Ballistic Knife
A ballistic knife is a knife with a detachable blade that can be ejected to a distance of several meters/yards by pressing a trigger or operating a lever or switch on the handle.Crawford, Steve, ''Deadly fighting skills of the world'', New York: Thomas Dunne Books, St. Martin's Press, (1999), pp. 45-46: The minimum standard demanded of ''Spetsnaz'' recruits when throwing a knife from six feet is three consecutive hits on target; five hits is considered excellent. Spring-powered ballistic knives first appeared in books and press reports on Soviet and Eastern Bloc armed forces in the late 1970s. Commercially-produced ballistic knives gained notoriety in the United States in the mid-1980s after being marketed and sold in the United States and other Western countries. Since then, the marketing and sale of ballistic knives to civilians has been restricted or prohibited by law in several nations. Usage In its spring-propelled form, the blade of a ballistic knife is theoretically capa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Knives
A knife (: knives; from Old Norse 'knife, dirk') 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 Originally made of wood, bone, and stone (such as flint and obsidian), over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have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. Knives can serve various purposes. Hunters use a hunting knife, soldiers use the combat knife, scouts, campers, and hikers carry a pocketknife; there are kitchen knives for preparing foods (the chef's knife, the paring knife, bread knife, cleaver), table knife ( butter knives and steak knives), weapons (daggers or switchblades), knives for throwing or juggli ...

Edged And Bladed Weapons
An edged weapon, or bladed weapon, is a hand-to-hand combat weapon with a cutting edge. Bladed weapons include swords, daggers, knives, and bayonets. Edged weapons are used to cut, hack, or slash; some edged weapons (such as many kinds of swords) may also permit thrusting and stabbing. Edged weapons contrast with blunt weapons such as maces, and with pointed weapons such as spears. Many edged agricultural tools such as machetes, hatchets, axes, sickles, sling blades, and scythes, have been used as improvised weapons by peasantry, militia, or irregular forces – particularly as an expedient for defence. Edged weapons and blades, as well as other cold weapons, are associated with the premodern age but continue to be used in modern armies. Combat knives and knife bayonets are used for close combat or stealth operations and are issued as a secondary or sidearm. Modern bayonets are often intended to be used in a dual role as both a combat knife and knife bayonet. Improvised ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Throwing Knife
A throwing knife is a knife that is specially designed and weighted so that it can be thrown effectively. They are a distinct category from ordinary knives. Throwing knives are used by many cultures around the world, and as such different tactics for throwing them have been developed, as have different shapes and forms of throwing knife. Throwing knives are also used in sideshow acts and sport. Central Africa Throwing knives saw use in central Africa. The wide area they were used over means that they were referred to by a number of names such as onzil, kulbeda, mambele (kpinga), and trombash. These weapons had multiple iron blades and were used for warfare and hunting. A maximum effective range of about has been suggested. The weapon appears to have originated in central Sudan somewhere around 1000 AD from where it spread south. It has however been suggested that the same weapon is depicted in Libyan wall sculptures dating around 1350 BC. The throwing knives were extensiv ...

Switchblade
A switchblade (also known as switch knife, automatic knife, pushbutton knife, ejector knife, flick knife, gravity knife, flick blade, or spring knife) 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, a means of preventing the blade from being accidentally closed while in the open position. An unlocking mechanism must be activated in order to close the blade for storage. During the 1950s, US newspapers as well as the tabloid press promoted the image of a new violent crime wave caused by young male delinquents with a switchblade or flick knife, based mostly on anecdotal evidence. In 1954, Democratic Rep. James J. Delaney of New York authored the first bill submitted to the U.S. Congress banning the manufacture and sale of switchblades, beginning a wave of legal restrictions worldwid ...

Pistol Sword
A pistol sword is a sword with a pistol or revolver attached, usually alongside the blade. It differs from a rifle with a bayonet attached, in that the weapon is designed primarily for use as a sword, and the firearm component is typically considered a secondary weapon designed to be an addition to the blade, rather than the sword being a secondary addition to the pistol. In addition, the two components of these weapons typically cannot be separated, unlike most bayonets mounted on rifles. History Historically, some flintlock pistols of the 17th and 18th centuries were constructed as gun-swords, with the barrel of the pistol attached to the side of the blade of a shortsword or dagger. A shell guard protected the firing mechanism when it was used as a sword. These were used by French and German hunters to kill wounded wild boar. Examples of these weapons can be found in the armoury of Wawel Castle (Kraków, Poland). Similar weapons were made in India, including the Katar (dagge ...

Knife Legislation
Knife legislation is defined as the legislation, 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. Carrying knives in public place, public is forbidden or restricted by law in many countries. Exceptions may be made for hunting knives, pocket knives, and knives used for work-related purposes (kitchen knife, chef's knives, etc.), depending upon the laws of a given jurisdiction. In turn, the carrying or possessing of certain types of knives perceived as deadly or offensive weapons, such as switchblade knives and Butterfly knife, butterfly knives, may be restricted or prohibited. Even where knives may be legally carried on the person generally, this right may not extend to all places and circumstances, and knives of any description may be prohibited at schools, public buildings, courthouse ...

Combination Weapons
In mathematics, a combination is a selection of items from a set that has distinct members, such that the order of selection does not matter (unlike permutations). For example, given three fruits, say an apple, an orange and a pear, there are three combinations of two that can be drawn from this set: an apple and a pear; an apple and an orange; or a pear and an orange. More formally, a ''k''-combination of a set ''S'' is a subset of ''k'' distinct elements of ''S''. So, two combinations are identical if and only if each combination has the same members. (The arrangement of the members in each set does not matter.) If the set has ''n'' elements, the number of ''k''-combinations, denoted by C(n,k) or C^n_k, is equal to the binomial coefficient \binom nk = \frac, which can be written using factorials as \textstyle\frac whenever k\leq n, and which is zero when k>n. This formula can be derived from the fact that each ''k''-combination of a set ''S'' of ''n'' members has k! permutati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prevention Of Crime Act 1953
The Prevention of Crime Act 1953 (1 & 2 Eliz. 2. c. 14) is an Acts of Parliament in the United Kingdom, 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 (the last year up to that point with such statistics) 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 (though carrying or using a weapon during the commission of a crime would earn a greater punishment) unless it was a firearm or imitation firearm. The Prevention of Crime Act was created under the pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Firearms Act
The National Firearms Act (NFA), 73rd Congress, Sess. 2, ch. 757, was enacted on June 26, 1934, and currently codified and amended as . The law is an Act of Congress in the United States that, in general, imposes an excise tax on the manufacture and transfer of certain firearms and mandates the registration of those firearms. The NFA is also referred to as Title II of the federal firearms laws, with the Gun Control Act of 1968 ("GCA") as Title I. All transfers of ownership of registered NFA firearms must be done through the National Firearms Registration and Transfer Record (the "NFA registry"). The NFA also requires that the permanent transport of NFA firearms across state lines by the owner must be reported to the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Temporary transports of some items, most notably suppressors (also referred to as silencers), do not need to be reported. Background The ostensible impetus for the National Firearms Act of 1934 was t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firearm
A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and operated by an individual. The term is legally defined further in different countries (see legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other explosive propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stabili ...
