The Mong people often use scrap iron and steel such as automobile leaf springs, springs, and construction steel as the main raw materials. They choose the appropriate type of steel for each type of agricultural tool to ensure flexibility, durability, and sharpness. The steel tempering technique is passed down from generation to generation, based on each family's own experience and secrets. Forging not only creates production tools but also demonstrates the Mong people's ingenuity, creativity, and self-reliance. It contributes to maintaining and promoting the national cultural identity.
