Chopsticks appeared about 3 thousand years ago in China. Kuayzi - square at the base, so as not to roll on the table, about 25 cm long - they are made of wood, metal, plastic, bone.
In the 6th-7th centuries, silver sticks were sometimes used to check food for the presence of poison; in those days one of the common poisons was arsenic, upon contact with which the silver sticks darkened.
Interestingly, 30% of people use chopsticks - the same number as fork users. Others eat with their hands.
The tradition of eating with chopsticks from the Chinese was adopted by the Japanese, Koreans, Vietnamese and other peoples of the East, but this happened only in the 12th century. In each of these countries, the sticks look different.
Japanese hasi are also made of wood, but they are shorter than Chinese kuaizu and have sharper ends. For the Japanese, sticks are not only an everyday personal item. They are presented to newlyweds, implying the desire to be as inseparable as a pair of sticks. They are presented to the baby on the 100th day from the moment of his birth, when during the ceremony "First sticks" adults for the first time give him rice to taste with the help of sticks. For hasi, a special stand is used - hasioki, on which it is customary to put sticks with thin ends so that they look to the left.
The Japanese claim that according to their research, children who start eating with hashi right after they turn one year outpace their spoon-eating peers.
In Korea, they eat with thin metal sticks. This is a unique custom of its kind - in no other country in the Far East where chopsticks are used, they are not made of metals. Earlier, Korean chopsticks were made of brass, now they are mainly made of stainless steel. In Korea, it is customary to eat rice with a spoon, especially in the presence of elders.
Nowadays, most restaurants serve disposable sticks (varibashi) made of plastic or wood. Usually they are produced connected (the upper ends of the sticks are not sawn, as evidence that they were not used).
In China alone, about 45 billion pairs of disposable wooden sticks are used and discarded annually, which is approximately 1.7 million cubic meters of wood or 25 million destroyed trees per year. In order to protect the environment, since April 2006, China has introduced a 5% sales tax on disposable sticks, and in Beijing, China, many hotels have abandoned them.
Many Asian manufacturers of microcircuits and LCD monitors, when hiring personnel at the factory, conduct a coordination test: you need to quickly collect small beads with chopsticks.
