Japanese chopsticks are usually shorter than other chopsticks and taper to a fine point. They are traditionally made of bamboo or wood and are often lacquered. Japanese chopsticks also come in kid sizes and woman sizes which are even shorter than standard sizes. Bento sized chopsticks, which fit inside of bento boxes, can also be quite short and sometimes made of colorful plastic.
In Korea, chopsticks are a medium length with a flat rectangular shape. They are traditionally made from brass or silver and are used simultaneously with a spoon.
Chinese chopsticks are longer and thicker than both Japanese and Korean chopsticks. They have squared or rounded sides and end in blunt, flat tips. They can be made from many materials but are most commonly made from melamine plastic or lacquered bamboo.
Vietnamese chopsticks are usually longer than most. These chopsticks taper to a blunt point like Chinese ones and are traditionally made from lacquered wood or bamboo.
