Kitchen knife sharpening stone
There is no such knife that stays sharp forever. Even the best knife in the world will lose its edges depending on the quality and frequency of use. Each time you use your knife it will get dull and lose some of its sharpness. Proper maintenance and sharpening are the two main factors that affect the longevity and performance of a knife.
A dull knife is more dangerous than a sharp one. This is because a dull knife needs more force than a sharp one to cut through meat and vegetables. If you are not an expert in sharpening a knife you can send it to the store or visit a professional to get the job done. Sending the knife to a professional will be time-consuming and costly. The best way to sharpen a knife is to get a quality sharpening stone, aka whetstone, and do it yourself. A knife sharping stone works by removing small bits of metals along the edge of the blade and leaving a new sharp edge behind.
This is a fact that a good quality knife sharpening stone will help to enjoy razor-sharp edges but that will need some sort of sharpening skills. Every knife is different than the other and it required special treatment to be sharpened. A manual, boxed with the sharpening stone, is the best source to learn how to sharpen a knife using a sharpening stone. There are many videos available with proper knife sharping demonstrations on YouTube and the internet. Here is one of them.
What to look for in kitchen knife sharpening stone?
There are different kinds of sharpening stones available in the market. Some of them with different grit sizes and others are made of different materials such as oil stones and water stones. The selection of sharpening stones depends on the knife blade material and blade thickness. Every knife needs special treatment and a different sharpening angle. Following are some of the main features of a knife sharpening stone to consider.
Sharpening Stone Grit
Grit values define the fineness and coarseness of the sharpening stone surface. The higher the git number the finer sharpening stone surface. Coarse grit is used for rough blade edges and finer is used to hone the knives. A grit below 1000 is effective for a blunt or damaged blade, above 1000 and below 4000 for sharpening dull knife blades, and a grit value above 4000 for honing razor-sharp edges. The grit between 4000 and 8000 are used as polishing stones rather than sharpening stones.
To have a perfect shape blade and razor-sharp edges, it is a good practice to use a combination of higher and lower grit stones. A single-faced or one-sided stone comes in just single grit value and double-faced or two-sided sharpening stones with both higher and lower grit. The doubled-faced sharpening stone is coarse with a lower value on one side and finer with high grit on the other side.
The second feature in sharpening stone design to look for is the secure base or handle. A secured-based stone provides precision and the right angle to sharpen the knife, but it needs to be placed on a hard surface. A stone without any base is portable but it is also hard to get the right sharpening angle.
Types of Sharpening Stones
Sharpening stones are available in a variety of materials such as oil stones, water stones, diamond stones, or ceramic stones. Whetstones or sharpening stones with different materials depending on the size and materials of the blade and also the frequency of sharpening.
Oil stones are more durable and harder than water stones, that is why they require less flattening. The oil stones need to be lubricated with oil before processing. The only disadvantage of oil stones is the messy cleanup after every use.
Natural Water Stones
Natural water stones are formed of quartz, such as a novaculite. These stones are mined from stone quarries available in Arkansas, Japan, Syria, and Lebanon. The water stone requires initial soaking in water between 10 to 15 minutes before processing. Water sharpening stones required constant moisture during the process. A stone with 3000 or above grit should not be soaked in water, use a splash of water if required. Water stones are softer than oil stones, easy to clean, and require more flatting.
Synthetic Water Stone
Synthetic or artificial water stones also known as ceramic stones are made artificially from ceramic such as silicon carbide or aluminum oxide. These stones are harder than natural water stones and require less water soaking during the process. Synthetic water stones are easy to clean and require less or no water and oil.
Diamond sharpening stones are the hardest of all, made with industrial diamonds. There are two different types of diamond stones, Polycrystalline and monocrystalline. Monocrystalline diamond sharpening stones are the highest quality, single structure with the longest lifespan. Diamond stones are more expensive than oil and water sharpening stones. They have the highest quality sharpening surface and require very less or no flattening in most cases.

For smoothing the surface of the stone, you will need another stone or sand screen disc with lower grit values. A grit between 100 and 400 is recommended to flatten the surface.

For common household use, the knife sharpening stone will last for about 5-10 years.

Once you get that place the knife on the moisture stone with the right angle and draw the blade down and across the whetstone in an even motion.
