"If you have been to Korean, Chinese and Japanese restaurants, you may have noticed that the chopstick sizes are different and from the three countries only Koreans traditionally use a spoon to eat rice. And among the three countries Korean utensils are metal. Because silver changes color when exposed to toxins, Korean royals used silver spoons and chopsticks to detect poison in their food. This practice became a trend for commoners and using metal utensils became a thing. When eating rice, unlike Japanese, Koreans do not pick up the bowl so the long length helps with movement."
