One thing I always found lacking in books and information about bushcraft (woodslore, whatever your preferred term might be) was any reasonable discussion of legal issues. Presumably authors hesitate to put forward definitive rules of law in case they are held liable, and doubtless I've missed such information here and there, but the novice will inevitably want to know if their activities are legal.
A prime example is our most essential tool, the knife. You can't wander down the local High Street with a fixed-blade knife in your hand, but I cannot ever recall reading a book where the beginner is told what the laws on carrying and using a knife are. And of course I know that asking the Police will get you an answer, but my point is that a few glaringly important matters such as this are rarely, if ever addressed.
