There are actually several types of chopsticks. Japanese chopsticks are pointed, while Chinese chopsticks have blunt ends. Typically, Chinese chopsticks are the longest and made of bamboo.
Korean chopsticks are medium in size and made of a silver material.
There are chopsticks used specifically for cooking and some for eating. Each person has their own set of chopsticks that are kept in a box. Hold the lower half of the stick firmly against your ring finger. Hold the second chopstick as you would hold a pencil. To work the chopsticks, keep the first stick stationary.
