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 Originally made of wood, bone, and stone, over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have been made from copper, bronze,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.

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. 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.

According to its description, the Gustloff Company and its chief designer, Carl Barnitzke, got a German patent 766198 in October 1942 for an Armeemesser according to its description. The SG 42 was intended to supplement and later replace the original S84/98 III bayonet of the Karabiner 98k service rifle. The Seitengewehr 42 was designed as a multi-tool combat knife, but could also be mounted as a bayonet on the Karabiner 98k. The S84/98 III bayonet itself was a proven design, but there was a shortage of utility knives in the German military, which were usually procured privately.

The Applegate–Fairbairn fighting knife is a combat knife designed by Colonel Rex Applegate and William E. Fairbairn as a version of the Fairbairn–Sykes fighting knife. The blade has a similar double-edged dagger profile, but is wider and more durable. It features a different handle, made most commonly of Lexan plastic with adjustable lead weights which can change the knife's balance-point. Later models and some custom variants included weights made from pure Teflon, tungsten, stainless steel and aluminum. The blade profile was also changed from a V-grind to a convex, or "appleseed" profile. While this changed the effectiveness of the blade in puncturing, cutting and slicing, it does not lend itself to being sharpened in the field by an inexperienced user. In addition to these modifications, the tang was also strengthened. The current production model made by Böker in Solingen, Germany, uses a fiberglass reinforced delrin handle which solves the issues with earlier models where the handle would crack if exposed to heat.
