I think it’s also about toxic plants to avoid. Testing is already done (thousands of people died for you, it’s called empirical knowledge) why not just take that with us!? Tools can be built easily with a good survival book. I would not spend a unique choice on an axe.
You will not survive not even 3 days with that book. You will put all your faith in that book and your mind will not be able to distinguish between the true plants and the ones from the book, because you are too hungry, reading and wasting time. Also keep in mind that books are referring to specific regions and maybe you are in a different region where those plants do not grow.
