Read a great post by Jeff Butler of Northwoods Survival on their Facebook page.

What is interesting and what is essential?  This is a very important questions especially for people who spend a lot of time in the bush.  At NWS we look at it this way:  The ability to make fire by friction = interesting.  The ability to make fire under any weather conditions with a match = essential.  Learning how to flint knap a cutting edge = interesting.  Learning how to use a quality knife = essential.
