Problems solved by technology

At present, knife sharpeners can be divided into two types: electric knife sharpeners and manual knife sharpeners according to the way of use: electric knife sharpeners and manual knife sharpeners. Electric knife sharpeners are appliances that use electricity to drive the motor to sharpen knives. During the use of the knife sharpener, a large amount of material will be lost, it is not suitable for sharpening the blade thin, and the cost is high

The manual sharpener is done manually, but it is generally double-sided grinding when used, which is easy to damage the blade and makes the sharpness of the blade very short. It is also not suitable for grinding the blade thin.
