When I was in school (in seventies), all boys at least tried to learn how to use and take care of all sharp tools and machines with one up to wood and metal lathe. When I was in school now as a teacher, scissors were the only somewhat sharp things kids were allowed to use. Risk tolerance is so low in our society nowadays, sense of responsibility of children is nonexistent etc.
A semester of machine shop taught me an immense amount, and based on my experience with a lot of techies, 95% more about how the world (and tools) work than 95% of the population.
This 100% should be taught in school, it would have been one of the most useful things I could have learned.
