History of ironing and irons

Flat irons were also called sad irons or smoothing irons. Metal handles had to be gripped in a pad or thick rag. Some irons had cool wooden handles and in 1870 a detachable handle was patented in the US. This stayed cool while the metal bases were heated and the idea was widely imitated.
