Blades are generally rugged and cut well, but over time there is bound to be a degree of wear and tear associated with several key factors.

Production material

Blade material is made of hard wear resistance, but at the same time, the lower the toughness. Hardness is the opposite of toughness, and this is an area that needs improvement. If it is graphite blade, the material can choose a better toughness.

The surface coating

Diamond coated blade has the advantages of high hardness, good wear resistance, low friction coefficient and so on. However, the production cost is high, and the domestic technology is not mature enough. Graphite coated blade is widely used and practical.

Therefore, if you want to reduce the wear strength of the blade, you can give priority to the material and coating.
