: The first patent for the modern hammer—featuring a metal head and a hardwood handle—was granted to Theodore H. Gilman in 1875. The Mechanics of Impact

: Modern high-end hammers often use titanium. Titanium heads are lighter but transfer energy more efficiently with less recoil and vibration, which reduces user fatigue and repetitive strain injuries compared to traditional steel. At its core, it is a force amplifier
