After long use in the kitchen, any knife needs sharpening. To do this quickly, many resort to using a special grinding wheel, which is driven by an electric motor. In the absence of it, the most desperate try to grind knives with a file and even sandpaper. But few know how to sharpen knives correctly.
This process is simple, but rather painstaking, requires perseverance and a little knack that comes with experience. Before
sharpening knives correctly with a bar, it is necessary to correctly select the bars. In total, you will need two bars for sharpening: one is coarse-grained, and the second is fine-grained. In the process, you must constantly keep the knife blade wet. It is best to lubricate it with mineral oil, but in the absence of one at hand, you can use plain water.
Also, before sharpening knives with a stone, look for a piece of leather. In this case, you can use the old belt. More precisely, you only need its back side, which is not processed and resembles suede.
Sharpening angle selection
Before you get down to business, you need to determine at what angle we will sharpen the knife. The range is quite wide and ranges from 15 to 45 degrees. The choice is made depending on the quality of the steel of which the knife is made, and on what purpose it will be used in the future.
It is also necessary to consider the following feature. The smaller the angle at which you sharpen the knife, the faster it becomes dull. This can be explained by the fact that the edge of a sharp knife is quickly rounded, or, even worse, crumbles.
How to constantly maintain the same angle?
Now let's figure out how to sharpen knives correctly with a bar. To begin, place the bar on the table and fix it motionless. Then position the blade of the knife in relation to the bar at the angle you need. Move the blade along the bar in only one direction, for example away from you, trying to maintain a given angle. Immediately it can be noted that this is difficult. Therefore, it is better not to rush, but to do everything smoothly.
Inexperienced can give such advice. Make a blade from a wooden block , the angle of which would correspond to the required sharpening angle. Put the blade on a wooden wedge and move the knife along the bar with it.
Sharpening
First you need to take a bar with large grain. Moisten it with water or oil before use, as mentioned above. Sharpen the blade until the so-called burr along the entire length. In order to determine its presence, simply swipe your fingernail on the back side, which was not sharpened, from the butt to the edge. Also sharpen from the back, after which the burr should bend to the other side. Repeat with fine-grained bar. After that, the burr will become a little smaller.
The third time, repeat the manipulation of the bar, which has a fine grain. As a result, the burr will decrease further. To completely get rid of it, use the skin from the back.
Thus, after reading this article, you already know how to sharpen knives correctly with a bar. However, there are many more ways to sharpen a knife. It can be special sharpeners that are sold in any underground passage. But the better to sharpen knives, a person understands only with experience, having tried a whole arsenal of devices.
