A dagger is a knife with a sharp point and two sharp edges designed or capable of being used as a thrusting or stabbing weapon. Daggers have been used throughout human history for close combat confrontations, many cultures have used adorned daggers in ritual and ceremonial contexts; the distinctive shape and historic usage of the dagger have made it symbolic. A dagger in the modern sense is a weapon designed for close-proximity self-defense. Double-edged knives, play different sorts of roles in different social contexts. In some cultures, they are neither a potent symbol of manhood. A wide variety of thrusting knives have been described as daggers, including knives that feature only a single cutting edge, such as the European rondel dagger or the Persian pesh-kabz, or, in some instances, no cutting edge at all, such as the stiletto of the Renaissance. However, in the last hundred years or so, in most contexts, a dagger has certain definable characteristics, including a short blade with a tapered point, a central spine or fuller, two cutting edges sharpened the full length of the blade, or nearly so.

Most daggers feature a full crossguard to keep the hand from riding forwards onto the sharpened blade edges. Daggers are weapons, so knife legislation in many places restricts their manufacture, possession, transport, or use; the earliest daggers were made of materials such as ivory or bone in Neolithic times. Copper daggers appeared first in the early Bronze Age, in the 3rd millennium BC, copper daggers of Early Minoan III were recovered at Knossos. In ancient Egypt, daggers were made of copper or bronze, while royalty had gold weapons. At least since pre-dynastic Egypt, daggers were adorned as ceremonial objects with golden hilts and even more ornate and varied construction. One early silver dagger was recovered with midrib design; the 1924 opening of the tomb of Tutankhamun revealed two daggers, one with a gold blade, one of smelted iron. It is held. Circa B. C. 1600. As late as Mene-ptah II. of the Nineteenth Dynasty, we read it in the list of his loot, after the Prosopis battle, of bronze armour and daggers.

Iron production did not begin until 1200 BC, iron ore was not found in Egypt, making the iron dagger rare, the context suggests that the iron dagger was valued on a level equal to that of its ceremonial gold counterpart. These facts, the composition of the dagger had long suggested a meteoritic origin, evidence for its meteoritic origin was not conclusive until June 2016 when researchers using x-ray fluorescence spectrometry confirmed similar proportions of metals in a meteorite discovered in the area, deposited by an ancient meteor shower. One of the earliest objects made of smelted iron is a dagger dating to before 2000 BC, found in a context that suggests it was treated as an ornamental object of great value. Found in a Hattic royal tomb dated about 2500 BC, at Alaca Höyük in northern Anatolia, the dagger has a smelted iron blade and a gold handle; the artisans and blacksmiths of Iberia in what is now southern Spain and southwestern France produced various iron daggers and swords of high quality from the 5th to the 3rd century BC, in ornamentation and patterns influenced by Greek and Phoenician culture.

The exceptional purity of Iberian iron and the sophisticated method of forging, which included cold hammering, produced double-edged weapons of excellent quality. One can find technologically advanced designs such as folding knives rusted among the artifacts of many Second Iberian Iron Age cremation burials or in Roman Empire excavations all around Spain and the Mediterranean. Iberian infantrymen carried several types of iron daggers, most of them based on shortened versions of double-edged swords, but the true Iberian dagger had a triangular-shaped blade. Iberian daggers and swords were adopted by Hannibal and his Carthaginian armies; the Lusitanii, a pre-Celtic people dominating the lands west of Iberia held off the Roman Empire for many years with a variety of innovative tactics and light weapons, including iron-bladed short spears and daggers modeled after Iberian patterns. During the Roman Empire, legionaries were issued a pugio, a double-edged iron thrusting dagger with a blade of 7–12 inches.

The design and fabrication of the pugio was taken directly from short swords. Like the gladius, the pugio was most used as a thrusting; as an extreme close-quarter combat weapon, the pugio was the Roman soldier's last line of defense. When not in battle, the pugio served as a convenient utility knife; the term dagger appears only in the Late Middle Ages, reflecting the fact that while the dagger had been known in antiquity, it had disappeared during the Early Middle Ages, replaced by the hewing knife or seax. The dagger reappeared in the 12th century as the "knightly dagger", or more properly cross-hilt or quillon dagger, was developed into a common arm and tool for civilian use by the late medieval period; the earliest known depiction of a cross-hilt dagger is the so-called "Guido relief" inside the Grossmünster of Zürich.

White British

White British is an ethnicity classification used in the 2011 United Kingdom Census. In the 2011 census, the White British population was 81.9 % of the UK total population.

The following numbers were based on the 2011 census conducted in each country. In England and Wales, about 64 per cent of the White British classification are between the ages of 16 and 64 while about 18 per cent are under 16 and 19 per cent are over 64. All other census classifications have a higher percentage of their population under 16 and a lower percentage over 64. Of those aged 65 or over, White British are 8 per cent male and 10 per cent female, making them have the lowest per cent male population among all census classifications defined as "ethnic" in the census. In Scotland, about 65 per cent of the White British classification are between the ages of 16 and 24 while about 17 per cent are under 16 and 18 per cent are over 64. Of those aged 65 or over, White British are 8 per cent male and 10 per cent female, the same percentages as in England and Wales.

Of those aged 25 or over, white people are 34 per cent female. According to the 2011 UK Census results, White British people make up the largest percentage of the population in rural areas, such as Allerdale and Copeland in Cumbria, Ryedale in North Yorkshire, North Norfolk and North Devon. Cities across the UK regions with high White British populations include Swansea, Plymouth, England, Norwich, Chelmsford and Lichfield, England. Within London, Havering has the highest White British percentage with 83.3%, followed by Bromley with 77.4%, Bexley with 77.3% and Richmond upon Thames with 71.4%. Since the 2011 UK Census was returned, London contains by far the lowest percentage of English and other White British people of all the UK regions, where they make up less than half of the population in 24 of the 32 boroughs, including: Newham, Ealing, Tower Hamlets and Hackney; the city with the lowest White British population as a percentage is Leicester. The unitary authority with the lowest White British percentage is Slough, followed by Luton..

According to official UK Government figures from 2016, the employment rate for White British people stood at 75%, with the overall employment rate in the UK standing at 74%.

Whitty Street

Whitty Street is a street in Shek Tong Tsui, Hong Kong Island, Hong Kong. Named after R. C. Whitty, the first manager of Hong Kong and China Gas Company, the street is well known as one of seven terminals of the Hong Kong Tramway; the road starts from Queen's Road West, crossing Des Voeux Road West and ends in Connaught Road West. In the 1970s, there was a plan for an MTR station to be built beneath the street for the residents of Shek Tong Tsui. Space is reserved for the exit of the future station. Nonetheless, the plan has never come to fruition. A new plan suggests that a station would be built near the private housing estate The Belcher's instead of on Whitty Street.
