Making hand tools was the most important enabling industry of all in the late 1700s. The father of production engineering, Joseph Bramah, did not start to apply the methods of the wood-worker to metal manufacture until the second half of the 18th century, and it was the availability of tools which could cut cast and wrought iron which made the industrial revolution possible.

Tools made using Benjamin Huntsman's crucible steel process created this capability. The steel industry started in 1740 when Huntsman invented his process. It started with the carburising of Swedish iron in pot kilns similar to those used in all high temperature industries.

The only remaining cementation furnace actually belonged to Daniel Doncaster and Sons. It is located in Doncaster Street in Sheffield, UK, a street named after our eponymous hero, Daniel.
