Chopsticks become an extension of your hand after you use them for a while. Its amazing. After using them for a month straight, I came back to the states finding a fork and knife awkward to use. Something to keep in mind when using chopsticks is that whatever is most comfortable for your hands is best. There is no one way to use chopsticks!(my roommate from Japan looked surprised when i asked her the best way and told me this.)
There is a difference between chopsticks in Japan and chopsticks in China. Chinese chopsticks are longer and rounded at the tip while Japanese chopsticks are shorter and pointed at the tip. In Chinese tradition, placing your hand as far back from the tip of the chopstick is considered most elegant.
