, is a military fighting knife.

Fighting knives were traditionally designed as special-purpose weapons, intended primarily if not solely for use in personal or hand-to-hand combat. This singularity of purpose originally distinguished the fighting knife from the field knife, fighting utility knife, or in modern usage, the tactical knife. The tactical knife is a knife with one or more military features designed for use in extreme situations, which may or may not include a design capability as a fighting or combat weapon. Since World War I, the fighting knife in military service has gradually evolved into a dual-purpose or "fighting-utility" knife, suited for both knife fighting and utility roles. As a consequence, the terms "fighting knife" and "tactical knife" are frequently employed interchangeably.

Antiquity

Utility knives with stone or flint blades were undoubtedly used in personal combat since Neolithic times.
One of the earliest metal-blade fighting knives was the dagger

 blade was recovered from the Sillees River near Ross Lough, County Fermanagh, Northern Ireland that had a remarkably modern appearance. The flat, triangular-shaped copper blade was 171 mm (6.75 inches) long, 42.5 mm (1.65 inches) wide, and 2mm (0.078 inches) in maximum thickness, with bevelled edges and a pointed tip, and featured an integral tang that accepted a riveted handle. Analysis of the copper used in the dagger's construction revealed it to be of a type characteristic of the copper that was widely used in Ireland before the introduction of bronze tools and weapons. By around 2000 BC daggers were being cast of bronze, with blades formed by drawing and hammering the metal on bronze anvils set in guides.

The seax of the 5th and 6th century was shorter and narrower than those introduced later on, and could be described as either a large dagger or a short sword. As swords created from pattern-welded iron were enormously expensive weapons at the time, the early seax filled a need for an affordable blade that could be used as both a fighting knife and a utility knife.

With the development of steel and simplified forging techniques, the sword became the preferred bladed weapon for most professional fighting men. During the latter part of the 12th century, the steel-blade dagger

The first fighting daggers to become widely popular in Europe were the rondel dagger and the bollock dagger

. The rondel dagger was a fighting knife with a double-edged, tapered blade and a hilt featuring circular guards. The bollock dagger dates from around 1300-1350, and had a distinctive hilt cap formed from two lobes that acted as a hand-stop. It was especially popular with English and Norwegian combatants.
French and Italian daggers of the 14th century were the first to introduce acutely tapered blades and reinforced points in response to improvements made in armor design and the need for penetration.

Renaissance and Early Modern era

In the Near East, fighting knives such as the pesh-kabz

As the importance of the dagger declined in military service, the weapon became extremely popular in civilian society as an item of daily wear, being used for everything from personal defense to dinner cutlery. In Andalucian Spain

In North America, the advantages of a large fighting knife were seized upon by American frontiersmen, who faced both animal and human opponents of considerable ferocity. This popularity spiked in 1827 with the introduction of Bowie Knife

. After the Bowie knife pattern was standardized during the 1830s and 1840s, it proved to be an enormously popular design, so much so that during the mid-19th century it became synonymous with the term "fighting knife". The Bowie knife largely replaced earlier Native American tools and weapons such as the tomahawk

s on the American frontier, the Bowie knife was often preferred to a single-shot handgun or "horse pistol". During the first years of the 20th century, the classic Bowie knife pattern would be gradually reduced in size and length as its role changed from that of a dedicated fighting knife and weapon to a general purpose knife and tool that could be used as a fighting knife in an emergency.

Early 20th century

By 1900, civilian fighting knives were being mass produced in a countless variety of shapes and sizes, though they all shared the common characteristic of being primarily designed for use in physical combat. However, in military service, the traditional fighting knife began a gradual transition from a "pure" design intended solely for fighting to a knife that could fulfill other roles as well. This trend was not unprecedented, as many nations and cultures had already adopted various multi-purpose fighting knife patterns derived from popular general-purpose knives with cultural and historic roots, beginning with the Anglo Saxon seax of medieval times. Thus Chilean soldiers, for instance, were trained in the use of the Corvo

 were often used as fighting knives by indigenous military or paramilitary forces. Colonial powers that encountered these general-purpose weapons used as fighting knives during a military campaign occasionally adopted them in turn for use by their own military forces, as exemplified by the U.S. Army's Model 1910/17 "Bolo" brush-clearing knife, which would be later pressed into service as a fighting knife in both World Wars.

In World War I, military use of the fighting knife saw the introduction of the "trench knife

On the Allied side, these "knives" were originally little more than sharpened spikes or cut-down bayonets fitted with handles.

The Mark I trench knife was an American trench knife designed by officers of the American Expeditionary Force for use in World War I. It had a 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...

In Western Europe, one dual-purpose fighting knife to be widely adopted by German forces during World War I was the Nahkampfmesser (Close Combat Knife), which despite its name was actually a general-purpose combat and field knife.

World War II

In the Pacific theater of World War II, U.S. Army and Marine Corps personnel frequently employed jungle and utility knives such as machetes, bush knives, hospital corps knives, and bolos

 as fighting knives. These knives were particularly favored by elite or specialist units such as the U.S. Army's Bushmaster

 regiment and Pioneer combat engineer detachment and the Marine Raider and Paramarine battalions of the U.S. Marine Corps. The success of these large knives in individual combat engagements in the Pacific caused authorities to reexamine the suitability of existing "commando"-type fighting knives for troops expected to fight the Japanese soldier in the Pacific.

In late 1942, the U.S. Marine Corps adopted the 1219C2, later designated the USMC Mark 2 Combat Knife or Knife, Fighting Utility, but better known in popular terminology as the KA-BAR
KA-BAR
KA-BAR is the contemporary popular name for the combat knife first adopted by the United States Marine Corps in November 1942 as the 1219C2 Combat Knife , and subsequently adopted by the United States Navy as the U.S. Navy Utility Knife, Mark 2...

. The KA-BAR differed from WWI-era U.S. fighting knives in that it was purposely designed as a dual-purpose weapon, adapted for both combat and as a utility knife. It also differed from some earlier USMC knives such as the Marine Raider Stiletto in that the new knife used a stout, wide blade with clip point that facilitated slashing attacks as well as blade thrusts. Subsequent reports on the effectiveness of the new knife in jungle combat substantiated the Marine Corps decision to standardize the KA-BAR as the USMC's fighting knife for individual Marines.

In contrast, in 1941 Great Britain introduced one of the most famous "pure" fighting knives designed specifically for military use in combat, the British Fairbairn-Sykes fighting knife

Post-WWII to present

Designed for military use, Bo Randall's No. 14 "Attack" Model was a popular fighting knife used after World War II. During Vietnam, Randall received feedback from Captain George Ingraham, a Combat Surgeon in the US Army's 94th Medical Detachment. 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

Tactical knife

A tactical knife is a knife with one or more military (martial) features designed for use in extreme situations. In popular usage the terms "fighting knife" and "tactical knife" are frequently employed interchangeably, despite the fact that a tactical knife is principally designed to be used as a tool, not as a weapon.

Folding knives are rarely if ever designed primarily for use as fighting knives or combat knives. However, many armies and military organizations have issued folding "utility" knives that were not intended to be used as weapons, but which had tactical features that appealed to military personnel as well as civilians.

Critics of the "tactical" folding knife point out that the design is not well suited for individual combat when compared to a purpose-built fixed blade combat knife or fighting knife. The very nature of a folding knife means that it will usually have to be retrieved and its blade deployed during a fight – an impractical maneuver during a fight. Students of knife fighting also point out that any locking mechanism can fail and that a folding knife, regardless of lock strength, can never be as reliable as a fixed-blade combat knife.
