A sharp-edged instrument used for cutting, peeling, slicing, spreading and so on. Most knife blades are made of steel, but a material called ceramic zirconia is now also being used. It reportedly won't rust, corrode or interact with food and is reputed to be second only to the diamond in hardness. Knife handles can be one of many materials including wood, plastic-impregnated wood, plastic, horn and metal. The blade should be forged carbon or high-carbon stainless steel that resists stains and rust and gives an excellent cutting edge. A good knife should be sturdy and well balanced. In the best knives, the end of the blade (called the tang) extends all the way to the end of the handle, where it's anchored by several rivets. Knives come in a variety of different sizes and shapes-each with its own specific use. A French knife (also called chef's knife), with its broad, tapered shape and fine edge is perfect for chopping vegetables, while the slicing knife cuts cleanly through cooked meat with its long, thin, narrow blade. Knives with serrated or scalloped edges make neat work of slicing softer foods such as bread, tomatoes and cake. The pointed, short-bladed paring knife is easy to handle and makes quick work of peeling, removing cores, etc. Knives used for table service are usually named after their use, such as dinner, luncheon, fish, butter and steak knives.
Knives come in all shapes and sizes, but for many of the purposes for which an undercover operative might need one, small is preferred; hence, the plethora of diminutive edge weapons available to persons working covert operations for a well-supplied organization such as the Central Intelligence Agency (CIA). Knives may be used for escape and related applications such as lock-picking, or—more infamously—to inflict personal harm. For the latter application, where assassination is the intent, concealment is key, and small daggers (a smaller instrument, made purely for stabbing) are favored. Other knives are made for close combat, in which case a longer blade offers an advantage.
Small knives for concealment. At the extremely small end are thumb knives, lapel daggers, coin knives, and the like. Developed by the British in World War II, the coin knife looks like an ordinary piece of pocket change, which makes it easy for a prisoner to keep it on his person, even after being searched. The blade itself is crescent-shaped, and attaches to the back by a small hasp so that it can rotate outward. It is too blunt to be used for inflicting bodily harm, but can be useful in escape. The inside of the blade is much sharper, after the manner of a cigar cutter, and was sometimes used to slice through the tire stems on German vehicles during the war. The British favored their one-pence piece, though any large coin would serve the purpose.
A similar concept is the ring knife, whose blade is much sharper than that of the coin knife, and not retractable. To conceal its purpose, users hide the curved blade on the inside of the hand until it is needed, at which point the ring can be turned around and used. Lapel daggers, also used widely by the Allies and Resistance in World War II, resemble thumb knives. (The latter are discussed elsewhere, in the context of assassination weapons.) Very sharp and short, the lapel dagger often had a hole at one end, through which passed a loop to attach it to the forefinger so as to ensure greater control when using it. Originally these weapons really were concealed in lapels, but after the Germans became aware of this practice, agents found other places to hide them, including in the lining of their clothes. Some hid them in their socks after the style of the kilted Scottish warriors, whose shen du had been the model for the lapel dagger.
Long knives for power. Knives and daggers have been concealed in belts (that is, on the inside of the belt and parallel to it), in belt buckles, and even in the plastic arms of eyeglasses. But when the user is going into a situation of open combat, and concealment is not necessary, a large knife is desirable. An example is the throwing knife, which looks like an elongated spear point (though with the flanges rounded off) along with about six inches of the "spear" itself as a grip. It is very thin, which makes it easy to throw, but in order to be effective, it must be thrown with both accuracy and power, and throwing must be followed by one or more thrusts at close quarters.
Most formidable-looking of all is the Fairbairn-Sykes fighting knife, developed in World War II by two British officers, W. E. Fairbairn and E. A. Sykes. Based on knowledge gained from their experience in close combat while serving with the Shanghai police, the knife would quickly dispatch a victim by striking at his vital organs. Its blade was long, but the handle was nearly as lengthy, so as to ensure great control on the part of the user. First produced in 1941, it was readily adopted by the Allies. British commandoes carried it on raids into Norway, and the United States Office of Strategic Services (OSS), which employed Fairbairn as an instructor, developed its own version. Revised over the years, the knife remained in production through the 1990s.

A single-bladed cutting instrument other than a scalpel and usually designed for a special purpose.
- castrating k. — there are many straight bladed instruments available. A special hooked knife is popular for use with calves and lambs. It has a cutting edge which is bent down at right angles to form a shallow hook. The instrument is drawn towards the operator and provides much less risk to him/her. See also Newberry castrating knife (below).
- drawing k. — see hoof knife (below).
- finger k. — used in bovine obstetrics to cut the skin of a dead fetus. It consists of a flat palm-piece that lies flat against the palm of the hand and from which the hooked knife protrudes. The knife has a single finger ring on its spine, through which a finger is passed and over the front of the knife. The knife is passed into the uterus, and hooked into appropriate skin, which is cut by pulling backwards. Some knives have an eyelet to which a cord can be attached to facilitate this part of the task.
- hoof k. — a strong, slightly curved knife with its tip turned laterally on itself to form a tunnel. The flat part of the blade is used to trim the bottom of the hoof wall and the curved part to make grooves or cut holes. The standard knife is the Hauptner. The blade in some knives is sharpened on both edges. Called also hoof parer, drawing knife. — The Swiss hoof knife is a large, flattened loop turned down at right angles to the handle. It is for paring the sole and is drawn towards the operator with the lower front-edge sharpened. Special grooving knives are also available. See also Hughes hoof groover.
- Lichty's teat k. — a narrow, 0.1 inch wide blade about 0.4 inch long, sharpened on one edge and with a rounded blunt point, which is inserted into the teat canal. A cut is made laterally through the overtight sphincter or scar tissue.
- Newberry castrating k. — a pincer-like instrument with a block at the end of one blade and a chisel-pointed knife on the other. When the sharp blade is closed on the exposed spermatic cord, it compresses the cord against the block.
- palm k. — a small version of the Stanley hobby knife, which can be carried into the uterus in the palm of the hand and the concealed blade opened. Cuts are made in the fetal skin in a normal cutting manner.
- tenotomy k. — has a blunt, rounded tip on the blade, which is curved slightly forward so that the knife can be inserted under the tendon without damage to local nerves and blood vessels and so that a cut can be made outwards without the tendon slipping off the knife. Called also a tenotome.
- Wamberg spavin k. — used for transecting the cunean tendon in a horse affected by spavin. Has a 1.5 inch blade on a curved neck so that the blade can be inserted under the tendon without being obstructed by the knuckles of the hand holding the handle.

For other uses, see Knife (disambiguation).
A knife (plural knives) is a cutting tool with an exposed cutting edge or blade, hand-held or otherwise, with or without a handle. Knife-like tools were used at least two-and-a-half million years ago, as evidenced by the Oldowan tools.[1][2] Originally made of rock, flint, and obsidian, knives have evolved in construction as technology has, with blades being made from bronze, copper, iron, steel, ceramics, and titanium. Many cultures have their unique version of the knife. Due to its role as humankind's first tool, certain cultures have attached spiritual and religious significance to the knife.[3]
Most modern-day knives follow either a fixed-blade or a folding construction style, with blade patterns and styles as varied as their makers and countries of origin.

Materials, features, and construction
Main article: Knife making
Today, knives come in many forms but can be generally categorized between two broad types: fixed blade knives and folding, or pocket knives.
Parts of a knife
Modern knives consist of a blade (1) and handle (2). The blade edge can be plain or serrated or a combination of both. The handle, used to grip and manipulate the blade safely, may include the tang, a portion of the blade that extends into the handle. Knives are made with partial tangs (extending part way into the handle, known as a "Stick Tang") or full tangs (extending the full length of the handle, often visible on top and bottom). The handle can include a bolster, which is a piece of material used to balance the knife, usually brass or other metal, at the front of the handle where it meets the blade. The blade consists of (3) the point – the end of the knife used for piercing; (4) the edge – the cutting surface of the knife extending from the point to the heel; (5), the grind, the cross section shape of the blade; (6) the spine – the thickest section of the blade; (7), the fuller, the groove added to lighten the blade; (8) the ricasso, the flat section of the blade located at the junction of the blade and the knife's bolster or guard; (9) the guard, the barrier between the blade and the handle which prevents the hand from slipping forward onto the blade, and (10) the end of the handle, or butt. A choil, where the blade is unsharpened and possibly indented as it meets the handle, may be used to prevent scratches to the handle when sharpening or as a forward-finger grip. The knife's handle or butt may allow a lanyard (11) to be used to secure the knife to the wrist, or a portion of the tang to protrude as a striking surface for hitting or glass breaking.[4] Single edged knives may uitilze a reverse edge or false edge, in which the forward section of the knife's spine (opposing the sharpened edge) is thinned and left unsharpened.
Blade
Main article: Blade
Knife blades can be manufactured from a variety of materials, each of which has advantages and disadvantages. Carbon steel, an alloy of iron and carbon, can be very sharp, hold its edge well, and remain easy to sharpen, but is vulnerable to rust and stains. Stainless steel is an alloy of iron, chromium, possibly nickel, and molybdenum, with only a small amount of carbon. It is not able to take quite as sharp an edge as carbon steel, but is highly resistant to corrosion. High carbon stainless steel is stainless steel with a higher amount of carbon, intended to incorporate the better attributes of carbon steel and stainless steel. High carbon stainless steel blades do not discolor or stain, and maintain a sharp edge. Laminate blades use multiple metals to create a layered sandwich, combining the attributes of both. For example, a harder, more brittle steel may be sandwiched between an outer layer of softer, tougher, stainless steel to reduce vulnerability to corrosion. In this case, however, the part most affected by corrosion, the edge, is still vulnerable. Pattern-welding is similar to laminate construction. Layers of different steel types are welded together, but then the stock is manipulated to create patterns in the steel. Titanium is a metal that has a better strength-to-weight ratio, is more wear resistant, and more flexible than steel. Although less hard and unable to take as sharp an edge, carbides in the titanium alloy allow them to be heat-treated to a sufficient hardness. Ceramic blades are hard, brittle, and lightweight: they may maintain a sharp edge for years with no maintenance at all, but are as fragile as glass and will break if dropped on a hard surface. They are immune to common corrosion, and can only be sharpened on silicon carbide sandpaper and some grinding wheels. Plastic blades are not especially sharp and typically serrated. They are often disposable.[5]
Steel blades are commonly shaped by forging or stock removal. Forged blades are made by heating a single piece of steel, then shaping the metal while hot using a hammer or press. Stock removal blades are shaped by grinding and removing metal. With both methods, after shaping, the steel must be heat treated. This involves heating the steel above its critical point, then quenching the blade to harden it. After hardening, the blade is tempered to remove stresses and make the blade tougher. Mass manufactured kitchen cutlery uses both the forging and stock removal processes. Forging tends to be reserved for manufacturers' more expensive product lines, and can often be distinguished from stock removal product lines by the presence of an integral bolster, though integral bolsters can be crafted through either shaping method.
Knives are sharpened in various ways. Flat ground blades have a profile that tapers from the thick spine to the sharp edge in a straight or convex line. Seen in cross section, the blade would form a long, thin triangle, or where the taper does not extend to the back of the blade, a long thin rectangle with one peaked side. Hollow ground blades have concave, beveled edges. The resulting blade has a thinner edge, so it may have better cutting ability for shallow cuts, but it is lighter and less durable than flat ground blades and will tend to bind in deep cuts.[citation needed] Serrated blade knives have a wavy, scalloped or saw-like blade. Serrated blades are more well suited for tasks that require aggressive 'sawing' motions, whereas plain edge blades are better suited for tasks that require push-through cuts (e.g., shaving, chopping, slicing).
Fixed blade features
A fixed blade knife, sometimes called a sheath knife, does not fold or slide, and is typically stronger due to the tang, the extension of the blade into the handle, and lack of moving parts.
Folding blade features
Main article: Pocket knife
A folding knife connects the blade to the handle through a pivot, allowing the blade to fold into the handle. To prevent injury to the knife user through the blade accidentally closing on the user's hand, folding knives typically have a locking mechanism. Different locking mechanisms are favored by various individuals for reasons such as perceived strength (lock safety), legality, and ease of use. Popular locking mechanisms include:
- Slip joint – Found most commonly on traditional pocket knives, the opened blade does not lock, but is held in place by a spring device that allows the blade to fold if a certain amount of pressure is applied.
- Lockback – Also known as the spine lock, the lockback includes a pivoted latch affixed to a spring, and can be disengaged only by pressing the latch down to release the blade.[5]
- Liner Lock – Invented by Michael Walker, uses a leaf spring-type liner within the groove of the handle that snaps into position under the blade when it is deployed. The lock is released by pushing the liner to the side, to allow the blade to return to its groove set into the handle.
- Compression Lock – A variant of the Liner Lock, it uses a small piece of metal at the tip of the lock to lock into a small corresponding impression in the blade. This creates a lock that doesn't disengage when the blade is torqued, instead becoming more tightly locked. It is released by pressing the tab of metal to the side, to allow the blade to be placed into its grove set into the handle.
- Frame Lock – Also known as the integral lock or monolock, this locking mechanism was invented by custom knifemaker Chris Reeve for the Sebenza as an update to the liner lock. The frame lock works in a manner similar to the liner lock but uses a partial cutout of the actual knife handle, rather than a separate liner inside the handle to hold the blade in place.
- Collar lock – found on Opinel knives
- Button Lock – Found mainly on automatic knives, this type of lock uses a small push-button to open and release the knife.
The Benchmade Axis Lock mechanism
- Axis Lock – A locking mechanism exclusively licensed to the Benchmade Knife Company
- Arc Lock – A locking mechanism exclusively licensed to SOG Specialty Knives.
- Tri-Ad Lock – A locking mechanism exclusively licensed to Cold Steel.
- PickLock – A round post on the back base of the blade locks into a hole in a spring tab in the handle. To close, manually lift (pick) the spring tab (lock) off the blade post with your fingers, or in "Italian Style Stilettos" swivel the bolster (hand guard) clockwise to lift the spring tab off the blade post.
Another prominent feature on many folding knives is the opening mechanism. Traditional pocket knives and Swiss Army Knives commonly employ the nail nick, while modern folding knives more often use a stud, hole, disk, or flipper located on the blade, all which have the benefit of allowing the user to open the knife with one hand. The wave feature is another prominent design, which uses a part of the blade that protrudes outward to catch on one's pocket as it is drawn, thus opening the blade; this was patented by Ernest Emerson and is not only used on many of the Emerson knives, but also on knives produced by Spyderco and Cold Steel as well.
Automatic or switchblade knives open using the stored energy from a spring that is released when the user presses a button or lever or other actuator built into the handle of the knife. Automatic knives are popular amongst law enforcement and military users for their ease of rapid deployment and their ability to be opened using only one hand.[citation needed] Automatic knives are severely restricted by law in most American states.[6]
Increasingly common are assisted opening knives which use springs to propel the blade once the user has moved it past a certain angle. These differ from automatic or switchblade knives in that the blade is not released by means of a button or catch on the handle; rather, the blade itself is the actuator. Most assisted openers use flippers as their opening mechanism. Assisted opening knives can be as fast or faster than automatic knives to deploy.
Sliding blade features
Main article: Sliding knife
A sliding knife is a knife which can be opened by sliding the knife blade out the front of the handle. One method of opening is where the blade exits out the front of the handle point-first and then is locked into place (an example of this is the gravity knife). Another form is an O-T-F (out-the-front) switchblade, which only requires the push of a button or spring to cause the blade to slide out of the handle, and lock into place. To retract the blade back into the handle, a release lever or button, usually the same control as to open, is pressed. A very common form of sliding knife is the sliding utility knife (commonly known as a stanley knife or boxcutter).
Handle
Main article: Handle (grip)
The handles of knives can be made from a number of different materials, each of which has advantages and disadvantages. Handles are produced in a wide variety of shapes and styles. Handles are often textured to enhance grip.
- Wood handles provide good grip and are warm in the hand, but are more difficult to care for. They do not resist water well, and will crack or warp with prolonged exposure to water. Modern stabilized and laminated woods have largely overcome these problems. Many beautiful and exotic hardwoods are employed in the manufacture of custom and some production knives. In some countries it is now forbidden for commercial butchers' knives to have wood handles, for sanitary reasons.[citation needed]
- Plastic handles are more easily cared for than wooden handles, but can be slippery and become brittle over time.[3]
- Injection molded handles made from higher grade plastics are composed of Polyphthalamide, and when marketed under trademarked names such as Zytel or Grivory, are reinforced with Kevlar or fiberglass. These are often used by major knife manufacturers.
- Rubber handles such as Kraton or Resiprene-C are generally preferred over plastic due to their durable and cushioning nature.
- Micarta is a popular handle material on user knives due to its toughness and stability. Micarta is nearly impervious to water, is grippy when wet, and is an excellent insulator. Micarta has come to refer to any fibrous material cast in resin. There are many varieties of micarta available. One very popular version is a fiberglass impregnated resin called G-10.
- Leather handles are seen on some hunting and military knives, notably the KA-BAR. Leather handles are typically produced by stacking leather washers, or less commonly, as a sleeve surrounding another handle material.
- Skeleton handles refers to the practice of using the tang itself as the handle, usually with sections of material removed to reduce weight. Skeleton handled knives are often wrapped with parachute cord or other wrapping materials to enhance grip.
- Stainless steel and Aluminum handles are durable and sanitary, but can be slippery. To counter this, premium knife makers make handles with ridges, bumps, or indentations to provide extra grip. Another problem with knives that have metal handles is that, since metal is an excellent heat-conductor, these knives can be very uncomfortable, and even painful or dangerous, when handled without gloves or other protective handwear in (very) cold climates.
More exotic materials usually only seen on art or ceremonial knives include: Stone, bone, mammoth tooth, mammoth ivory, oosik (walrus penis bone), walrus tusk, antler (often called stag in a knife context), sheep horn, buffalo horn, teeth, mop (mother of pearl or "pearl") etc. Many materials have been employed in knife handles.
Types of knives

Rituals and superstitions
The knife plays a significant role in some cultures through ritual and superstition, as the knife was an essential tool for survival since early man.[2] Knife symbols can be found in various cultures to symbolize all stages of life; for example, a knife placed under the bed while giving birth is said to ease the pain, or, stuck into the headboard of a cradle, to protect the baby;[7][8] knives were included in some Anglo-Saxon burial rites, so the dead would not be defenseless in the next world.[9][10][11] The knife plays an important role in some initiation rites, and many cultures perform rituals with a variety of knives, including the ceremonial sacrifices of animals.[12] Samurai warriors, as part of bushido, could perform ritual suicide, or seppuku, with a tantō, a common Japanese knife.[13] An athame, a ceremonial black-handled knife, is used in Wicca and derived forms of neopagan witchcraft.[14][15]
In Greece a black-handled knife placed under the pillow is used to keep away nightmares.[16] As early as 1646 reference is made to a superstition of laying a knife across another piece of cutlery being a sign of witchcraft.[17] A common belief is that if a knife is given as a gift, the relationship of the giver and recipient will be severed. Something such as a small coin, dove or a valuable item is exchanged for the gift, rendering "payment."[8]
Legislation
Main article: Knife legislation
Knives are typically restricted by law, although restrictions vary greatly by country or state and type of knife. For example, some laws restrict carrying knives in public while other laws restrict private ownership of certain knives, such as switchblades.
