Yeah, my great aunt's bridge partner's husband had a cabinet shop which I used to hang out in after school when I missed the bus --- learned a lot by osmosis just hanging out and helping and doing odd chores.

When he passed away, his wife rented the shop out, to a drug addict who pawned off all the tools he could sneak out in his car.... when there was eventually an auction, not much was left, but I did at least get to buy an (empty) toolbox he had had me assemble from scrap lumber (which I still have on my workbench as a remembrance).

That said, for a flip side look at this sort of thing, consider the case of Charles Babbage trying to get his Analytical Engine made and the dispute over who owned the tooling, him or Joseph Clement, with the latter winning because at the time, a workman owned his tools, even if they were specifically constructed for a customer's project.
