Either way, it is perhaps the oldest human tool, perhaps even older than the earliest '' Homo '' Species . By analogy, the name hammer has also been used for many mechanical parts and devices that are designed to deliver blows, e.g. in the Caplock Mechanism of Firearm s.

The head usually has a flat striking surface on one side. The opposite side of the head may have a second striking surface; or a claw or wedge to pull nails, or may be shaped like a ball as in the Ball-peen Hammer . Some upholstery hammers have a magnetized appendage, to pick up Tack s. Popular hand-powered variations include:
