Blade Geometry
The term ''blade geometry'' refers to the physical properties of a sword blade: cross-section (or grind) and taper. Cross-section The cross-section of a blade is the primary way of determining its function and place in history. Early Middle Ages Early Viking and medieval European blades tended to have a lenticular cross-section. This type of design lacks a strong central ridge in the middle of the blade. The flexibility these blades have illustrates the purpose that they served, as primarily cutting weapons, that could also be used with the thrust. Late Middle Ages With the improvement in the defensive capabilities of armor in the High and Late Middle Ages, the cross-section of the sword blade adapted to suit the needs of warriors. Swords began to favour rigidity over flexibility as more rigid blades allowed for the stronger thrusts that were used to pierce armour. These blades were made with a diamond cross-section, which could be more or less acute, depending on the purpose ...

Grind
A blade's grind is its cross-sectional shape in a plane normal to the edge. Grind differs from 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 the actual cutting edge of the blade itself, ...

Blade
A blade is the portion of a tool, weapon, or machine with an edge that is designed to puncture, chop, slice or scrape surfaces or materials. Blades are typically made from materials that are harder than those they are to be used on. Historically, humans have made blades from flaking stones such as flint or obsidian, and from various metal such as copper, bronze and iron. Modern blades are often made of steel or ceramic. Blades are one of humanity's oldest tools, and continue to be used for combat, food preparation, and other purposes. Blades work by concentrating force on the cutting edge. Certain blades, such as those used on bread knives or saws, are serrated, further concentrating force on the point of each tooth. Uses During food preparation, knives are mainly used for slicing, chopping, and piercing. In combat, a blade may be used to slash or puncture, and may also be thrown or otherwise propelled. The function is to sever a nerve, muscle or tendon fibers, or bloo ...

Viking
Vikings ; non, víkingr is the modern name given to seafaring people originally from Scandinavia (present-day Denmark, Norway and Sweden), who from the late 8th to the late 11th centuries raided, pirated, traded and settled throughout parts of Europe.Roesdahl, pp. 9–22. They also voyaged as far as the Mediterranean Sea, Mediterranean, North Africa, Volga Bulgaria, the Middle East, and Greenland, North America. In some of the countries they raided and settled in, this period is popularly known as the Viking Age, and the term "Viking" also commonly includes the inhabitants of the Scandinavian homelands as a collective whole. The Vikings had a profound impact on the Early Middle Ages, early medieval history of Scandinavia, the History of the British Isles, British Isles, France in the Middle Ages, France, Viking Age in Estonia, Estonia, and Kievan Rus'. Expert sailors and navigators aboard their characteristic longships, Vikings established Norse settlem ...

Armor
Armour (British English) or armor (American English; see spelling differences) is a covering used to protect an object, individual, or vehicle from physical injury or damage, especially direct contact weapons or projectiles during combat, or from a potentially dangerous environment or activity (e.g. cycling, construction sites, etc.). Personal armour is used to protect soldiers and war animals. Vehicle armour is used on warships, armoured fighting vehicles, and some mostly ground attack combat aircraft. A second use of the term ''armour'' describes armoured forces, armoured weapons, and their role in combat. After the development of armoured warfare, tanks and mechanised infantry and their combat formations came to be referred to collectively as "armour". Etymology The word "armour" began to appear in the Middle Ages as a derivative of Old French. It is dated from 1297 as a "mail, defensive covering worn in combat". The word originates from the Old French , itself derived ...

High Middle Ages
The High Middle Ages, or High Medieval Period, was the periodization, period of European history that lasted from AD 1000 to 1300. The High Middle Ages were preceded by the Early Middle Ages and were followed by the Late Middle Ages, which ended around AD 1500 (by historiography, historiographical convention). Key historical trends of the High Middle Ages include the medieval demography, rapidly increasing population of Europe, which brought about great social and political change from the preceding era, and the Renaissance of the 12th century, including the first developments of rural exodus and urbanization. By 1250, the robust population increase had greatly benefited the European economy, which reached levels that would not be seen again in some areas until the 19th century. That trend faltered during the Late Middle Ages because of a Crisis of the Late Middle Ages, series of calamities, most notably the Black Death, but also numerous wars as well as economic stagnation.

Estoc
The French estoc is a type of sword, also called a tuck in English, in use from the 14th to the 17th century. It is characterized by a cruciform hilt with a grip for two-handed use and a straight, edgeless, but sharply pointed blade of around to in length. It is noted for its ability to pierce mail armor. Description The estoc was a variation of the longsword designed for fighting against mail armour or plate armour. It was long, straight and stiff with no cutting edge, just a point. Examples from Poland are more than long, with a blade of ; however, others show a more manageable , with a blade. Such swords average about four pounds (2 kg) with no specimen weighing more than six pounds. Blade cross-sections can be triangular, square, rhomboid or flat hexagonal. This geometry leaves hardly any cutting capability as a sharpened edge could simply not be ground, but allowed the weapon to be lengthy, stiff, and very acutely pointed. Early on, the estoc was hung from the sad ...

Longsword
A longsword (also spelled as long sword or long-sword) is a type of European sword characterized as having a cruciform hilt with a grip for primarily two-handed use (around ), a straight double-edged blade of around , and weighing approximately . The "longsword" type exists in a morphological continuum with the medieval knightly sword and the Renaissance-era Zweihänder. It was prevalent during the late medieval and Renaissance periods (approximately 1350 to 1550), with early and late use reaching into the 12th and 17th centuries. Names English The longsword has many names in the English language, which, aside from variant spellings, include terms such as "bastard sword" and "hand-and-a-half sword." Of these, "bastard sword" is the oldest, its use being contemporaneous with the weapon's heyday. The French ' and the English "bastard sword" originate in the 15th or 16th century, originally in the general sense of "irregular sword, sword of uncertain origin", but by the mid ...
