A hammer is a striking tool. Hammers may be used directly, as when striking a nail, shaping metal, or knocking beams apart during demolition, or they may drive another tools, such as chisels or wedges.

Powered hammers also exist, as do electric and pneumatic nail guns.

The face of a hammer head is often specially treated to make it a better striking tool. This may include special hardening or surface treatment to reduce slipping when the hammer strikes. The side of the hammer head, known as the cheek, is not treated in the same way and may break if used as a striking surface.

When driving nails, a nail set may be used between the hammer and nail to prevent the hammer from striking and damaging the work piece.
