It's unclear when chopsticks were first used, but it's undoubtedly true they were invented in China and their wide use can be traced back as far as 3,000 years ago. The acceptance of Confucianism is believed to have further cemented the use of chopsticks as the primary Chinese eating utensil. According to Confucius, knives - associated with violence, were not to be brought to the dinner table.

    Today, chopsticks are used not only in China, but also in Japan, Korea, and Vietnam, making them the world's second most popular method of conveying food to the mouth.
