Sharpening a knife with a whetstone is one of the most effective ways to bring the blade to razor-sharp precision. This traditional technique is valued by both professional and home cooks as it offers full control over the sharpening process and extends the life of the knife. In this blog post, you will learn the basics of sharpening with whetstones, from proper preparation to technique and care.
1. Why a whetstone is the best choice
A whetstone offers many advantages compared to other sharpening methods such as electric sharpeners or grinding rods:- Control : You have full control over the angle and pressure, which is especially important to maintain the optimal sharpening angle of your knife.
- Durability : Due to the gentle processing of the blade, material loss is kept to a minimum, which increases the lifespan of the knife.
- Versatility : Sharpening stones are suitable for all types of knives, from Japanese and Damascus knives to classic kitchen knives.
2. The right choice of whetstone
Whetstones are available in different grits that determine the degree of abrasion. Choosing the right grit depends on how blunt your knife is and how finely you want to sharpen the blade:- Coarse (200-600 grit) : Ideal for quickly sharpening very blunt or damaged knives and getting them back into shape.
- Medium (800-2000 grit) : Perfect for the regular sharpening process to keep the blade sharp and remove small imperfections.
-
Fine (3000-8000 grit) : This grit is used for the final polishing to bring the blade to maximum sharpness and make it razor sharp.

3. Preparation of the grindstone
Before you start sharpening, you should prepare the whetstone to achieve optimal results:- Soaking : Most whetstones need to be soaked in water for about 10-15 minutes before use until no more air bubbles rise. This ensures that the surface of the stone is lubricated and prevents the blade from overheating during sharpening.
- Stable surface : Place the whetstone on a non-slip surface or a special whetstone holder to ensure that it does not slip during sharpening.
4. The correct sharpening technique
The key to a sharp blade is technique. Here are the basic steps to effectively sharpen your knife with a whetstone:- Sharpening angle : Hold the knife at an angle of about 15-20 degrees to the whetstone (10-15 degrees is optimal for Japanese knives). This angle provides the ideal balance between sharpness and durability of the blade.
- Movement : Slide the knife across the whetstone in a smooth motion, from the heel to the tip of the blade. Apply light pressure and draw the blade across the stone in an arc to evenly sharpen the entire edge.
- Switch sides : Repeat the process on the other side of the blade to ensure both sides are sharpened evenly.
- Finer Grit : Once you have finished the coarse grit, switch to a finer grit to polish the blade and give it the finishing touch. (If you have one, you can use a special leather strop with polishing paste and polish the knife with it.)
5. Checking the sharpness
After sharpening the knife, check the sharpness with a simple test:- Paper test : Cut a sheet of paper; a sharp blade should slide through the paper effortlessly.
- Tomato test : Try to cut a tomato without applying pressure; a sharp blade should cut through the skin immediately.
6. Care of the whetstone and blade
-
Cleaning : After sharpening, the whetstone should be thoroughly rinsed with water and dried to remove any deposits.
-
Correction : Over time, the whetstone may become uneven, so use a honing stone or a surface grinder to straighten the surface of the stone.
-
Knife care : After sharpening, clean the blade thoroughly and dry it to prevent rust. Store the knife in a safe place such as a knife block or magnetic knife holder.
Conclusion: The art of sharpening with whetstones
Sharpening with a whetstone may take some practice at first, but it is the most effective way to keep your knives sharp for longer. The combination of control, precision and care that a whetstone offers makes it the best choice for anyone who wants to maintain their knives to the highest standard. With the right whetstone and the right technique, you can restore your knives to a new, razor-sharp quality and significantly extend their lifespan.Since this is a very large (and important!) topic, I would like to point out that this blog post does not cover all the special features; it can only give a rough insight into the topic of sharpening.
