Chopsticks (Chinese: 筷子 or 箸; Pinyin: kuàizi or zhù) are shaped pairs of equal-length sticks of Chinese origin that have been used as kitchen and eating utensils in most of East and Southeast Asia for over three millennia. They are held in the dominant hand, secured by fingers, and wielded as extensions of the hand, to pick up food.
First used by the Chinese, chopsticks later spread throughout China and parts of Asia. Chopsticks have become more accepted in connection with Asian food in the West, especially in cities with significant Asian diaspora communities.
Chopsticks are smoothed, and frequently tapered. They are traditionally made of wood, bamboo, metal, ivory, and ceramics, and in modern days, increasingly available in non-traditional materials such as plastic, stainless steel, and even titanium. Chopsticks are often seen as requiring practice and skill to master to be used as an eating utensil. Although not as serious as before, in some countries it is often frowned upon if used incorrectly.

Chopsticks have been around and used since at least the Shang dynasty (1766–1122 BCE). However, the Han dynasty historian Sima Qian wrote that it is likely that chopsticks were also used in the preceding Xia dynasty and even the earlier Erlitou culture, although finding archeological evidence from this era is incredibly difficult.
The earliest evidence of chopsticks uncovered so far consists of six chopsticks, made of bronze, 26 centimeters (10 in) long, and 1.1 to 1.3 centimeters (0.43 to 0.51 in) wide, excavated from the Ruins of Yin near Anyang (Henan). These are dated roughly to 1200 BCE, during the Shang dynasty. They were supposed to have been used for cooking. The earliest known textual reference to the use of chopsticks comes from the Han Feizi, a philosophical text written by Han Fei (c. 280–233 BCE) in the 3rd century BCE.
The wide diffusion of chopsticks in the Chinese culture is sometimes attributed to the Confucian philosophy that emphasizes family harmony as the basis for civil order. Confucius himself have allegedly said that knives are for warriors, but chopsticks are for scholars, and his sucessor Mencius is linked to the aphorism "the honorable and upright man keeps well away from both the slaughterhouse and the kitchen… And he allows no knives on his table". Confucius references to chopsticks in his Book of Rites suggests these items were widely known in the Warring States period (c. 475–221 BC).
The first chopsticks were used for cooking, stirring the fire, serving or seizing bits of food, and not as eating utensils. One reason was that before the Han dynasty, millet was predominant in North China, Korea and parts of Japan. While chopsticks were used for cooking, millet porridge was eaten with spoons at that time.: 29-35 The use of chopsticks in the kitchen continues to this day.
Ryōribashi (料理箸) are Japanese kitchen chopsticks used in Japanese cuisine. They are used in the preparation of Japanese food, and are not designed for eating. These chopsticks allow handling of hot food with one hand, and are used like regular chopsticks. These chopsticks have a length of 30 centimeters (12 in) or more, and may be looped together with a string at the top. They are usually made from bamboo. For deep frying, however, metal chopsticks with bamboo handles are preferred, as tips of regular bamboo chopsticks become discolored and greasy after repeated use in hot oil. The bamboo handles protect against heat.
Similarly, Vietnamese cooks use đũa cả (𥮊奇) or "grand chopsticks" in cooking, and for serving rice from the pot.
Chopsticks began to be used as eating utensils during the Han dynasty, as rice consumption increased. During this period, spoons continued to be used alongside chopsticks as eating utensils at meals. It was not until the Ming dynasty that chopsticks came into exclusive use for both serving and eating. They then acquired the name kuaizi and the present shape.: 6-8
The use of chopsticks as both cooking and eating utensils spread throughout East and Southeast Asia over time. Scholars such as Isshiki Hachiro and Lynn White have noted how the world was split among three dining customs, or food cultural spheres. There are those eating with fingers, and those with forks and knives. Then there is the "chopsticks cultural sphere", consisting of China, Japan, Korea, Taiwan, and Vietnam.: 1-3, 67-92
As ethnic Chinese emigrated, they also spread the customs of the usage of chopsticks as eating utensils, and has now also been used in certain ethnic foods in South and Southeast Asian countries such as Cambodia, Laos, Nepal, Malaysia, Myanmar, Singapore and Thailand. In Singapore and Malaysia, the ethnic Chinese traditionally consume all food with chopsticks, while ethnic Indians and Malays (especially in Singapore) use chopsticks to consume noodle dishes. Overall, the use of a spoon or fork or chopsticks are interchangeable in these regions. In Laos, Myanmar, Thailand and Nepal chopsticks are generally used only to consume noodles.: 1–8
Similarly, chopsticks have become more accepted in connection with Asian food around the world, in Hawaii, the West Coast of North America, and cities with Overseas Asian communities all around the globe.
The earliest European reference to chopsticks comes in the Portuguese Suma Oriental by Tomé Pires, who wrote in 1515 in Malacca: "They [the Chinese] eat with two sticks and the earthenware or china bowl in their left hand close to the mouth, with the two sticks to suck in. This is the Chinese way."
In ancient written Chinese, the character for chopsticks was zhu (箸; Middle Chinese reconstruction: d̪jwo-). Although it may have been widely used in ancient spoken Chinese, its use was eventually replaced by the pronunciation for the character kuài (快), meaning "quick". The original character, though still used in writing, is rarely used in modern spoken Chinese. It, however, is preserved in Chinese dialects such as Hokkien and Teochew, as the Min Chinese languages are directly descended from Old Chinese rather than Middle Chinese.
The Standard Chinese term for chopsticks is kuàizi (筷子). The first character (筷) is a pictophonetic (semantic-phonetic) compound created with a phonetic part meaning "quick" (快), and a semantic part meaning "bamboo" (竹), using the radical (⺮).
The English word "chopstick" may have derived from Chinese Pidgin English, in which chop chop meant "quickly". According to the Oxford English Dictionary, the earliest published use of the word is in the 1699 book Voyages and Descriptions by William Dampier: "they are called by the English seamen Chopsticks". Another possibility, is that the term is derived from chow (or chow chow) which is also a pidgin word stemming from Southeast Asia meaning "food". Thus chopsticks would simply mean "food sticks".
In Japanese, chopsticks are called hashi (箸). They are also known as otemoto (おてもと), a phrase commonly printed on the wrappers of disposable chopsticks. Te means hand and moto means the area under or around something. The preceding o is used for politeness.
In Okinawan, chopsticks are called mēshi (めーし) as a vulgar word, umēshi (うめーし) as a polite word, or 'nmēshi ぅんめーし(citation needed], ʔNmeesi). A special type of chopsticks made from the himehagi (Polygala japonica) stem is called sōrō 'nmēshi (そーろーぅんめーし, sooroo ʔNmeesi ). These are used at altars of offerings in Kyū Bon (old Bon Festival).[
In Korean, 저 (箸, jeo) is used in the compound jeotgarak (젓가락), which is composed of jeo ("chopsticks") and garak ("stick"). Jeo cannot be used alone, but can be found in other compounds such as sujeo (수저) ("spoon and chopsticks").
In Indonesian, chopsticks are called sumpit.
In Taiwanese Hokkien, which is derived from Hokkien, chopsticks are called tī, written as 箸.
In Vietnamese, chopsticks are called đũa, which is written as 箸 in Chữ Nôm. Đũa is the non-Sino-Vietnamese reading of 箸. An alternative character is 𥮊.
In Cambodian (Khmer), chopsticks are called chang keuh (ចង្កឹះ).
Chopsticks come in a wide variety of styles, with differences in geometry and material. Depending on the country and the region some chopstick styles are more common than others.
Chinese chopsticks tend to be longer than other styles, at about 27 centimeters (11 in). They are thicker, with squared or rounded cross-sections. They end in either wide, blunt, flat tips or tapered pointed tips. Blunt tips are more common with plastic or melamine varieties, whereas pointed tips are more common in wood and bamboo varieties. Chinese restaurants more commonly offer melamine chopsticks for its durability and ease of sanitation. Within individual household, bamboo chopsticks are more commonly found.
It is common for Japanese sticks to be of shorter length for women, and children's chopsticks in smaller sizes are common. Many Japanese chopsticks have circumferential grooves at the eating end, which helps prevent food from slipping. Japanese chopsticks are typically sharp and pointed, in order to dissect fish and seafood. They are traditionally made of wood or bamboo, and are lacquered.
Lacquered chopsticks are known in Japanese as nuribashi, in several varieties, depending on where they are made and what types of lacquers are used in glossing them.: 80–87 Japan is the only place where they are decorated with natural lacquer, making them not just functional but highly attractive. Japanese traditional lacquered chopsticks are produced in the city of Obama in Fukui Prefecture, and come in many colors coated in natural lacquer. They are decorated with mother-of-pearl from abalone, and with eggshell to impart a waterproof coating to the chopsticks, extending their life.
Edo Kibashi chopsticks have been made by Tokyo craftspeople since the beginning of the Taishō Period (1912-1926) roughly 100 years ago. These chopsticks use high-grade wood (ebony, red sandalwood, ironwood, Japanese box-trees, or maple), which craftspeople plane by hand. Edo Kibashi chopsticks may be pentagonal, hexagonal or octagonal in cross-section. The tips of these chopsticks are rounded to prevent to damage the dish or the bowl.
In Japan, chopsticks for cooking are known as ryoribashi (料理箸 りょうりばし), and as saibashi (菜箸 さいばし) when used to transfer cooked food to the dishes it will be served in.
The earliest uses of chopsticks in Korea seem to date back to the Three Kingdoms of Korea with the oldest chopsticks excavated from the royal tomb of Baekje. Chopsticks used by Koreans are often made of metal. It is believed that the uses of metallic chopsticks evolved from the royal practice of using silver chopsticks to detect poison in food, but the exact reason is debated. Depending on the historical era, the metallic composition of Korean chopsticks varied. In the past, such as during the Goryeo era, chopsticks were made of bronze. During the Joseon era, chopsticks used by royalty were made of silver, as its oxidizing properties could often be used to detect whether or not food intended for royals had been tampered with. In the present day, the majority of Korean metal chopsticks are made of stainless steel. Due to metal's slippery nature, the chopsticks are stamped flat for better gripping. High-end sets, such as those intended as gifts, are often made of sterling silver. Chopsticks made of varying woods (typically bamboo) are also common in Korea. Many Korean chopsticks are ornately decorated at the grip.
In North and South Korea, chopsticks of medium-length with a small, flat rectangular shape are paired with a spoon, made of the same material. The set is called sujeo, a portmanteau of the Korean words for spoon and chopsticks. This (the historical extensive use of a spoon in addition to chopsticks) is also a feature unique to Korea; most chopstick-using countries have either eliminated the use of spoons, or have limited their use as eating utensils. It is traditional to rest sujeo on spoon and chopstick rest, so chopsticks and the spoon do not touch the table surface.
In the past, materials for sujeo varied with social class: Sujeo used in the court were made with gold, silver, or cloisonné, while commoners used brass or wooden sujeo. Today, sujeo is usually made with stainless steel, although bangjja is also popular in more traditional settings.
Vietnamese chopsticks are long sticks that taper to a blunt point. They are usually big and thick at one end and thinner at the other, thin ends are often used to pick up food. They are traditionally made of bamboo or lacquered wood. Đũa cả (Chữ Nôm: 𥮊奇) are large, flat chopsticks used to serve rice from a pot. Plastic chopsticks are also used due to their durability. However, bamboo or wooden chopsticks are often more popular, especially in the village countryside (quê).
The Thais tend to use their hands when eating their native cuisine. Ethnic Chinese immigrants introduced the use of chopsticks for foods that require them. Restaurants serving other Asian cuisines that utilize chopsticks use the style of chopstick, if any, appropriate for that cuisine. Fork and spoon, adopted from the West, are also used.
Bamboo chopsticks called candas are used to eat ambuyat or linut in Borneo, a native staple food of glutinous porridge made from sago. A pair of candas is typically adjoined at the back.
Lifelong users and adult learners alike, around the world, hold chopsticks in more than one way. But there is a general consensus on a standard grip being the most efficient way to grip and wield chopsticks.
Regardless of whether users wield the standard grip, or one of many alternative grips, their goals are the same. They hold the two sticks in the dominant hand, secured by various fingers and parts of the hand, such that the sticks become an extension of the hand. Tsung-Dao Lee, a Nobel Prize Laureate in Physics, summarized it thus: "Although simple, the two sticks perfectly use the physics of leverage. Chopsticks are an extension of human fingers. Whatever fingers can do, chopsticks can do, too.": 14
Alternative grips differ in their effectiveness in picking up food. They differ in the amount of pinching (compression) power they can generate. Some grips can generate substantial, outward extension force, while others are unable to do so.
The standard grip calls for the top chopstick to be held by the tip of the thumb, the tip of the index finger, and the middle finger knuckle. These three fingers surround the top stick from three sides, and firmly secure the stick as if they were holding a pen. The three fingers, using this tripod-like hold, can wiggle and twirl the top stick, as if it were an extension of them. The rear end of the top stick rests on the base of the index finger.
The bottom chopstick, on the other hand, generally remains immobile. It is secured by the base of the thumb, which presses the stick against the knuckle of the ring finger, and against the purlicue. The thumb therefore does double duty. It holds the bottom stick immobile, and at the same time, it also moves the top stick. The thumb must be flattened, in order to perform this double duty.
In chopstick-using cultures, learning to use chopsticks is part of a child's development process. The right way to use chopsticks is usually taught within the family.[B] But many young children find their own ways of wielding chopsticks in the process. There exists a variety of learning aids that parents purchase to help their children learn to use chopsticks properly.
Adult learners, on the other hand, may acquire the skill through personal help from friends, or from instructions printed on wrapper sleeves of some disposable chopsticks. Various video hosting platforms also provide a plethora of how-to videos on learning to use chopsticks. All the same, adult learners too, often find their own alternative grips to using chopsticks.
In general, learning aids attempt to steer learners towards the established standard grip. These aids attempt to illustrate or enforce the right standard grip mechanical leverage.
The learning process usually starts with a proper initial placement of fingers, per standard grip. It is crucial for learners to understand how to hold both sticks firmly in the hand, as extensions of fingers.
The next step involves learning the right motion of fingers, in order to move the top stick from the closed posture where tips of chopsticks touch, to the open posture where tips are extended wide apart for embracing food items. The open posture and the closed posture define the two ends of maximum standard grip motion. In most eating situations, tips of chopsticks need not be extended this wide apart.
Both finger placement and standard grip motion rely on the thumb being flattened. With this flat thumb pose, the base of the thumb can exert enough force to pin the bottom stick against the knuckle of the ring finger, and against the purlicue. At the same time, the tip of the thumb pushes back against the index finger and the knuckle of the middle finger, as all three wield the top stick in concert.
The shape of the flat thumb is such that the bottom stick is prevented from shaking loose, and from inching closer to the top stick, during repeated standard grip motion. Keeping the two chopsticks separated far enough, at the place they intersect with the thumb, is important for the standard grip. At the open posture, it allows tips to extend wide apart, without rear ends of chopsticks colliding. At the closed posture, it enables better control over tips of chopsticks.[B]
The most popular chopstick learning aid is arguably the wrapper-sleeve-and-rubber-band model, which is used in ethnic restaurants around the world. These are mostly operated like tweezers, or tongs. While they are useful for picking up food, they do not help learners acquire the standard grip. Many similar chopstick inventions can be found on the market, such as Kwik Stix. Some inventions combine other utensils with chopsticks. These include The Chork, the Fork and Knife Chopsticks, etc.
Some learning aids help learners with the initial placement of fingers, per standard grip. This can be done by making "index finger", "thumb tip", or equivalent labels at the right places on chopsticks. Often these chopsticks will have finger-shaped grooves carved out of sticks, to further help learners find the right placement. Other finger placement chopsticks instead carve circumferential grooves into sticks, in place of finger-shaped ones.
Some learning aids allow users to wield two sticks as extensions of their fingers, without the exact finger dynamics required by the standard grip. Some models provide hoops through which fingers can move the top chopstick as an exoskeleton of these fingers. Other models use finger-shaped tabs instead to achieve the same, for both top and bottom sticks. Yet other models combine finger placement features with the above. Usually these models connect the two chopsticks with a bridge and a hinge, holding the two sticks in the right configuration on behalf of users.
Chopsticks are used in many parts of the world and principles of etiquette are similar, but finer points can differ from region to region. Chopstick manners were gradually shaped to work with a culture's particular dietary varieties and habit. Etiquette developed for primarily individual servings eaten on the floor (or tatami in the case of Japan) could be different from communal meals eaten around a table while seated on chairs. The need for serving or communal chopsticks similarly differ. In some cultures it is customary to lift a bowl to the mouth, when the only eating utensil used is chopsticks. In other cultures, lifting a bowl closer to the mouth is frowned upon as equivalent to begging, as the local custom is to use chopsticks for chunky food, and a spoon for liquid food.: 102-119
In chopstick-using countries, holding chopsticks incorrectly reflects negatively on a child's parents and home environment. There are frequent news articles on the alarming decline of children's abilities to use chopsticks correctly. Similarly, stabbing food due to one's inability to wield chopsticks with dexterity is also frowned upon. : 73-75 
In general, chopsticks should not be left vertically stuck into a bowl of rice because it resembles the ritual of incense-burning that symbolizes "feeding" the dead.

Vietnam is one of the countries in the original "chopsticks cultural sphere". Its customs are heavily influenced by its Chinese counterparts, including using chopsticks exclusively as eating utensils. Consequently Vietnamese chopstick etiquette is very similar to the Chinese version.: 69, 73 For instance, it is deemed proper to hold the bowl close to the mouth, just like is the case in China. Holding chopsticks vertically up like incense sticks is taboo. Tapping bowls with chopsticks is frowned upon.
Although there are some similarities with China, they still have some differences, some other common Vietnamese taboos are:
In Cambodia, chopsticks, spoon and fork, and hands are the primary eating utensils. Although chopsticks are commonly used for noodle dishes, most Cambodians use chopsticks for any meal. And because Cambodia adopted the spoon and fork later than their neighboring countries such as Thailand, it is common to see Cambodians use chopsticks for any meals. Forks are only used to help guide food onto the spoon. Forks are not used to shovel food into the mouth. For noodle dishes such as kuyteav and num banhchok, chopsticks are used. Cambodians do not use forks at all to put food in their mouth because they are seen as dangerous near the mouth area. And the soup spoon is used for the broth.
The most widespread use of disposable chopsticks is in Japan, where around a total of 24 billion pairs are used each year, which is equivalent to almost 200 pairs per person yearly. In China, an estimated 45 billion pairs of disposable chopsticks are produced yearly. This adds up to 1.66 million cubic meters (59×106 cu ft) of timber or 25 million fully grown trees every year.
In April 2006, China imposed a 5% tax on disposable chopsticks to reduce waste of natural resources by overconsumption. This measure had the most effect in Japan as many of its disposable chopsticks are imported from China, which account for over 90% of the Japanese market.
American manufacturers have begun exporting American-made chopsticks to China, using sweet gum and poplar wood as these materials do not need to be artificially lightened with chemicals or bleach, and have been seen as appealing to Chinese and other East Asian consumers.
The American-born Taiwanese singer Wang Leehom has publicly advocated the use of reusable chopsticks made from sustainable materials. In Japan, reusable chopsticks are known as maihashi or maibashi (マイ箸, meaning "my chopsticks").
A 2006 Hong Kong Department of Health survey found that, since 2003, the proportion of people using distinctly separate serving chopsticks, spoons, or other utensils for serving food from a common dish has increased from 46% to 65%.

The proper way to use a pair is to place the first chopstick between the base of the thumb and the top of the ring finger (this chopstick remains stationary) and the second one between the top of the thumb and the middle and index fingers.
