Chopsticks are shaped pairs of equal length sticks used as the traditional eating utensils of various East Asian countries. Chopsticks originated in ancient China, and are now used in China, Japan, Korea, Malaysia, Indonesia and Vietnam. They can also be found in some areas of Tibet and Nepal that are close to Han Chinese populations. Chopsticks are smoothed and frequently tapered, and are commonly made of bamboo, plastic, wood, or stainless steel. They are less commonly made from porcelain,silver, ivory or jade. Chopsticks are held in the dominant hand, between the thumb and fingers, and used to pick up pieces of food.
