This is essentially a smaller, pocket-sized version of Mears's Inspirational Guide to Bushcraft.
Not a bad thing, not entirely good either.
When I bought the larger book, I was impressed by the quality and quantity of the pictures and the amount of information contained in it. I was, however, disappointed that the book's sheer size made it impossible to cart around in the wilderness where one to want to practise some of the techniques it describes.
This is the book I wich I had bought instead.
Lots of fairly useless information for most of us - how to skin an elk, that kind of thing. But also some really good stuff - how to build good fires, carve things, build shelter from naturally occurring materials etc.
As far as I am aware, Ray really doesn't have any competition in the mainstream. He is famous for his relatability and excellence in popularising bushcraft. The book reads like he talks, as opposed to being ghost-written and then signed by the star. As such, it is entertaining and inspiring while being educational too.
If you plan on exploring the wilds - take this book with you.
