As a piece of cutlery or kitchenware, a fork is a tool consisting of a handle with several narrow tines (usually two, three or four) on one end. The fork as an eating utensil was a feature primarily of the West, whereas in East Asia chopsticks were more prevalent. Today, however, forks are increasingly available throughout East Asia as well.
The utensil (usually metal) is used to lift food to the mouth or to hold food in place while cooking or cutting it. Food can be lifted either by spearing it on the tines, or by collecting it on top of the tines, and holding it atop the tines horizontally. To allow for this spoon-like use, the tines are often curved slightly upward.
The word fork is derived from the Latin furca, meaning "pitchfork". Although the Greeks used  the fork as an apparent serving utensil, it is also mentioned in the Hebrew Bible, in the Book of I Samuel 2:13 ("The custom of the priests with the people was that when any man offered sacrifice, the priest’s servant came, while the flesh was boiling, with a fork of three teeth in his hand..."), it wasnt commonly used in Western Europe until the 10th century.
Before the fork was introduced, Westerners were reliant on the spoon and knife as the only eating utensils. Thus, people would largely eat food with their hands, calling for a common spoon when required. Members of the aristocracy would sometimes be accustomed to manners considered more proper and hold two knives at meals and use them both to cut and transfer food to the mouth, using the spoon for soups and broth.
The earliest forks usually had only two tines, but those with numerous tines caught on quickly. The tines on these implements were straight, meaning the fork could only be used for spearing food and not for scooping it. The fork allowed meat to be easily held in place while being cut. The fork also allowed one to spike a piece of meat and shake off any undesired excess of sauce or liquid before consuming it. First introduced to Western Europe in the 10th century byTheophanu, Byzantine wife of Emperor Otto II, the table fork had, by the 11th century, made its way to Italy. In Italy, it became quite popular by the 14th century, being commonly used for eating by merchant and upper classes by 1600. It was proper for a guest to arrive with his own fork and spoon enclosed in a box called a cadena; this usage was introduced to the French court with Catherine de' Medici's entourage. Long after the personal table fork had become commonplace in France, at the supper celebrating the marriage of the duc de Chartres to Louis XIV's natural daughter in 1692, the seating was described in the court memoirs ofSaint-Simon:"King James having his Queen on his right hand and the King on his left, and each with their cadenas." In Perrault's contemporaneous fairy tale ofLa Belle au bois dormant (1697), each of the fairies invited for the christening is presented with a splendid "Fork Holder"
The fork's arrival in northern Europe was more difficult. Its use was first described in English by Thomas Coryat in a volume of writings on his Italian travels (1611), but for many years it was viewed as an unmanly Italian affectation. Some writers of the Roman Catholic Church expressly disapproved of its use, seeing it as "excessive delicacy": "God in his wisdom has provided man with natural forks — his fingers. Therefore it is an insult to Him to substitute artificial metallic forks for them when eating." It was not until the 18th century that the fork became commonly used in Great Britain. It was around this time that the curved fork used today was developed in Germany. The standard four-tine design became current in the early nineteenth century.
The 20th century also saw the emergence of the "spork", a utensil that is half fork and half spoon. With this new "fork-spoon", only one piece of cutlery is needed when eating (so long as no knife is required). The back of the spork is shaped like a spoon and can scoop food while the front has shortened tines like a fork, allowing spearing of food, making it convenient and easy to use. It has found popularity in fast food and military settings.
