A knife is a tool or weapon with a cutting edge or blade, usually attached to a handle or hilt. One of the earliest tools used by humanity, knives appeared at least 2.5 million years ago, as evidenced by the Oldowan tools. Originally made of wood, bone, and stone, over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have been made from copper, bronze, iron, steel, ceramic, and titanium. Most modern knives have either fixed or folding blades; blade patterns and styles vary by maker and country of origin.
The right to keep and bear arms is a legal right for people to possess weapons (arms) for the preservation of life, liberty, and property. The purpose of gun rights is for self-defense, as well as hunting and sporting activities. Countries that guarantee the right to keep and bear arms include Albania, Czech Republic, Guatemala, Ukraine, Mexico, the United States, Yemen, and Switzerland.
Brass knuckles are a melee weapon used primarily in hand-to-hand combat. They are fitted and designed to be worn around the knuckles of the human hand. Despite their name, they are often made from other metals, plastics or carbon fibers and not necessarily brass.
A switchblade is a pocketknife with a sliding or pivoting blade contained in the handle which is extended automatically by a spring when a button, lever, or switch on the handle or bolster is activated. Virtually all switchblades incorporate a locking blade, where the blade is locked against accidental closure when the blade is in the open position. It is unlocked by a mechanism that allows the blade to be folded and locked in the closed position.
A balisong, also known as a butterfly knife, fan knife or Batangas knife, is a type of folding pocketknife that originated in the Philippines. Its distinct features are two handles counter-rotating around the tang such that, when closed, the blade is concealed within grooves in the handles. A latch sometimes holds the handles together; typically mounted on the one facing the cutting edge.
A stiletto is a specialized dagger with a long slender blade and needle-like point, primarily intended as a thrusting and stabbing weapon.
A pocketknife is a knife with one or more blades that fold into the handle. They are also known as jackknives (jack-knife), folding knives, EDC knife, or may be referred to as a penknife, though a penknife may also be a specific kind of pocketknife. A typical blade length is 5 to 15 centimetres.
A gravity knife is a knife with a blade contained in its handle, and that opens its blade through the force of gravity. This mechanism of opening is fundamentally different from the switchblade, which extends its spring-propelled blade automatically upon the push of a button, switch, or fulcrum lever. The main purpose of gravity opening is that it allows opening and closing to be done one handed, in situations where the other hand is occupied. Hence, historically they have been issued to parachutists to cut off caught lines, such as lines tangled in trees, a major potential use of the gravity knife.
A swordstick or cane-sword is a cane containing a hidden blade or sword. The term is typically used to describe European weapons from around the 18th century. But similar devices have been used throughout history, notably the Roman dolon, the Japanese shikomizue and the Indian gupti.
An assisted-opening knife is a type of folding knife which uses an internal mechanism to finish the opening of the blade once the user has partially opened it using a flipper or thumbstud attached to the blade.
Concealed carry, or carrying a concealed weapon (CCW), is the practice of carrying a weapon, either in proximity to or on one's person or in public places in a manner that hides or conceals the weapon's presence from surrounding observers. In the United States, the opposite of concealed carry is called open carry.
In the United States, the right to keep and bear arms is modulated by a variety of state and federal statutes. These laws generally regulate the manufacture, trade, possession, transfer, record keeping, transport, and destruction of firearms, ammunition, and firearms accessories. They are enforced by state, local and the federal agencies which include the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).
Knife legislation is defined as the body of statutory law or case law promulgated or enacted by a government or other governing jurisdiction that prohibits, criminalizes, or restricts the otherwise legal manufacture, importation, sale, transfer, possession, transport, or use of knives.
An offensive weapon is a tool made, adapted or intended for the purpose of inflicting physical injury upon another person.
Weighted-knuckle gloves, also called sap gloves, are a type of handwear-concealed melee weapon used in hand-to-hand combat, consisting of a pair of ordinary-looking impact protection gloves usually made of leather or a synthetic material, with powdered lead or steel sewn into a special pouch covering the knuckles, and often also the backs of the fingers and the hand. In some designs, this distinctive feature is obvious, while in others it is almost completely indistinguishable from an ordinary glove, allowing the gloves to be worn in plain sight without suspicion.
The Prevention of Crime Act 1953 is an Act of the Parliament of the United Kingdom that restricts the carrying of offensive weapons in public. The Act was passed in response to the large rise in violent crime in the United Kingdom, with 800 cases of armed robbery, assault with intent to rob or robbery with violence and 4,445 cases of malicious wounding in 1951 while many of these crimes did not include the use of weapons there were calls from politicians, police officers and members of the public for new laws to combat the problem by restricting civilian weapons. Prior to the act it was not a crime to carry a weapon in a public place for offensive or defensive purposes unless it was a firearm or imitation firearm. The Prevention of Crime Act was created to under the presumption that banning weapons from all civilians, regardless of their intention, from public places would reduce violent crime, receiving royal assent on 6 May 1953 and coming into force on 6 June. No subsequent studies were carried out afterwards to ascertain what effect, if any, the act had on crime.
Criminal possession of a weapon is the unlawful possession of a weapon by an individual. It may also be an additional crime if a violent offense was committed with a deadly weapon or firearm.
The Arms Act, 1959 is an Act of the Parliament of India to consolidate and amend the law relating to arms and ammunition in order to curb illegal weapons and violence stemming from them. It replaced the Indian Arms Act, 1878.
A zombie knife is a type of ornate knife or bladed weapon inspired by zombie films and TV series. These knives can range in size and shape but are commonly defined as having a cutting edge, a serrated edge and images or words that suggest that it is to be used for the purpose of violence. Despite being designed for collectors and survivalists, the appearance of zombie knives led to their increasing usage in criminality. In 2016, parts of the United Kingdom made the sale of such knives illegal but with exceptions. In January 2024, the UK Government made the selling of zombie knives illegal without exceptions.
The Offensive Weapons Act 2019 is an act of the Parliament of the United Kingdom. The act addresses crimes related to acid attacks ; knife crime prevention orders; the sale of, delivery and possession of knives and other offensive weapons; and introduced further restrictions on firearms. It was introduced to Parliament as a government bill by Sajid Javid and Baroness Williams of Trafford of the Home Office.
