Mainly used for quick sharpening of kitchen knives, scissors, fruit knives, etc. Moreover, it also has the unique function of grinding various special-shaped knives and repairing kitchen knives, which is called a universal knife sharpener.
For household knives, as long as the knife is not blunt, and the sharpness is not sharp enough, just use coarse and fine sharpening. When sharpening the knife at the rough and fine sharpening place, you don’t need to use your hands. Put the knife on it. Just pull back with your own weight. Remember: only pull back, don’t push back and forth. For fine grinding and rough grinding, only sharpen the blade, sharpen the knife at the fine grinding place, the faster you sharpen it
Depending on the material of the knife, only when the knife is blunt, use the cutting edge to open the edge. When cutting the edge, the blade head is slightly lower, and then pull it back straight down slightly;
Remember: when opening the blade, the knife should be laid flat vertically. The blade looks good, and the cheeks on both sides are equally flat; if the blade is crooked hard, the cheeks on both sides of the knife will be large and small on both sides; if it is crooked, it will be sharp. The degree is the same, but the cheeks are not pretty!
