A utility knife is any type of knife used for general manual work purposes. Such knives were originally fixed-blade knives with durable cutting edges suitable for rough work such as cutting cordage, cutting/scraping hides, butchering animals, cleaning fish scales, reshaping timber, and other tasks. Craft knives are small utility knives used as precision-oriented tools for finer, more delicate tasks such as carving and papercutting.
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 Originally made of wood, bone, and stone, over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have been made from copper, bronze,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.
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 butterfly knife, also known as a balisong, 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.
The Benchmade Knife Company is an American knife manufacturer in Oregon City, Oregon.
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 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. 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 briefly gained notoriety in the United States in the mid-1980s after they were 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.
Buck Knives is an American knife manufacturer founded in Mountain Home, Idaho and now located in Post Falls, Idaho. The company has a long history through five generations of the Buck family from 1902 to the present day. Buck Knives primarily manufactures sport and field knives and is credited with inventing the "folding hunting knife" and popularizing it to such a degree that the term "buck knife" has become synonymous with folding lockback knives, including those made by other manufacturers.
A trench knife is a combat knife designed to kill or incapacitate an enemy at close quarters, such as in a trench or other confined area. It was developed as a close combat weapon for soldiers attacking enemy trenches during the First World War. An example of a World War I trench knife is the German Army's Nahkampfmesser.
A pantographic knife or paratrooper knife is a folding knife whose blade is opened by a unique scissors method. The blade has a slightly longer tang than a folding knife heel. The handle is symmetrically segmented and articulated to fold away on both sides to grip the longer tang. The manner is similar to a butterfly knife —with which it is often confused. Unlike the balisong knife handles that swing freely and independently, the pantographic knife uses a pantograph linkage to keep the handles aligned during opening and closing. The mechanism includes a collar that travels up the blade. The pantographic knife is very strong when compared to most other folding knife designs, being joined at several points and along several planes—this increases the force required to break the blade away from the handle. By enclosing the blade on both sides, double edged blades can be used.
A latch or catch is a type of mechanical fastener that joins two objects or surfaces while allowing for their regular separation. A latch typically engages another piece of hardware on the other mounting surface. Depending upon the type and design of the latch, this engaged bit of hardware may be known as a keeper or strike.
Gerber Legendary Blades is an American maker of knives, multitools, and other tools for outdoors and military headquartered in Portland, Oregon. Gerber is owned by the Finnish outdoors products company Fiskars. Gerber was established in 1939 by Pete Gerber.
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.
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.
Imperial Schrade Corp. was an American knife manufacturer of hunting knives, pocketknives, utility knives, and bayonets during the 20th and early 21st centuries. The consolidation of five forerunner companies, including its namesakes, the Imperial Knife Company, founded 1916, and the Schrade Cutlery Company, founded in 1904, Imperial Schrade manufactured its products in the United States and Ireland and sold through hardware stores, department stores, and on military bases. The original company's fortunes declined and in 2004 it entered into bankruptcy where all equipment and intellectual property was sold off to reimburse creditors. The name and intellectual property was bought by Taylor Brands and used for marketing purposes.
The Mark I trench knife is an American trench knife designed by officers of the American Expeditionary Force (AEF) for use in World War I. It has a 6.75 in (17.1 cm) double-edged dagger blade useful for both thrusting and slashing strokes, unlike previous U.S. trench knives such as the M1917 and M1918. The handle is made of cast bronze and uses a conical steel nut to hold the blade in place. The Mark I's blade was blued with a black oxide finish, the bronze handle was chemically blackened, with cast spikes on the bow of each knuckle. The spikes were intended to prevent an opponent from grabbing the knife hand, as well as to provide a more concentrated striking surface when employed in hand-to-hand combat.
