Survival Knives
A knife is any cutting edge or blade, hand held or otherwise, with or without a handle. Knives were used at least two-and-a-half million years ago, as evidenced by the Oldowan tools. Originally made of rock, flint, and obsidian; knives have evolved in construction as technology has with blades being made from bronze, copper, iron, steel, ceramics, and titanium.
Most modern-day 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.
Survival knives are knives intended for survival purposes in a wilderness environment, often in an emergency situation when the user has lost most of his/her main equipment. Military units issue some type of survival knife to pilots in the event their plane may be shot down. Survival knives can be used for trapping, skinning, wood cutting and other uses. Hunters, hikers, and outdoor sport enthusiasts use survival knives. Some survival knives are heavy-bladed and thick; others 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.
