Knives are a versatile tool for many activities and they are sometimes an essential piece of equipment. Just some of the activities for which you may use knives include cooking, camping, hunting, fishing, crafts, and furniture making. While a good knife is a useful item for all these activities, a blunt knife is almost useless and potentially more dangerous than a sharp knife. Blades will gradually become dull and blunt as part of natural wear and tear and they are then less effective. It takes longer to cut, the cut is not as precise, and the knife may slip instead of slicing straight through. Therefore, keeping your knives sharp is essential. Some of the best sharpening tools are Japanese waterstones. Here is a guide for the things to consider when buying Japanese waterstones and reviews of some of the best Japanese waterstones on the market.

Buying Guide- Things to Consider When Buying Japanese Water Stones
You might suspect that all Japanese water stones are the same, but this is not the case. There are several grades, sizes, and options. Therefore, you need to think carefully about what you need the stones for and take each of the features into account. Here are some of the factors you should consider when making your choice.
There are many sizes available, so you should consider the following points:
- If you only need to sharpen small knives, a smaller whetstone will do the job just as well.
- For those who have large knives or knives of multiple sizes, it is better to choose a larger water stone.
- Lager waterstones will usually cost more than smaller waterstones.
The grade of Japanese whetstones refers to the size of the grit particles in the stones. Generally, there are three grades of Japanese whetstone and there is the option to buy stones that have different grits. Your options include:
- Rough- These have the largest grit particles and are graded between 120 and 140 grit.
- Medium- The medium Japanese waterstones are graded between 700 and 3000 grit.
- Smooth- A smooth Japanese water stone will have a grade between 3000 and 10,000. It is worth noting that there is no upper limit to the grading, but you are unlikely to see any significant improvement by using stones with a grade over 10,000 grit.
- Single grit stones- These are the water stones that have only one grade of grit.
- Multi-grit stones- Also called multiple grip stones; these stones have more than one grade of grit. These are usually double-sided with a rougher stone on one side and a smoother grit on the other.
- Sets- You can also buy a Japanese whetstone set. These have three water stones which include a rough, medium, and smooth stone in each set.
Which grade of Japanese whetstones you choose depends on what you want to achieve. The following is a guide for the different uses of the stones:

- Buffing and polishing- Some of the rougher Japanese sharpening water stones can create scratches to the surface of the blade. To get rid of these, you can use the smoother stones to buff and polish the blades.
The price of a product is a significant factor for many people when deciding what to buy. Consider the following:
- The price is affected by the brand, the size of the stones, the grit, the quality, and the location from where the stones were mined.
- Individual single grit stones are usually cheaper than multi-grit stones and sets of three single grit stones.
- However, buying three individual single grit stones with different grit grades will probably cost you more than buying a multi-grit stone or a set of stones.
- There are cheap starter sets available and expensive sets intended for professional use.

How to Sharpen Knives Using Japanese Waterstones
Sharpening knives using Japanese waterstones is surprisingly easy, although it can take some practice to master the technique. Here is a quick and easy guide for how to use Japanese waterstones to sharpen your knives.
- Prepare the stones- Before using the stones, soak them in water for approximately ten minutes first until there the stone has soaked up plenty of water and a film has developed over the stone. You should do this to all the stones you plan to use.
- Splashing- After removing the stones from the water, splash them with a little more water.
- Position the stone- If the stone comes with a holder, set up the stone in this. Otherwise, simply place the stone perpendicular to your body on a damp tea towel.
- Holding the knife- Using your dominant hand, hold the knife at a 45-degree angle across the stone. The edge should face you and the hell of the knife should point towards your abdomen.
- Adjusting the angle- Now, you need to adjust the angle for sharpening and it can take practice to get the angle right. For Japanese knives, the right angle is about 12 to 15-degrees. To get this angle, put your index finger between the spine of the knife and the stone and remove your finger before sharpening. Western knives need a slightly higher angle of around 20-degrees. To set the angle using your index finger and then raise the spine of the knife slightly.
- Apply pressure- Using your non-dominant hand; apply some pressure to the belly of the knife.
- Start at the tip- Putting the tip of the blade against the stone, move it backward and forward along the stone around five times. Repeat the process on the middle section of the knife, again moving the knife five strokes up and down the stone.
- Flip the knife- You should then repeat the process on the other side of the knife. However, you should lead with the heel this time rather than the blade.
- Check the burr- You should aim to create a burr. This is when there is one scratchy and one smooth side to the blade.
- Removing the burr- To remove the burr, you should use a leather strop. Draw the knife blade over the leather strop in a motion that is similar to sharpening the blade. You can do this with a fibrous tea towel if you do not have a leather strop.
- Testing the sharpness- When you have removed the burr, you can test the sharpness of the knife with a piece of newspaper. Holding the newspaper at an angle of around 45-degrees, carefully slash the paper with the tip of the blade. If the knife is sharp enough, it should cut easily.
- Switch stones- If your knife is sharp, you are ready to switch stones and start using the smooth stone. Or, if you are using a multi-grit stone, turn it over to use the other side. If it has become dried out, splash with a little more water.
- Polishing- Using the smooth stone, you can now polish and buff the knife. You should use the same technique as for sharpening but apply less pressure. Approximately 30 strokes on each side should polish your blade nicely.
- Wipe clean- Using the leather strop or a tea towel, wipe your blade clean.
