1, ground with a grindstone.
Tools for sharpening knives mainly include grindstones, sharpening sticks and grinders. Sharpen a knife with a whetstone. Choose fine grindstone or fine oilstone. Before sharpening the knife, put the grindstone on the side, sprinkle some water, and then turn the scissors upside down, so it's easier to sharpen. If you can't turn it upside down, you can grind it directly.
The inclined plane of the scissors forms a horizontal angle with the grindstone and grinds it back and forth in the horizontal direction. Pay attention to keep the two scissors blades completely cut. If the blade is worn, the inner plane can be horizontally attached to the grindstone for three or four times. Just grind it for a while.
Step 2 grind with a sharpening stick
In the vegetable market, we can often see the butcher sharpening his knife on a steel pole. This is a sharpening stick. You can grind it back and forth on the sharpening rod along the inclination of the scissors incision. Please be careful not to hurt your hands when grinding.
Step 3 sharpen the knife with a plate
We can use the bottom of the bowl at home to polish the scissors, choose the rough bottom of the bowl, polish it back and forth against the protruding part of the bottom of the bowl according to the inclination of the scissors, and add some water to lubricate it appropriately.
The ground scissors are used to cut ordinary things. If you feel comfortable cutting, it means it is sharpened. If you still feel dull, you need to continue grinding. You can also test with empty scissors. If you can hear the neat shearing sound, it means that the scissors are grinding faster.
