Steel
Steel is an alloy of iron and carbon with improved strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels, which are resistant to corrosion and oxidation, typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, bicycles, machines, electrical appliances, furniture, and weapons. Iron is the base metal of steel.
Sword
A sword is an edged, bladed weapon intended for manual cutting or thrusting. Its blade, longer than a knife or dagger, is attached to a hilt and can be straight or curved. A thrusting sword tends to have a straighter blade with a pointed tip. A slashing sword is more likely to be curved and to have a sharpened cutting edge on one or both sides of the blade. Many swords are designed for both thrusting and slashing. The precise definition of a sword varies by historical epoch and geographic region.
Dagger
A dagger is a fighting knife with a very sharp point and usually two sharp edges, typically designed or capable of being used as a thrusting or stabbing weapon. Daggers have been used throughout human history for close combat confrontations, and many cultures have used adorned daggers in ritual and ceremonial contexts. The distinctive shape and historic usage of the dagger have made it iconic and symbolic. A dagger in the modern sense is a weapon designed for close-proximity combat or self-defense; due to its use in historic weapon assemblages, it has associations with assassination and murders.
Weapon
A weapon, arm or armament is any implement or device that is used to deter, threaten, inflict physical damage, harm, or kill. Weapons are used to increase the efficacy and efficiency of activities such as hunting, crime, law enforcement, self-defense, warfare, or suicide. In broader context, weapons may be construed to include anything used to gain a tactical, strategic, material or mental advantage over an adversary or enemy target.
Bowie knife
A Bowie knife (ˈbuːi ) is a pattern of fixed-blade fighting knife created by Rezin Bowie in the early 19th century for his brother Jim Bowie, who had become famous for his use of a large knife at a duel known as the Sandbar Fight. Since the first incarnation, the Bowie knife has come to incorporate several recognizable and characteristic design features, although in common usage the term refers to any large sheath knife with a crossguard and a clip point.
Combat knife
A combat knife is a fighting knife designed for military use and primarily intended for hand-to-hand or close combat fighting. Since the end of trench warfare, most military combat knives have been secondarily designed for utility use (clearing foliage, chopping branches for cover, opening ammunition crates, etc.) in addition to their original role as close-quarter combat weapons, and may be referred to as "fighting-utility knives.
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.
Bayonet
A bayonet (from French baïonnette) is a knife, dagger, sword, or spike-shaped weapon designed to fit on the end of the muzzle of a rifle, carbine, musket or similar firearm, allowing it to be used as a spear-like weapon. From the early 17th to the early 20th century, it was a melee weapon used by infantry for offensive and/or defensive tactics. Today, it is considered an ancillary weapon or a weapon of last resort, although it is still used for ceremonial purposes.
Stiletto
A stiletto (plural stilettos) is a specialized knife or dagger with a long slender blade and needle-like point, primarily intended as a thrusting and stabbing weapon. The stiletto blade's narrow cross-section and acuminated tip (that is, a tip which tapers to a sharp point) reduce friction upon entry, allowing the blade to penetrate deeply. Some consider the stiletto a form of dagger, but most stilettos are specialized thrusting weapons not designed for cutting or slashing, even with edged examples.
Forging
Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer (often a power hammer) or a die. Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working), warm forging, or hot forging (a type of hot working). For the latter two, the metal is heated, usually in a forge. Forged parts can range in weight from less than a kilogram to hundreds of metric tons.
