Hammer

A hammer is a tool that is used for pounding nails and pegs into wood. A similar tool called a mallet is used for driving pegs and posts into the ground.

Mainstream Smurfs Media
In mainstream Smurfs media, hammers and mallets are used by the Smurfs in their daily routines involving construction. They are occasionally used as weapons whenever Gargamel or something considered dangerous enters the village, and in the comic books are used to pound on Brainy's head when he goes into long boring speeches.
