History: Chopsticks were invented in ancient China before the Shang dynasty (1766-1122 BCE) and most likely much earlier prior to establishment of the Xia dynasty sometime around 9000 years ago. The first chopsticks were probably used for cooking, stirring the fire, serving or seizing bits of food, and not as eating utensils. Chopsticks began to be used as eating utensils during the Han dynasty. Chopsticks were considered more lacquerware-friendly than other sharp eating utensils. It was not until the Ming dynasty that chopsticks came into normal use for both serving and eating. They then acquired the name kuaizi and the present shape.About Us: We are professional kitchen-tool supplier for more than 12 years, our products include wooden chopsticks, bamboo chopsticks, fiberglass chopsticks, stainless-steel chopsticks, measuring spoons and other kitchen supplies, exported to Japan, South Korea, Europe and the United States.
