Chopsticks have a history of over 3,000 years originating in China in the 11th century BC. They are commonly made from wood, bamboo, jade, ivory, plastic, or metal, and are typically held between the thumb and first two fingers, using one stick to maneuver food while the other provides stability. Proper chopstick technique involves gripping them in the middle of the thumb and index finger with the bottom resting on the ring finger.
