> no one ever showed me how to use a single power tool.
This is because using power tools is most of the time following safety protocols and reading the instruction manual. if you learned how to read well, you shouldn't need someone to teach you this (unless you're using highly specialized tools for niche situations, but that's more of vocational training)
What? There's a lot more to learning the intersection of power tools and a given craft area X than just how to not hurt yourself.
Why would I use a spade vs a single point vs a Forstner drill bit? When would I use a backer board? When would I use conventional cutting vs climb cutting? If I want to achieve tolerance X on face F, what should be my sequence of operations? How can I fixture this work to give me the best results? When is a circular saw vs a table saw vs a jig saw vs a mitre saw appropriate?
