The quest for the ideal nail has taken centuries of development. The ancient Egyptians and Romans used organic glue for wood furniture, especially with decorative veneer techniques, but like much advanced technology, glue for wood became a lost art after the collapse of Rome in until the Renaissance, aroundwhen glue and veneer techniques reappeared. During the Middle Ages, furniture was held together with pegs, dovetails, mortise and tenon ts and a few nails.

About in America and in Europe, the modern wire nail was developed. Machinery was invented to cut pieces of steel wire, sharpen a point at one end, and put a flat round head onto the other end.
