Hello All! We recently posted a short article on our blog about this. Here is the condensed version!
The impact chopsticks have made on society is impressive. Most scholars agree that they were probably used first as cooking utensils in China as early as the Shang Dynasty. As the population expanded, resources became scarce and people tried to cook their food more quickly to save fuel. To do this, they would cut and cook their food in smaller pieces, which also made it suitable for eating with chopsticks. As they grew in popularity throughout China, they began to morph into shorter, more usable shapes that were better suited for eating.
By 500 A.D. chopsticks had spread from China to Korea, Vietnam and Japan. Each region developed unique styles of chopsticks that were best suited to their own unique foods and cultures. In Japan, they lacquer their chopsticks with beautiful designs as a reflection of their highly artistic culture. By the end of the Ming Dynasty, chopsticks were mainstream throughout most of Asia.
Chopsticks are actually chinese, and they are made of bamboo, reason being is bamboo grows quickly, is virtually free and been around for many thousands of years. Metal is a rather new invention and expensive compared to bamboo.
