Battle-axes
A battle axe (also battle-axe, battle ax, or battle-ax) is an axe specifically designed for combat. Battle axes were specialized versions of utility axes. Many were suitable for use in one hand, while others were larger and were deployed two-handed. Axes designed for warfare ranged in weight from just over , and in length from just over to upwards of , as in the case of the Danish axe or the sparth axe. Cleaving weapons longer than 150 cm would arguably fall into the category of polearms. Overview Through the course of human history, commonplace objects have been pressed into service as weapons. Axes, by virtue of their ubiquity, are no exception. Besides axes designed for combat, there were many battle axes that doubled as tools. Axes could be modified into deadly projectiles as well (see the francisca for an example). Axes were often cheaper than swords and considerably more available. Battle axes generally weigh far less than modern splitting axes, especially ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Axe (tool)
An axe ( sometimes ax in American English; American and British English spelling differences#Miscellaneous spelling differences, see spelling differences) is an implement that has been used for Millennium, millennia to Wood carving, shape, Wood splitting, split and Woodchopping, cut wood, to harvest Lumber, timber, as a battle axe, weapon, and as a ceremony, ceremonial or Heraldry, heraldic symbol. The axe has many forms and specialised uses but generally consists of an axe head with a Handle (grip), handle, or ''helve''. Before the modern axe, the Stone Age, stone-age hand axe without a handle was used from 1.5 million years Before Present, BP. Hafted axes (those with a handle) date only from 6000 BC. The earliest examples of handled axes have heads of rock (geology), stone with some form of wooden handle attached (hafting, hafted) in a method to suit the available materials and use. Axes made of copper, bronze, iron and steel appeared as these technologies developed. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viking Age Arms And Armor
Knowledge about military technology of the Viking Age (late 8th to mid-11th century Europe) is based on relatively sparse archaeological finds, pictorial representation, and to some extent on the accounts in the Norse sagas and laws recorded in the 14th century. According to custom, all free Norse men were required to own weapons, and permitted to carry them at all times. Indeed, the ''Hávamál'', purported to be sage advice given by Odin, states "Don't leave your weapons lying about behind your back in a field; you never know when you may need all of sudden your spear." As war was the most prestigious activity in Viking Age Scandinavia, beautifully finished weapons were an important way for a warrior to display his wealth and status. A wealthy Viking would likely have a complete ensemble of a spear, a wooden shield, and either a battle axe or a sword. Battle axes were considered the "normal weapon" for middle class Vikings. Swords were normally reserved for upper class and n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bronze Age
The Bronze Age is a historic period, lasting approximately from 3300 BC to 1200 BC, characterized by the use of bronze, the presence of writing in some areas, and other early features of urban civilization. The Bronze Age is the second principal period of the three-age system proposed in 1836 by Christian Jürgensen Thomsen for classifying and studying ancient societies and history. An ancient civilization is deemed to be part of the Bronze Age because it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from production areas elsewhere. Bronze is harder and more durable than the other metals available at the time, allowing Bronze Age civilizations to gain a technological advantage. While terrestrial iron is naturally abundant, the higher temperature required for smelting, , in addition to the greater difficulty of working with the metal, placed it out of reach of common use until the end o ...

Copper Age
The Copper Age, also called the Chalcolithic (; from grc-gre, χαλκός ''khalkós'', "copper" and ''líthos'', "stone") or (A)eneolithic (from Latin '' aeneus'' "of copper"), is an archaeological period characterized by regular human manipulation of copper, but prior to the discovery of bronze alloys. Modern researchers consider the period as a subset of the broader Neolithic, but earlier scholars defined it as a transitional period between the Neolithic and the Bronze Age. The archaeological site of Belovode, on Rudnik mountain in Serbia, has the world's oldest securely dated evidence of copper smelting at high temperature, from (7000 BP). The transition from Copper Age to Bronze Age in Europe occurred between the late 5th and the late In the Ancient Near East the Copper Age covered about the same period, beginning in the late and lasting for about a millennium before it gave rise to the Early Bronze Age.

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Middle East
The Middle East ( ar, الشرق الأوسط, ISO 233: ) is a geopolitical region commonly encompassing Arabian Peninsula, Arabia (including the Arabian Peninsula and Bahrain), Anatolia, Asia Minor (Asian part of Turkey except Hatay Province), East Thrace (European part of Turkey), Egypt, Iran, the Levant (including Syria (region), Ash-Shām and Cyprus), Mesopotamia (modern-day Iraq), and the Socotra Governorate, Socotra Archipelago (a part of Yemen). The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term "Middle East" has led to some confusion over its changing definitions, and has been viewed by some to be discriminatory or too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of Western Asia (including Iran), but without the South Caucasus, and additionally includes all of Egypt (not just the Sina ...

Sledgehammer
A sledgehammer is a tool with a large, flat, often metal head, attached to a long handle. The long handle combined with a heavy head allows the sledgehammer to gather momentum during a swing and apply a large force compared to hammers designed to drive nails. Along with the mallet, it shares the ability to distribute force over a wide area. This is in contrast to other types of hammers, which concentrate force in a relatively small area. Etymology The word sledgehammer is derived from the Anglo Saxon "''slægan''", which, in its first sense, means "to strike violently". The English words "slag", "slay", and "slog" are cognates. Uses The handle can range from to a full long, depending on the mass of the head. The head mass is usually . Modern heavy duty sledgehammers come with heads. Sledgehammers usually require two hands and a swinging motion involving the entire torso, in contrast to smaller hammers used for driving in nails. The combination of a long swinging range ...

Splitting Maul
A splitting maul also known as a ''block buster'', ''block splitter'', ''chop and maul'', ''sledge axe'', ''go-devil'' or ''hamaxe'' is a heavy, long-handled axe used for splitting a piece of wood along its grain. One side of its head is like a sledgehammer, and the other side is like an axe. Tools ; Wedged mauls: A typical wood splitting maul has a head weight of 6 to 8 lb or approximately 2.7 to 3.6 kg, respectively. Traditionally, mauls have a wedge-shaped head, but some modern versions have conical heads or swiveling sub-wedges. The original maul resembles an axe but with a broader head. For splitting wood, this tool is much better than a typical axe. The weight of it is more advantageous, and it is less likely to become stuck in the wood thanks to its width. The wedge section of a maul head must be slightly convex to avoid jamming and it cannot have the elongated "hollow ground" concave-section that a cutting axe may use. Unlike an axe, maul handles are normall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metamorphic
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock (protolith) is subjected to temperatures greater than and, often, elevated pressure of or more, causing profound physical or chemical changes. During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition. The protolith may be an igneous, sedimentary, or existing metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface. They are classified by their protolith, their chemical and mineral makeup, and their texture. They may be formed simply by being deeply buried beneath the Earth's surface, where they are subject to high temperatures and the great pressure of the rock layers above. They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction, and distorti ...

Igneous
Igneous rock (derived from the Latin word ''ignis'' meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms, orogens, basins, large igneous provinces, extended crust and oceanic crust. Geological significance Igneous and metamorphic rocks make up 90–95% of the top ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Picrite
Picrite basalt or picrobasalt is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine. It is dark with yellow-green olivine phenocrysts (20-50%) and black to dark brown pyroxene, mostly augite. The olivine-rich picrite basalts that occur with the more common tholeiitic basalts of Kīlauea and other volcanoes of the Hawaiian Islands are the result of accumulation of olivine crystals either in a portion of the magma chamber or in a caldera lava lake. The compositions of these rocks are well represented by mixes of olivine and more typical tholeiitic basalt. The name "picrite" can also be applied to an olivine-rich alkali basalt: such picrite consists largely of phenocrysts of olivine and titanium-rich augite pyroxene with minor plagioclase set in a groundmass of augite and more sodic plagioclase and perhaps analcite and biotite. Picrites and komatiites are somewhat similar chemically (defined as >18% MgO), but differ in having 1 to 2% total alkalis ...
