A knife (plural knives) is a tool with a cutting edge or blade, hand-held or otherwise, with most having a handle. Some types of knives are used as utensils, including knives used at the dining table (e.g., butter knives and steak knives) and knives used in the kitchen (e.g., paring knife, bread knife, cleaver). Many types of knives are used as tools, such as the utility knife carried by soldiers, the pocket knife carried by hikers and the hunting knife used by hunters. Knives are also used as a traditional or religious implement, such as the kirpan. Some types of knives are used as weapons, such as the daggers used by commandos or the switchblades used by 1950s-era criminal gang members. Some types of knives are used as sports equipment (e.g., throwing knives).
Knife-like tools were used at least two-and-a-half million years ago, as evidenced by the Oldowan tools. Originally made of rock, bone, flint, and obsidian, knives have evolved in construction as technology has, with blades being made from bronze, copper, iron, steel, ceramics, and titanium. Many cultures have their unique version of the knife. Due to its role as humankind's first tool, certain cultures have attached spiritual and religious significance to the knife.
Most predark knives follow either a fixed-blade or a folding construction style, with blade patterns and styles as varied as their makers and countries of origin. The word knife possibly descends from an old Norse word knifr for blade.
Shanks and ShivsEdit
These knives are commonly associated with prisoners. Their effectiveness varies depending on the type of material used. For example, a shiv made of glass is more effective than a sharp piece of plastic, but a sharp piece of metal shiv is better than a glass one. These can be made at home.
These knives can fold and are compact. They are undesirable though since they have short reach (even shorter than a fixed blade knife) and will break after lots of abuse.
Belt Buckle KnifeEdit
These should only be used if no other weapons are available, or if the user is taken prisoner by raiders.
The shoe blade was a short blade hidden in a shoe used by worldwide spy agencies (CIA, KGB, ETC.) for killing the enemies secretly.
A combination of a brass knuckle handgrip with a long spike or knife blade on one end, these are among the best weapons to use if you are forced into close-quarter combat. Originally developed for trench warfare in World War I, the brass knuckle can bash a human skull with enough force, and the knife or spike can puncture a metal helmet—to say nothing of a skull—with ease. The trench knife is small, lightweight, and due to its grip, easy to pull out, making it a very effective hand-to-hand weapon. Until recently most of the trench knives that could be found were the poor quality World War 1 models.
In summary, while trench knives are very good for hand-to-hand combat, they can be extremely hard to come by.
