Blade
A blade is the Sharpness (cutting), sharp, cutting portion of a tool, weapon, or machine, specifically designed to puncture, chop, slice, or scrape surfaces or materials. Blades are typically made from materials that are harder than those they are intended to cut. This includes early examples made from flaked stones like flint or obsidian, evolving through the ages into metal forms like copper, bronze, and iron, and culminating in modern versions made from steel or ceramics. Serving as one of humanity's oldest tools, blades continue to have wide-ranging applications, including in combat, cooking, and various other everyday and specialized tasks. Blades function by concentrating force at the cutting edge. Design variations, such as serrated edges found on bread knives and saws, serve to enhance this force concentration, adapting blades for specific functions and materials. Blades thus hold a significant place both historically and in contemporary society, reflecting an evolution i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kukri
The kukri () or khukuri (, ) is a type of knife or short sword with a distinct recurve in its blade that originated in the Indian subcontinent. It serves multiple purposes as a melee weapon and also as a regular cutting/chopping tool throughout most of South Asia. The ''kukri'', ''khukri'', and ''kukkri'' spellings are of Indian English origin. The kukri is the national weapon of Nepal, traditionally serving the role of a basic utility knife for the Nepali language, Nepali-speaking Gurkhas, and consequently is a characteristic weapon of the Nepali Army. There are many myths surrounding the kukri since its earliest recorded use in the 7th century—most notably a traditional custom that the blade must draw blood before being sheathed, when its sole purpose is considered as a fighting weapon. In addition to its use in combat, the kukri is also used for a variety of other purposes. It is used by farmers and laborers for cutting crops and clearing brush, and by hunters for skinnin ...

Kitchen Knife
A kitchen knife is any knife that is intended to be used in food preparation. While much of this work can be accomplished with a few general-purpose knives — notably a large chef's knife and a smaller serrated blade utility knife — there are also many specialized knives that are designed for specific tasks such as a tough cleaver, a small paring knife, and a bread knife. Kitchen knives can be made from several different materials, though the most common is a hardened steel blade with a wooden handle. Historically, knives were made in "knife cities" that are noted for being the best at their production in that country with the pre-emininent, in Europe, being: Sheffield in Yorkshire, North of England; Thiers, Puy-de-Dôme in the Auvergne of France; Solingen in the Northern Rhineland of Germany; and Eskilstuna of Södermanland County in Sweden. Each of these produced knives in a styles particular to the city, with Thiers especially being noted for the French point of ...

Rapier
A rapier () is a type of sword originally used in Spain (known as ' -) and Italy (known as '' spada da lato a striscia''). The name designates a sword with a straight, slender and sharply pointed two-edged long blade wielded in one hand. It was widely popular in Western Europe throughout the 16th and 17th centuries as a symbol of nobility or gentleman status. It is called because it was carried as an accessory to clothing, generally used for fashion and as a weapon for dueling, self-defense and as a military side arm. Its name is of Spanish origin and appears recorded for the first time in the '' Coplas de la panadera'', by Juan de Mena, written approximately between 1445 and 1450: As fencing spread throughout Western Europe, important sources for rapier fencing arose in Spain, known under the term ("dexterity"), in Italy and France. The French small sword or court sword of the 18th century was a direct continuation of this tradition of fencing. Rapier fencing form ...

Talwar
The talwar (), also spelled talwaar and tulwar, is a type of curved sword or sabre from the Indian subcontinent. Etymology and classification The word ''talwar'' originated from the Sanskrit Language, Sanskrit word ''taravāri'' () which means "one-edged sword". It is the word for ''sword'' in several related languages, such as Hindustani language, Hindustani (Hindi and Urdu), Nepali language, Nepali, Marathi language, Marathi, Gujarati language, Gujarati, Punjabi language, Punjabi, etc. and as () in Bengali language, Bengali. Like many swords from around the world with an etymology derived from a term meaning simply 'sword', the talwar has in scholarship, and in museum and collector usage, acquired a more specific meaning. However, South Asian swords, while showing a rich diversity of forms, suffer from relatively poor dating (so developmental history is obscure) and a lack of precise nomenclature and classification. The typical talwar is a type of sabre, characterised by a c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballistic Knife
A ballistic knife is a knife with a detachable blade that can be ejected to a distance of several meters/yards by pressing a trigger or operating a lever or switch on the handle.Crawford, Steve, ''Deadly fighting skills of the world'', New York: Thomas Dunne Books, St. Martin's Press, (1999), pp. 45-46: The minimum standard demanded of ''Spetsnaz'' recruits when throwing a knife from six feet is three consecutive hits on target; five hits is considered excellent. Spring-powered ballistic knives first appeared in books and press reports on Soviet and Eastern Bloc armed forces in the late 1970s. Commercially-produced ballistic knives gained notoriety in the United States in the mid-1980s after being marketed and sold in the United States and other Western countries. Since then, the marketing and sale of ballistic knives to civilians has been restricted or prohibited by law in several nations. Usage In its spring-propelled form, the blade of a ballistic knife is theoretically capa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sharpness (cutting)
Sharpness refers to the ability of a blade, point, or cutting implement to cut through materials with minimal force, and can more specifically be defined as the capacity of a surface to initiate the cut.S. Schuldt, G. Arnold, J. Kowalewski, Y. Schneider, H. Rohm,Analysis of the sharpness of blades for food cutting, ''Journal of Food Engineering'', Volume 188 (2016), pp. 13–20, ISSN 0260-8774, DOI: https://doi.org/10.1016/j.jfoodeng.2016.04.022. Sharpness depends on factors such as the edge angle, edge width, and the fineness of the cutting edge, and is aided by material hardness. This quality is found in a variety of naturally occurring forms, including certain kinds of Rock (geology), rock, in plant thorns and spines, and in animal teeth, claws, horns, and other structures serving various purposes. Sharpness is also a critical attribute for man-made tools ranging from kitchen knives and scissors to industrial cutting equipment, as it allows the user of a sharp implement to eff ...

Saws
A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge used to cut through material. Various terms are used to describe toothed and abrasive saws. Saws began as serrated materials, and when mankind learned how to use iron, it became the preferred material for saw blades of all kinds. There are numerous types of hand saws and mechanical saws, and different types of blades and cuts. Description A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge. It is used to cut through material, very often wood, though sometimes metal or stone. Terminology A number of terms are used to describe saws. Kerf The narrow channel left behind by the saw and (relatedly) the measure of its width is known as the kerf. As such, it also refers to the wasted material that is turned into sawdust, and becomes a factor in measurements when making cuts. For example, cutting an 8-foot (2.4 meter) piece of wood into 1 foot (30 cm) sect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khopesh
The ''khopesh'' ('; also vocalized khepesh) is an Egyptian sickle-shaped sword that developed from battle axes. The sword style originated in Western Asia during the Bronze Age and was introduced in the Second Intermediate Period.Lloyd, Alan B. ''A Companion to Ancient Egypt''. Spalinger, Anothony J. Ch 23. "Military Institutions and Warfare: Pharaonic". Newark, United Kingdom: John Wiley & Sons, 2010.Van De Mieroop, Marc. ''A History of Ancient Egypt''. John Wiley & Sons, 2021. p. 126. The ''khopesh'' became more common in the New Kingdom, and is often depicted with kings in statues and murals. Etymology The word ''khopesh'' may have been derived from "leg", as in "leg of beef", because of their similarity in shape. The hieroglyph for ''ḫpš'' ('leg') is found as early as during the time of the Coffin Texts (the First Intermediate Period). Coffin Texts: However, on the 196 BC Rosetta Stone, it is referenced as the "sword" determinative in a hieroglyph block, with t ...

Bronze
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals (such as phosphorus) or metalloids (such as arsenic or silicon). These additions produce a range of alloys some of which are harder than copper alone or have other useful properties, such as strength, ductility, or machinability. The archaeological period during which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia is conventionally dated to the mid-4th millennium BCE (~3500 BCE), and to the early 2nd millennium BCE in China; elsewhere it gradually spread across regions. The Bronze Age was followed by the Iron Age, which started about 1300 BCE and reaching most of Eurasia by about 500 BCE, although bronze continued to be much more widely used than it is in modern times.

Falchion
A falchion (; Old French: ''fauchon''; Latin: ''falx'', "sickle") is a one-handed, backsword, single-edged sword of European origin. Falchions are found in different forms from around the 13th century up to and including the 16th century. In some versions, the falchion looks rather like the seax and later the sabre, and in other versions more like a machete with a crossguard. Types The blade designs of falchions varied widely across the continent and over time. They almost always included a single edge with a slight curve on the blade towards the point on the end and most were also affixed with a quilloned crossguard for the hilt in the manner of the contemporary arming swords. Unlike the double-edged swords of Europe, few actual swords of this type have survived to the present day; fewer than a dozen specimens are currently known. A number of weapons similar to the falchion existed in Western Europe, including the Messer (weapon), Messer, hanger (weapon), hanger and the backs ...

Obsidian
Obsidian ( ) is a naturally occurring volcanic glass formed when lava extrusive rock, extruded from a volcano cools rapidly with minimal crystal growth. It is an igneous rock. Produced from felsic lava, obsidian is rich in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. It is commonly found within the margins of rhyolite, rhyolitic lava flows known as obsidian flows. These flows have a high content of silicon dioxide, silica, giving them a high viscosity. The high viscosity inhibits the atomic diffusion, diffusion of atoms through the lava, which inhibits the first step (nucleation) in the formation of mineral crystals. Together with rapid cooling, this results in a natural glass forming from the lava. Obsidian is hard, Brittleness, brittle, and amorphous; it therefore Fracture (mineralogy)#Conchoidal fracture, fractures with sharp edges. In the past, it was used to manufacture cutting and piercing tools, and it has been used experimentally as s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
