Blades Multi Plex
A blade is the 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 in material technolo ...

Exsanguination
Exsanguination is the loss of blood from the circulatory system of a vertebrate, usually leading to death. The word comes from the Latin 'sanguis', meaning blood, and the prefix 'ex-', meaning 'out of'. Exsanguination has long been used as a method of animal slaughter. Humane slaughter must ensure the animal is rendered insensible to pain, whether through a captive bolt or other process, prior to the bloodletting. Depending upon the health of the individual, a person usually dies from losing half to two-thirds of their blood; a loss of roughly one-third of the blood volume is Critical condition, considered very serious. Even a single deep cut can warrant Surgical suture, suturing and Inpatient care, hospitalization, especially if Trauma (medicine), trauma, a vein or artery, or another comorbidity is involved. In the past, bloodletting was a common medical procedure or therapy, now rarely used in medicine. Slaughtering of animals Exsanguination is used as a Animal slaughter, s ...

Elastic Modulus
An elastic modulus (also known as modulus of elasticity (MOE)) is a quantity that describes an object's or substance's resistance to being deformed elastically (i.e., non-permanently) when a stress is applied to it. Definition The elastic modulus of an object is defined as the slope of its stress–strain curve in the elastic deformation region: A stiffer material will have a higher elastic modulus. An elastic modulus has the form: :\delta \ \stackrel\ \frac where stress is the force causing the deformation divided by the area to which the force is applied and strain is the ratio of the change in some parameter caused by the deformation to the original value of the parameter. Since strain is a dimensionless quantity, the units of \delta will be the same as the units of stress. Elastic constants and moduli Elastic constants are specific parameters that quantify the stiffness of a material in response to applied stresses and are fundamental in defining the elastic pr ...

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 ...
