Origin of 'jackhammer'

The term 'jackhammer' originates from the combination of 'jack,' meaning a device or tool, and 'hammer,' which refers to a tool used to strike or pound. Its etymology can be traced back to the early 20th century, when it was developed to improve the process of breaking concrete and rock. The invention of the jackhammer revolutionized the construction industry, making labor-intensive tasks quicker and more efficient. The early models were primarily operated by compressed air, a feature that highlighted the advancements in engineering and machinery during that era. Over the years, the design of jackhammers has evolved, leading to variations that utilize electricity and hydraulics, broadening their applicability in various construction and demolition projects.
