ⓘ Hammer

A hammer is a tool for putting nails into objects such as wood. It has a long handle, and a tip with a flat end for hitting nails. The most common type of hammer has a curved end for pulling nails out.

A sledgehammer is a hammer that has a longer shaft, and a more massive head. The user can swing it with two hands and apply more force.

                                     

1. History

Hammers were used around 3.3 million years ago. The first hammers were made without handles. Stones attached to sticks with strips of leather or animal sinew were being used. Hammers with handles were made in 30.000 BCE during the middle of the Paleolithic Stone Age. The hammer was used for building, food and protection.
