A hammer is also a car we drive when out shooting, and sight seeing in the deep Kalahari. 

A hammer is a tool or device used to deliver a sudden blow.

it can be used to signify lots of things, like an act of doing something in huge force.

The are other definitions which people prefer for personal reasons.
