The base material is made of special hard spring steel and undergoes a unique heat treatment process, giving it enhanced toughness and making it less prone to breaking or bending.

As shown in the picture, the blade is coated with an alloy overlay, increasing its wear resistance by 3 to 5 times compared to the original base material. Due to the different wear resistance between the base material and the alloy, the blade becomes sharper, resulting in better soil penetration and improved cutting performance.
