you to soak it in water.
Just keeping the whetstone wet is good enough.
Keep It Steady
After saturating the whetstone, the next step is to get a mat or towel.
You can also get the included holder of your whetstone.
These items would prevent the sharpener from sliding while you're sharpening the knife, especially when fully soaked in water.
Ensure that you apply water from time to time and never allow the whetstone to become dry while using it.
Grind the Knife
Most whetstones have a coarse and fine side.
Before you start sharpening, the first thing to do is to use the whetstone's coarse side.
Next, you should hold the blade at an angle ranging from 15 or 20 degrees.
You have to maintain this angle throughout the process and make sure that you move the blade back and forth across the whole stone.
Once you are done, wipe off the blade and the corner of the stone to remove some of the burrs remaining and turn to the other side of the blade.
After doing both sides, flip the whetstone and use the fine side for the finishing.
2. What are Japanese whetstones made of?
All types of whetstones can either be natural or synthetic.
Most Japanese water stones are natural stones and valued for their authenticity and beauty.
They vary in consistency because it would depend on the type of stone used for sharpening.
Japanese whetstones are also synthetic and are made from aluminum oxide, silicon carbide, or a diamond coating placed on a metal sheet.
3. What grit sharpening stone should I get?
It would depend on how you plan to use the whetstones.
In normal households, they only have a single whetstone with a coarse and fine side.
As for home cooks and restaurants, they usually have a stone with a low grit of 200 to 400 for damage repair, a middle grit about 1000 for sharpening, and a high-grit stone with 3000 or above granularity for a final polish.
4. How long should you soak a whetstone?
Most of the newer models of whetstones don’t require you to soak the stone for a long time.
The common whetstones have to be soaked at least five to 10 minutes before using them.
5. Can you over soak a whetstone?
Soaking it for 24 hours or even more won’t be a bad idea and will not negatively affect the whetstone.
You can soak it for days if you want. Just make sure you dry it completely if you store it.
That's because molds may develop on the surface of the whetstone.
6. Is 1000 grit whetstone enough?
In a typical home kitchen, a 1000 grit whetstone is already good enough to polish your knives.
Since you are not chopping anything that would damage your knife's blade, you don’t need to get any coarser whetstones.
On the contrary, for most restaurants and people who love to cook, this is just the basic requirement for a whetstone.
They usually get different types of grits to help them deal with different situations when they are cooking.
Looking for the best Japanese whetstone is not too much of a problem.
That's because there are so many innovative products that you can find in the market.
Choosing a whetstone would depend on how you plan to use it.
