That looks very archaic, thank you🙏🏻. Maybe Aston Martin uses them for making their cars🤔? They are all hand built, in The UK.
Certainly takes a highly skilled craftsman. There are probably CNC machines that do this in a much more controlled way for today’s hand-craft deficient industrial designers 😅
