Having a set of blunt kitchen knives is not only inconvenient, but also very dangerous. A blunt blade requires more pressure to cut the food. The more muscles you press on the knife, the more likely it is to slip and hurt you. A good whetstone can keep your blades sharp, making them safer to use. This priceless workshop and kitchen tool can sharpen the edges of knives, scissors, planes, chisels and other cutting tools. The whetstone is actually a hard material, including Japanese ceramics, water stones, and even diamonds. Coarse grindstones can repair dull blades, while fine grindstones can grind sharp edges. Most gemstones have a wide surface area for sharpening and a non-slip base to facilitate the sharpening process.
If you have a set of dull knives that need to be sharpened well, read on to learn more about these powerful whetstones and find out why the following products are one of the best whetstone choices on the market.
There are four basic categories of whetstones: water stone, oil stone, diamond stone and ceramic stone. Read on to learn more about each type and determine the best whetstone for your needs.
Waterstone and some oilstones are made of alumina. The difference is that the water stone is softer, so the cutting speed is faster. Moreover, since this stone uses water to remove metal debris from the stone, it is also cleaner than using oil-based stones. However, because this kind of stone is softer, it wears out faster than other stones, and you need to flatten it regularly to restore the stone.
Whetstone is made of novaculite, alumina or silicon carbide, and oil is used to remove small pieces of metal for sharpening. There are many grades of this type of stone, from fine to coarse. Due to the hardness of the stone, fine edges can be created on tools and knives. Whetstone has the advantages of low price and low maintenance cost. Because they are too hard, they rarely need to be flattened. The disadvantage of whetstones is that they have a lower cutting speed than other types of stones, which means that you need a longer time to sharpen the blade compared to using water or a diamond sharpener. Remember, because you have to buy sharpening oils to use oilstones, using them also involves additional costs and confusion.
The diamond sharpener consists of small diamonds attached to a metal plate. These diamonds are harder than other types of gemstones (in fact, they are sometimes used to flatten softer whetstones), so the blade can be sharpened faster. Diamond grindstones either have a smooth surface, or have small holes for capturing metal chips, and have varying degrees of roughness. Smooth sharpeners can be used to sharpen the edges of tools and knives, whose tips or teeth may get stuck in small holes. Diamond is the most expensive whetstone.
Ceramic stones are highly respected for their durability and ability to form fine edges on knives. When it comes to the level of gravel, these stones provide excellent accuracy and rarely need to be reworked. High-quality ceramic gems tend to be more expensive than other gems.
The grain size or material type of the whetstone largely determines its sharpening effect. Read on to learn about the grit, materials and other considerations you should consider when buying the right product.
The whetstones have different grain sizes. The smaller the number, the thicker the stone, and the higher the gravel level, the finer the stone. The grain size of 120 to 400 is suitable for sharpening very dull tools or tools with chips or burrs. For standard blade sharpening, 700 to 2,000 grit stones work best. The high particle size level of 3,000 or higher creates an ultra-smooth edge with little or no serration on the blade.
The material used in the sharpener has a lot to do with the edge it stays on the knife. Whetstone will leave a more jagged edge on the blade, even if the grit level is higher. Water stone provides a higher level of gravel to obtain a smoother surface instead of sawing. Lower-grained diamonds will leave a rougher surface when cutting soft materials, while higher-grained diamonds will produce finished edges for cutting harder materials. The material of the sharpener also determines the stone’s ability to withstand repeated sharpening. Softer water stones need to be repaired regularly, while harder diamonds do not.
Most whetstones are shaped like blocks and are large enough for most blades. Many have mounting blocks with non-slip bottoms that can secure your block to a table or counter and provide a sturdy base from which you can sand. Some compact sharpeners have slots in which you can place knives or blades. This design makes sharpening easier to manage, but the accuracy is slightly lower because it creates a sharpening angle for you. You only need to slide the tool back and forth in the groove to sharpen the blade. These slotted blocks usually have coarse grooves for blunt edges and fine grooves for finishing.
The sharpener must have enough surface area to grind everything from small knives to large carving knives. Most whetstones are about 7 inches long, 3 inches wide, and 1 inch thick to leave enough surface area to sharpen different types of blades.
These sharpening stones are made of high-quality materials and can grind dull edges into sharp blades without damaging the knife. Our preferred products include products from some of the most well-known whetstone manufacturers.

If you still have questions about whetstones and how to care for them, please continue reading the answers to the most common questions about these tools.
Soak the whetstone in water for five minutes, and then use it for the fine whetstone. Ten minutes should be enough to completely soak the rough stone.
First pass the blade through the stone at an angle of 20 to 25 degrees. Hold the handle of the knife with one hand and the blunt side of the blade with the other hand. Pull the blade towards you while making a sweeping motion on the block. Then flip the blade and make the same movement on the block in the other direction. Make ten strokes on each side, and then test the sharpness of the blade by cutting the edge of a piece of paper. Continue this process until the edges are sharp and the paper can be cut easily.
It depends on the type of whetstone. To clean the oil stone, rub a small amount of oil on the stone in a circular motion. For water stones, use water. This will cause the stone to release the tiny metal particles you grind off the blade from its holes. Rinse the stone with water, then wipe it with a paper towel.
Depending on the type of stone, moisten the stone with oil or water. Use No. 100 sandpaper to remove any inconsistencies until smooth. Then use 400 grit sandpaper to remove any scratches caused by coarse sandpaper. You can also purchase a compression plate specifically designed for this purpose.
