Survival knives are knives intended for survival purposes in a wilderness environment, often in an emergency when the user has lost most of their main equipment. Most military aviation units issue some kind of survival knife to their pilots in case their aircraft are shot down behind enemy lines and the crew needs tools to facilitate their survival, escape, and rescue. [1] Survival knives can be used for trapping, skinning, wood cutting, wood carving, and other uses. Hunters, hikers, and outdoor sport enthusiasts use survival knives. Some survival knives are heavy-bladed and thick. Other survival knives are lightweight or fold in order to save weight and bulk as part of a larger survival kit. Their functions often include serving as a hunting knife. [2] Features, such as hollow handles, that could be used as storage space for matches or similar small items, began gaining popularity in the 1980s. [3] Custom or semi-custom makers such as Americans Gil Hibben, Jimmy Lile, Bo Randall, and Chris Reeve are often credited with inventing those features. [4] [5]
Prior to the late 19th century, outdoorsmen and military personnel did not use knives that were notably different from the knives used by butchers. Blades were relatively thin and the handles were often no more than two wooden slabs riveted to the tang. Serrations appeared on knives in the 19th century for use as a wood saw or fish scaler. [3] Around the turn of the century, Webster L. Marble introduced the modern concept of the "hunting knife." These knives incorporated heavier blades, crossguards, and pommels. They very much resembled miniaturized Bowie knives. Case, Cattaraugus, and other cutlery manufacturers soon introduced similar knives of their own and it is from these that the modern concept of the survival knife is descended. These knives, along with machetes and bolos constituted survival knives as used by military, explorers, and outdoorsmen up through at least the 1930s. [6]
During WWII, survival knives were issued to aircraft crew, as it was a real possibility that these personnel might be shot down over wilderness or behind enemy lines. Lifeboats aboard naval vessels also frequently contained survival kits including knives. These knives varied in design from one branch of the service to another and from one nation to another. The majority of them were simply commercial knives purchased in bulk by the military. From the Vietnam-era and to present, purpose-built survival knives evolved. [7] One of Randall's designs which became a popular fighting knife for troops in Vietnam was the Number 14 "Attack" Model. During Vietnam, Randall received feedback from a Combat Surgeon in the US Army's 94th Medical Detachment named Captain George Ingraham. Ingraham's request was for serrations on the spine to cut through the fuselage of downed aircraft to rescue trapped personnel and a hollow handle to allow storage of survival gear. Randall made the changes and the result was the first of the modern survival knives. [6]
Some militaries (including Finland, Germany, the People's Republic of China, the Soviet Union, the United Kingdom, and the United States) have redesigned the bayonet used with their issued rifle to include survival knife features. Historically, bayonets had functioned poorly as field knives, due to being designed primarily to turn a rifle into a thrusting weapon and only secondarily (if at all) to work as a field knife. The newer models function more acceptably for mundane tasks while remaining capable of being attached to the muzzle of a rifle. [8]
Survival knives are designed for work such as setting traps, cutting branches, carving wood, and skinning animals. Most survival knives have fixed blades that are 10 cm to 20 cm (3.9 - 7.9 inches) long with a full thick tang. Survival knives made by Aitor, Lile, Parrish, Randall, or Reeve have hollow handles, which allow the user to store additional equipment in the handle. Some of these knives feature a compass in the cap. A hollow handle survival knife may have reduced strength and may break more easily when performing tasks such as chopping or batoning.
On some survival knives, the spine or back of the blade is flat; allowing it to make a good hitting platform when pounding it with a hard stick to aid in splitting wood. Other models such as Lile's and Parrish's feature a serrated spine or in the case of Rob Simonich's and Strider Knives, a band (strapping) breaker near the tip. For survival knives that have a distinct flat spine with sharp 90 degree edges, the user can strike the spine edges against a ferrocerium rod to create sparks for fire starting purposes.
If the knife has a strong tip, then the knife can also be used as a weapon for self defense. Some knives even include holes in the handle such that the knife can be fastened to a long stick and then it functions as a spear tip. The capability to mount the knife on a stick to create a spear allows the user to better hunt wildlife at a safer distance.
The handle material of survival knives differs from one to the next and is determined primarily by user preference. Handle materials can be hardened rubber, wood, bone (horn), aluminium, polymer, or even metal, such as stainless steel in the case of the Aitor Jungle King I, or tool steel as used in the Chris Reeve One-Piece line. Makers like Lile, Strider, and Parrish often wrap these metal handled knives with cord which can be used in survival situations and in daily use provides a more comfortable and reliable grip. In a situation where the knife handle breaks, if the knife is full tang, users can also wrap the handle area of the tang with cord to create a functional makeshift handle and not lose the functionality of the knife.
The serrations seen on Aircrew Survival Egress Knife (ASEK) are intended to allow air crewmen to cut their way free through the relatively thin metal skin of a crashed helicopter or airplane. [3] Those knives that do include functional saw-teeth still suffer from lack of blade length, limiting the thickness of what can be cut when used as a saw. [3]
The AKM Type I bayonet (introduced in 1959) was a revolutionary design. [9] It has a Bowie style (clip-point) blade with saw-teeth along the spine, and can be used as a multi-purpose survival knife and wire-cutter when combined with its steel scabbard. [9] [10] This design was copied by other nations and formed the basis of the US M9 bayonet. [9] [11] The AK-74 bayonet 6Kh5 (introduced in 1983) represents a further refinement of the AKM bayonet. "It introduced a radical blade cross-section, that has a flat milled on one side near the edge and a corresponding flat milled on the opposite side near the false edge." [9] The blade has a new spear point and an improved one-piece moulded plastic grip, making it a more effective fighting knife. [9] It also has saw-teeth on the false edge and the usual hole for use as a wire-cutter. [9] The wire cutting versions of the AK bayonets each have an electrically insulated handle and an electrically insulated part of the scabbard, so it can be used to cut an electrified wire.
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 bayonet 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. The term is traditionally derived from Bayonne, the town in south-west France where bayonets were supposedly first used by Basques in the 17th century. 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 weapon of last resort, although it is still used for ceremonial purposes.
The kukri or khukuri is a type of short sword with a distinct recurve in its blade that originated in the Indian subcontinent. It serves multiple purposes as a melee weapon and also as a regular cutting tool throughout most of South Asia. The kukri, khukri, and kukkri spellings are of Indian English origin, with the original Nepalese English spelling being khukuri.
A blade is the sharp, cutting portion of a tool, weapon, or machine, specifically designed to puncture, chop, slice, or scrape surfaces or materials. Blades are typically made from materials that are harder than those they are intended to cut. This includes early examples made from flaked stones like flint or obsidian, evolving through the ages into metal forms like copper, bronze, and iron, and culminating in modern versions made from steel or ceramics. Serving as one of humanity's oldest tools, blades continue to have wide-ranging applications, including in combat, cooking, and various other everyday and specialized tasks.
A Japanese kitchen knife is a type of kitchen knife used for food preparation. These knives come in many different varieties and are often made using traditional Japanese blacksmithing techniques. They can be made from stainless steel, or hagane, which is the same kind of steel used to make Japanese swords. Most knives are referred to as hōchō or the variation -bōchō in compound words but can have other names including -kiri. There are four general categories used to distinguish the Japanese knife designs: handle, blade grind, steel, and construction.
A fuller is a rounded or beveled longitudinal groove or slot along the flat side of a blade that serves to both lighten and stiffen the blade, when considering its reduced weight.
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 kitchen knife is any knife that is intended to be used in food preparation. While much of this work can be accomplished with a few general-purpose knives – notably a large chef's knife, a tough cleaver, a small paring knife and some sort of serrated blade – there are also many specialized knives that are designed for specific tasks. Kitchen knives can be made from several different materials.
The Santoku bōchō or Bunka bōchō (文化包丁) is a general-purpose kitchen knife originating in Japan. Its blade is typically between 13 and 20 cm long, and has a flat edge and a sheepsfoot blade that curves down an angle approaching 60 degrees at the point. The term Santoku may refer to the wide variety of ingredients that the knife can handle: meat, fish and vegetables, or to the tasks it can perform: slicing, chopping and dicing, either interpretation indicating a multi-use, general-purpose kitchen knife. The Santoku's blade and handle are designed to work in harmony by matching the blade's width and weight to the weight of the tang and the handle.
A tang or shank is the back portion of the blade component of a tool where it extends into stock material or connects to a handle – as on a knife, sword, spear, arrowhead, chisel, file, coulter, pike, scythe, screwdriver, etc. One can classify various tang designs by their appearance, by the manner in which they attach to a handle, and by their length in relation to the handle.
The M9 bayonet, officially known as the M9 Phrobis III, is an American multi-purpose knife and bayonet officially adopted in 1986 by the United States Armed Forces for the M16 rifle. Featuring a 7-inch (18 cm) blade and issued with a sheath designed to double as a wire cutter, the M9 bayonet is designed to function not only as a combat knife but also as a multi-tool, capable of serving as a wire cutter, metal slicer, bottle opener, and screwdriver.
A serrated blade is one with a toothlike rather than a plain edge, and is used on saws and on some knives and scissors. It is also known as a dentated, sawtooth, or toothed blade. Most such blades are scalloped, having edges cut with curved notches, common on wood saws and bread knives.
The OKC-3S is a bayonet developed by the United States Marine Corps to replace the M7 bayonet and M9 bayonet as its service bayonet for the M16 family of rifles and M4 series carbine. This multipurpose bayonet provides greater durability than the M7 bayonet and it also functions as a fighting knife.
A combat knife is a fighting knife designed for military use and primarily intended for hand-to-hand or close combat fighting.

A fillet knife is a kitchen knife used for filleting. It gives good control and aids in filleting. It is a very flexible member of the boning knife family that is used to filet and prepare fish. Fillet knife blades are typically 15 to 28 cm long. This allows them to move easily along the backbone and under the skin of meat.
James Buel Lile, known as Jimmy Lile and "The Arkansas Knifesmith", was an American knifemaker from Russellville in Pope County, Arkansas, who made the Rambo Knife for the films First Blood and Rambo: First Blood Part II. As a knifemaker Lile served as a president of the Knifemakers' Guild and on the board of directors of the American Bladesmith Society.
A fighting knife has a blade designed to most effectively inflict injury in close-quarters physical confrontations. The combat knife and the trench knife are examples of military fighting knives.
