The Ontario Mark 3 Navy (MKIII) is the standard knife for the US Navy and Navy SEALs.
The Mark 3 was officially adopted by some units in the United States around 1970, and was also sold for general sale. However, due to the obsolescence, it is no longer used because it is no longer able to meet the requirements of the US. It features a 61⁄2" 440 stainless steel blade. It has a saw tooth back and a black oxide finish, with high impact plastic handle and sheath. The original had a steep counter curved point which the Navy requested be reinforced because of damage to the tip of the blade when prying. They have since reinforced the tip eliminating the reverse curve making the point more sturdy. People have found many uses for this knife, including using the butt as a hammer and the blade as a prybar which may cause personal harm. The blade is said to hold a great edge and be very durable.
Apart from the USA, Mark 3 knife is issued to officers of Special Duties Unit and Counter Terrorism Response Unit of the Hong Kong Police Force.
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 Originally made of wood, bone, and stone, over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have been made from copper, bronze,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 polearm or pole weapon is a close combat weapon in which the main fighting part of the weapon is fitted to the end of a long shaft, typically of wood, thereby extending the user's effective range and striking power. Polearms are predominantly melee weapons, with a subclass of spear-like designs fit for both thrusting and throwing. Because many polearms were adapted from agricultural implements or other fairly abundant tools, and contained relatively little metal, they were cheap to make and readily available. When warfare would break out and the belligerents had a poorer class who could not pay for dedicated military weapons, leaders would often appropriate tools as cheap weapons. The cost of training was comparatively minimal, since these conscripted farmers had spent most of their lives using these "weapons" in the fields. This made polearms the favored weapon of peasant levies and peasant rebellions the world over.
The kukri or khukuri is a type of machete originating from the Indian subcontinent, and is traditionally associated with the Nepali-speaking Gurkhas of Nepal. The knife has a distinct recurve in its blade. It serves multiple purposes as a melee weapon and also as a regular cutting tool throughout most of South Asia. The blade has traditionally served the role of a basic utility knife for the Gurkhas. The kukri is the national weapon of Nepal, and consequently is a characteristic weapon of the Nepalese Army.
A cutlass is a short, broad sabre or slashing sword, with a straight or slightly curved blade sharpened on the cutting edge, and a hilt often featuring a solid cupped or basket-shaped guard. It was a common naval weapon during the early Age of Sail.
A blade is the portion of a tool, weapon, or machine with an edge that is designed to puncture, chop, slice or scrape surfaces or materials. Blades are typically made from materials that are harder than those they are to be used on. Historically, humans have made blades from flaking stones such as flint or obsidian, and from various metal such as copper, bronze and iron. Modern blades are often made of steel or ceramic. Blades are one of humanity's oldest tools, and continue to be used for combat, food preparation, and other purposes.
A switchblade (aka switch knife, automatic knife, pushbutton knife, ejector knife, flick knife, flick blade, or spring knife is a type of knife 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 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 dagger-axe is a type of pole weapon that was in use from the Erlitou culture until the Han dynasty in China. It consists of a dagger-shaped blade, mounted by its tang to a perpendicular wooden shaft. The earliest dagger-axe blades were made of stone. Later versions used bronze. Jade versions were also made for ceremonial use. There is a variant type with a divided two-part head, consisting of the usual straight blade and a scythe-like blade.
Seax is an Old English word for "knife". In modern archaeology, the term seax is used specifically for a type of small sword, knife or dagger typical of the Germanic peoples of the Migration Period and the Early Middle Ages, especially the Saxons, whose name derives from the weapon. These vary considerably in size.
Survival knives are knives intended for survival purposes in a wilderness environment, often in an emergency when the user has lost most of his/her 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. 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. Features, such as hollow handles, that could be used as storage space for matches or similar small items, began gaining popularity in the 1980s. Custom or semi-custom makers such as Americans Jimmy Lile, Bo Randall, and Chris Reeve are often credited with inventing those features.
