Some of my friends have smiled at the whole idea though most are half converted by my enthusiastic rant about nails; the rest usually at least admit that, if Adam Smith thought they were important, then they are worth a second thought.
If fact, without a vast supply of nails, the industrial transformation of the eighteenth century could not have happened; nails secured the new, architect-designed buildings, the navies, the colonial development - the log cabin and the White House, if you will.
Smith, who was brought up in Kirkcaldy, knew what he was talking about when he saw the nail trade as a paradigm of the benefits of specialisation since one of the main centres of the Scots nail trade was on his doorstep, as readers will see.
I have put this work here in the hope of comments and that someone else will take the study forward - there is lots to do and I would be happy to help with thoughts and references.
