All knives, even in the manufacture of which high-quality steel or such material as ceramics were used, begin to dull after prolonged use. There are several different methods that allow you to sharpen blades with a dull blade. Some users, in order to achieve the most effective result, use the so-called water stone to sharpen the knife.
What is a water stone
The water stone is a special, powerful and versatile sharpener. It has different grain sizes, thanks to which, alternating large and small grains when sharpening the blade, you can achieve maximum sharpness. However, these stones are not suitable for so-called dry work. Before use, they must be soaked in clean water. It is thanks to this feature of the application that such grinding wheels are called water.
After being placed in a container with water, it gradually begins to fill the pores of the sharpener, and additionally plays the role of a lubricant during the work of sharpening the blade. It should be noted that such a stone is perfect not only for sharpening knives, but also (due to different grain sizes) it is used in cases where it is necessary to correct damage to the surface of the blade, to polish or straighten the cut edges.
To indicate the granularity of water stones, a special numerical scale is used. As a rule, sharpeners are used for simple and ordinary sharpening of a knife, the grit of which varies between 600 and 2000. However, an abrasive with a grit of 80 to 400 is used to straighten and restore a badly worn blade . that shows signs of damage.
How to sharpen knives on a waterstone
Immediately before use, the water stone should be placed in a container filled with water and kept there for about 15 minutes. It should be noted that the grinding wheel should be in water until the air bubbles stop coming out of it.
Then you need to take a stone and place it on a special stand and securely fix it on a flat surface, for example, on a table. To prevent the backing from slipping, you can place it on the fabric. After completing the preparatory procedures, you can begin to sharpen the knife. To do this, you need to take a knife and hold it with both hands, at a certain angle (about 45 degrees to the axis of the whetstone), gently pull the cutting edge along the surface of the grinding wheel. It should be noted that the procedure for sharpening knives begins with the coarse grit side of the waterstone.
During sharpening, the stone must be periodically moistened with water. It should be noted that when working on its surface, a small accumulation of dirt may form. It should be said right away that this is a normal phenomenon, and the dirt that appears at first glance is an ordinary emulsion, which consists of an abrasive and pure water.
When sharpening, you need to constantly monitor the sharpness of the sharpening knife. If the burrs stopped appearing during sharpening and all flaws in the blade were removed with a coarse grit, then you can use the other side of the bar with a finer grit and complete the sharpening process. sharpening.
It is not recommended to sharpen (sharpen) the blade using a variety of electric sharpeners with high-speed grinding wheels. This is due to the fact that at high speeds the blade material begins to heat up strongly. As a result of such heating, an uncontrolled release of the blade or the so-called cutting edge may occur.
When sharpening a blade with a sharpener, the user must set a single, consistent angle. In this case, it is important not to use force when performing work, but to be vigilant and attentive. It is very important that the abrasive material meets the sharpened blade at a constant and identical angle.
