One of these multipurpose designs was the sawback bayonet, which incorporated saw teeth on the back spine of the bayonet blade.

It was initially adopted by the German states in 1865, ( from which point onwards till the middle of WWI approximately 5 % of every bayonet style was issued with a sawback version ) Great Britain in 1869, Belgium in 1868 and Switzerland in 1878, ( who introduced their last model in 1914 ).

THe original sawback bayonets were typically all heavy sword type bayonets, issued to engineers, with to some extent the bayonet aspect being secondary to the " tool " aspect, later German sawbacks were more of a rank indicator than a functional saw.

The sawback proved relatively ineffective as a cutting tool, and was soon outmoded by improvements in military logistics and transportion ; most nations dropped the sawback bayonet feature by the turn of the century.

The German army discontinued use of the sawback bayonet in 1917 after protests that the saw-toothed blade caused unnecessarily severe wounds when used as a fixed bayonet.

Current bayonets have gone back to the sawback ; the Russian / Eastern Block AKM's started the trend, and the US M9 and OKC3C and the British L3A1 followed, all on small knife bladed weapons and often with built in wire cutter adaptations.

During the 2006 riots in Bangkok, Red-Shirt protestors carried " Sapatda ," which resemble an over-sized bowie knife with sawback cuts in the spine.

The pre-existing structure left over from mountain-building has strongly guided glacial erosion: mountains in Banff include complex, irregular, anticlinal, synclinal, castellate, dogtooth, and sawback mountains and many of the mountain ranges trend North-Northeast, with sedimentary layering dipping down to the West at 40-60 degrees.

The tools carried by the pioneers included a sawback sword, pickaxe, billhooks, shovels, and axes.

As Mitchell was about to graduate from the Washington Seminary in 1918, she met and fell in love with another Harvard student, a young army lieutenant, Clifford West Henry, who was chief bayonet instructor at Camp Gordon from May 10 until the time he set sail for France on July 17.

Until the early 20th century rifles tended to be very long ; an 1890 Martini-Henry was almost 2 m ( 6 ft ) in length with a fixed bayonet.

The bayonet / musket combination was, however, considerably heavier than a polearm of the same length.

The danger incurred by the use of this bayonet ( which put a stop to all fire ) was felt so early that the younger Puységur invented a socket bayonet in 1678 that fitted over the muzzle using a circular band of metal, allowing the musket to be loaded and fired.

The decision to redesign the ( dismounted ) bayonet into a multi-purpose tool was viewed by some as an acknowledgement of the decline in importance of the fixed bayonet as a weapon in the face of new advances in firearms technology.

The trowel bayonet or spade bayonet was another multipurpose design, intended for use both as an offensive weapon as well as a digging tool for excavating entrenchments.

Rice was given leave in 1877 to demonstrate his trowel bayonet to several nations in Europe.

A bayonet designed by Lord Elcho was intended for chopping and other sundry non-combat duties, and featured a double row of teeth so it could be used as a saw ; it was not produced in great numbers and was not standard issue.

However, many units retained cuirasses and helmets for their protective value against sword and bayonet strikes and the morale boost these provide to the wearers.

One of the earliest weapons fashioned by human beings and their ancestors, the spear is still used for hunting and fishing, and its influences still may be seen in current military gear such as the rifle-mounted bayonet.

After Mick Dumke, a reporter for the Chicago Reader, questioned the effectiveness of the city's handgun ban, Daley picked up a rifle with a bayonet from a table of confiscated weapons and told him, " If I put this up your butt, you'll find out how effective it is.

In the United States Navy before the American Civil War, bayonet blades were even affixed to single-shot pistols, although they soon proved useless for anything but cooking.

Cutlasses remained the favoured weapon for the navies of the time, though Queen Victoria's Royal Navy gave up the pikes once used to repel attacks by boarders in favor of the cutlass bayonet.

Besides its utility as both a fixed bayonet and a digging implement, the Rice trowel bayonet could be used to plaster log huts and stone chimneys for winter quarters ; sharpened on one edge, it could cut tent poles and pins.

)- long quadrangular épée spike for the bayonet of the Lebel Model 1886 rifle, the Épée-Baïonnette Modèle 1886, resulting in a rifle and bayonet with an overall length of six feet ( 1. 83 m ).

German ordnance authorities responded by introducing a long sword bayonet for the Model 1898 Mauser rifle, which had a 29-inch barrel.

With an overall length of 5 feet 9 inches ( 1. 75 m ), the German Army's rifle / bayonet combination was second only to the French Lebel for overall bayonet ' reach '.

In 1905 the German Army adopted a shortened ( 370mm or 14. 6-inch ) bayonet, the Seitengewehr 98 / 06 for engineer and pioneer troops, and in 1908, a short rifle as well, the Karabiner Model 1898AZ, which was produced in limited quantities for the cavalry, artillery, and other specialist troops.

In response to criticism over the reduced reach of the SMLE rifle and bayonet, British ordnance authorities introduced the P1907 bayonet in 1908, which had an elongated blade of some seventeen inches to compensate for the reduced overall length of the SMLE rifle.

The conflict is often compared to World War I, in that the tactics used closely mirrored those of that conflict, including large scale trench warfare, manned machine-gun posts, bayonet charges, use of barbed wire across trenches, human wave attacks across no-man's land, and extensive use of chemical weapons such as mustard gas by the Iraqi government against Iranian troops and civilians as well as Iraqi Kurds.

The conflict has been compared to World War I in terms of the tactics used, including large scale trench warfare with barbed wire stretched across trenches, manned machine-gun posts, bayonet charges, human wave attacks across a no-man's land, and extensive use of chemical weapons such as mustard gas by the Iraqi government against Iranian troops, civilians, and Iraqi Kurds.

The rifle-mounted bayonet, which has its origin in the spear, has seen use by the United States Army, the United States Marine Corps, and the British Army as recently as the Iraq War.

Prior to World War I, bayonet doctrine was largely centered around the concept of ' reach '; that is, a soldier's theoretical ability, by use of an extremely long rifle and fixed bayonet, to bayonet an enemy soldier without having to approach within reach of his opponent's blade.

Soldiers soon began employing the bayonet as a knife as well as an attachment for the rifle, and bayonets were oftened shortened officially or unofficially to make them more versatile and easier to use as tools, or to manuever in close quarters.

Given Russia's often inadequately trained conscript armies and the use of inaccurate smooth-bore muskets, Russian officers preferred to use the bayonet charge in lieu of musket volley fire where possible.

Modern warfare, however, does still see the use of the bayonet for close-quarter fighting.

The bayonet of the Soviet AVS-36 could be attached to the barrel vertically for use as a monopod

Aside from its use in massed charges, the bayonet remains useful as a substitute utility knife, and some authorities continue to insist that the bayonet serves as a useful training aid in building a soldier's morale.

Training in the use of the bayonet has been given precedence long after the combat role of the bayonet declined as it is thought to increase desired aggressiveness in troops.

Twin BNC ( also known as twinax ) connectors use the same bayonet latching shell as an ordinary BNC connector but contain two independent contact points ( one male and one female ), allowing the connection of a 78 ohm or 95 ohm shielded differential pair such as RG-108A.
