Cut nails from 1860
Handmade (wrought) nails, of soft malleable iron with rectangular shanks, drawn by hammer blows to a point were used in house construction from time immemorial until about 1800, when cut nails superseded them.
Numerous patents for nail cutting and heading were issued from 1786 on. The combination machines that cut and headed in one operation were not efficient and in general use until about 1817-1820. Jeremiah Wilkinson of Cumberland, RI., is credited with cutting tacks and later nails from sheet metal from about 1775.
The wrought iron nails were used until about 1850 for "clenching" to stand the jar in facings of window shutters, battens of doors and the overlay of boards (old style) in lathed room partitions. They are not however typical of nails used in general house construction, after 1800.
Cut nails, were cut from iron plates, unlike the wrought nail, which was hammered from "nail rods." Both have rectangular shanks, but the wrought nail tapers on all four sides; the cut nail tapers only on the two opposing sides. The early cut nails were "Headed" by hammering, as were all the wrought nails.
After 1825, with the use of machines that both cut and headed nails, the shank was similar, but the head was stamped level, the top being impressed by a single blow.
