The format is super handy and therefore the book is always there. The contents are described in a nutshell, that is, in my estimation quite a lot of content fits in this little book. The paper is firm and crisp and keeps hopefully also in outdoor use long without cracking or under wet fingers to dissolve the same times. I do not think I'll get a time in a real survival situation, but the book contains many tips and tricks that will be for me in everyday life or while hiking, or camping useful. For the interested campers and hikers definitely a buy recommendation.
