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 they 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.
