Bushcraft has become just another hobby. Not just about survival. People spend lots of money on there hobbies, doing and buying things they don't really need, but want. Nothing wrong with that, if that what you like. You only life once, right?

As for buying a bowdrill, maybe it's the lazy man approach to learn new things. I'm not sure, I just gathered wood in the forest and learned how to bowdrill myself... Learning to find the right wood, is just as important as using the drill it self.
