Leigh you did a remarkable thing to go out with nothing but a knife and survive for 24 hours.
Ok the resources you found were very limited but full marks for attempting it.
Bushcraft is the ability to use skills to not just survive but survive with some degree of comfort in our natural countryside surroundings.
You addressed this in it’s most basic form being equipped with only a knife, I’m not sure many others would attempt the same challenge.
Having said that it makes sense to carry more equipment, such as a tarp, axe, pots etc. to make the task of surviving in more comfort practicable.
The question is where do you draw the line, between bushcraft and just camping.
I’ve nothing against camping, but using a refined fuel camping stove, chemically enhanced tinder, and instant ignition is not in my opinion bushcraft as no skills are involved.
