The kitchen knife is an indispensable tool in everyone’s kitchen life, but it will become dull after being used for a long time, which brings great inconvenience to everyone. Today, I will introduce several methods for sharpening knives to save time and effort.
Whetstones are a common tool for sharpening knives, but this method can be difficult to master. First, sharpen the inner edges. When sharpening the knife, make sure that the angle between the blade surface and the whetstone is 3-5 degrees, so that the sharpening can save energy when cutting vegetables. Then, slowly sand the outer edges. At this time, the angle between the kitchen knife and the grinding stone should be kept small to separate the cut vegetables from the kitchen knife, saving time and effort.
If there is no grinding stone, porcelain can be used instead, such as porcelain cups, bowls, etc. First, turn the porcelain upside down and grind it with a knife that has tiny rough particles on the bottom. Next, we can sharpen the knife. We should stabilize the knife handle so that the angle between the knife surface and the bottom of the cup is about 20 degrees. The knife can be sharpened more than ten times. Because the bottom of the porcelain is very rough and hard, close to the grindstone, the grinding of the blade surface and the porcelain bottom will produce friction, making the knife sharper.
Similarly, sandpaper can also be used to sharpen knives. You can make a makeshift grinding rod by wrapping a cylindrical object such as a roller needle in sandpaper. The polishing method is similar to that of porcelain, which is at an angle of 20 degrees. The sandpaper can also be ground on a table or cutting board, making it easier to fix the sandpaper. Sand the sandpaper repeatedly at an angle of 20 degrees, taking care to keep the strength stable.
The above three methods are actually good ways to sharpen the knife, but you must remember to wash the knife after sharpening it, so that it will be sharper next time. However, it is best to keep a whetstone at home so that it does not damage other instruments.
