What is the origin of a ball peen hammer?

The ball peen hammer, also known as a peen hammer, originated in the late 18th century and was designed specifically for metalworking tasks. Its name derives from the rounded end of the hammer, called the "peen," which is used for shaping and compressing metal. This tool became essential in blacksmithing and machinist work, as its dual-ended design allows for both striking and shaping materials. Its unique design reflects the evolving needs of craftsmen during the Industrial Revolution.
