If you need to build a fire but all you have with you is your knife, You still can start that fire you need. Making a cord to start a campfire takes little time and it can be done by almost anybody.
The guy in the video creates a friction fire ember using a natural cordage that he makes from tree bark from a nearby brush pile. This is a quick and easy, simple way of making cordage that works great for this type of friction fire. The friction fire method he uses is the traditional method used by the Eskimo people for many generations and is called the “Eskimo strap drill” or “arctic strap drill” fire method.
