Fuller (weapon)
A fuller is a rounded or beveled longitudinal groove or slot along the flat side of a blade (e.g., a sword, knife, or bayonet) that serves to both lighten and stiffen the blade, when considering its reduced weight. Cutting or grinding a fuller into an existing blade will decrease its absolute stiffness due to the removal of material, but much of the strength remains due to the geometry of its shape. When the groove is forged into the blade, it achieves a similar reduction in weight with a relatively small reduction in strength without the wasted material produced by grinding. When impressed during forging, it may be made using a blacksmithing tool that is also called a fuller, a form of spring swage. When combined with optimal} distal tapers, heat treatment and blade tempering, a fullered blade can be 20% to 35% lighter than a non-fullered blade. The ridges and groove created by the fuller are comparable to an I-beam's flanges and web; this shape aims to optimize the strength ...

Iris (plant)
''Iris'' is a flowering plant genus of 310 accepted species with showy flowers. As well as being the scientific name, iris is also widely used as a common name for all ''Iris'' species, as well as some belonging to other closely related genera. A common name for some species is flags, while the plants of the subgenus '' Scorpiris'' are widely known as junos, particularly in horticulture. It is a popular garden flower. The often-segregated, monotypic genera '' Belamcanda'' (blackberry lily, ''I. domestica''), '' Hermodactylus'' (snake's head iris, ''I. tuberosa''), and ''Pardanthopsis'' (vesper iris, '' I. dichotoma'') are currently included in ''Iris''. Three ''Iris'' varieties are used in the ''Iris'' flower data set outlined by Ronald Fisher in his 1936 paper ''The use of multiple measurements in taxonomic problems'' as an example of linear discriminant analysis. Description Irises are perennial plants, growing from creeping rhizomes (rhizomatous irises) or, in drier c ...

Fuller (metalworking)
In metalworking, a fuller is a tool used to shape hot metal. The fuller has a rounded nose, which may be either cylindrical or parabolicc. It may have a handle (an "upper fuller") or a shank (a "lower fuller"). The shank of the lower fuller allows insertion into the hardy hole of the anvil An anvil is a metalworking tool consisting of a large block of metal (usually Forging, forged or Steel casting, cast steel), with a flattened top surface, upon which another object is struck (or "worked"). Anvils are massive because the hi .... Upper fullers come in "straight" or "cross" varieties, depending on the handle's orientation relative to the face. The fuller is a forging tool used to spread metal. The fuller is placed against the metal stock. Either the fuller (for an upper fuller) or the stock (for a lower fuller) is then struck with a hammer. The fuller's rounded nose spreads the metal more efficiently than the flat face of a hammer. The process leaves ridges in the stock, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Fluted Armour
Maximilian armour is a modern term applied to the style of early 16th-century German plate armour associated with, and possibly first made for the Emperor Maximilian I. The armour is still white armour, made in plain steel, but it is decorated with many flutings that may also have played a role in deflecting the points and blades of assailants and increasing the structural strength of the plates. It is a transitional stage in the decoration of armour, after the plain steel surfaces of 15th-century armour and before the elaborate decoration and colouring with etching and other techniques of Renaissance armour. The armour is characterized by armets and close helmets with bellows visors; small fan-shaped narrow and parallel fluting—often covering most of the harness (but never the greaves); etching; work taken from woodcuts; sharply waisted cuirasses, and squared sabatons. According to an alternative version, the name is related to Maximilian II, as the last Maximilian armour wa ...

Corrugated Galvanised Iron
Corrugated galvanised iron (CGI) or steel, colloquially corrugated iron (near universal), wriggly tin (taken from UK military slang), pailing (in Caribbean English), corrugated sheet metal (in North America), zinc (in Cyprus and Nigeria) or custom orb / corro sheet (Australia), is a building material composed of sheets of hot-dip galvanizing, hot-dip galvanised mild steel, cold forming, cold-rolled to produce a linear ridged pattern in them. Although it is still popularly called "iron" in the UK, the material used is actually steel (which is iron alloyed with carbon for strength, commonly 0.3% carbon), and only the surviving vintage sheets may actually be made up of 100% iron. The corrugations increase the bending strength of the sheet in the direction perpendicular to the corrugations, but not parallel to them, because the steel must be stretched to bend perpendicular to the corrugations. Normally each sheet is manufactured longer in its strong direction. CGI is lightweight ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Lee–Enfield
The Lee–Enfield is a bolt-action, magazine-fed repeating rifle that served as the main firearm of the military forces of the British Empire and Commonwealth during the first half of the 20th century, and was the standard service rifle of the British Armed Forces from its official adoption in 1895 until 1957. A redesign of the Lee–Metford (adopted by the British Army in 1888), the Lee–Enfield superseded it and the earlier Martini–Henry and Martini–Enfield rifles. It featured a ten-round box magazine which was loaded with the .303 British cartridge manually from the top, either one round at a time or by means of five-round chargers. The Lee–Enfield was the standard-issue weapon to rifle companies of the British Army, colonial armies (such as India and parts of Africa), and other Commonwealth nations in both the First and Second World Wars (such as Australia, New Zealand, South Africa, and Canada). Although officially replaced in the United Kingdom with the L1A ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

SA80
The SA80 (Small Arms for the 1980s) is a British family of 5.56×45mm NATO service weapons used by the British Army. The L85 Rifle variant has been the standard issue service rifle of the British Armed Forces since 1987, replacing the L1A1 Self-Loading Rifle. The prototypes were created in 1976, with production of the A1 variant starting in 1985 and ending in 1994. The A2 variant came to be as the result of a significant upgrade in the early 2000s by Heckler & Koch and remains in service as of 2025. The A3 variant was first issued in 2018 with several new improvements. The remainder of the SA80 family consists of the L86 Light Support Weapon, the short-barrelled L22 Carbine and the L98 Cadet rifle. The SA80 was the last in a long line of British weapons (including the Lee–Enfield family) to come from the Royal Small Arms Factory, the national arms development and production facility at Enfield Lock, before its weapons factory was closed down in 1988.

World War One
World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a global conflict between two coalitions: the Allies (or Entente) and the Central Powers. Fighting took place mainly in Europe and the Middle East, as well as in parts of Africa and the Asia-Pacific, and in Europe was characterised by trench warfare; the widespread use of artillery, machine guns, and chemical weapons (gas); and the introductions of tanks and aircraft. World War I was one of the deadliest conflicts in history, resulting in an estimated 10 million military dead and more than 20 million wounded, plus some 10 million civilian dead from causes including genocide. The movement of large numbers of people was a major factor in the deadly Spanish flu pandemic. The causes of World War I included the rise of Germany and decline of the Ottoman Empire, which disturbed the long-standing balance of power in Europe, and rising economic competition between nation ...

Pattern 1907 Bayonet
The Pattern 1907 bayonet, officially called the Sword bayonet, pattern 1907 (Mark I), is an out-of-production British bayonet designed to be used with the Short Magazine Lee Enfield (SMLE) rifle. The Pattern 1907 bayonet was used by the British and Commonwealth forces throughout both the First World War, First and Second World Wars. Design The Pattern 1907 bayonet consists of a one-piece steel blade and Tang (tools), tang, with a crossguard and Pommel (sword), pommel made from wrought iron or mild steel, and a wooden Grip (sword), grip usually of walnut secured to the tang by two screws. The entire bayonet is long and weighs , although the weight of production models varied from . Bayonets produced before 1913 feature a hooked lower quillion intended for trapping an enemy's bayonet and possibly disarming opponents when grappling. This was later deemed impractical and replaced with a simpler design from 1913. Often unit armourers subsequently removed the hooked quillion when the ...

Grind
A blade's grind is its cross-sectional shape in a plane normal to the edge. Grind differs from Blade#Knife blade profiles .28Patterns.29, blade profile, which is the blade's cross-sectional shape in the plane containing the blade's edge and the centre contour of the blade's back (meaning the shape of the blade when viewed from the side, i.e. clip point, spear point, etc.). The ''grind'' of a blade should not be confused with the bevel forming the sharpened edge; it more usually describes the overall cross-section of the blade, not inclusive of the beveled cutting edge which is typically of a different, less acute angle as the bevel ground onto the blade to give it a cross-sectional shape. For example, the famous Buck 110 hunting knife has a "hollow ground" blade, with concave blade faces (which aid in slicing through materials), but the cutting edge itself is a simple, flat-ground bevel of lesser angle. It would be difficult, if not impossible, to put a "hollow grind" onto th ... [...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 ...
