The hammer is used to destroy stones on the player's farm. Large stones will require six strikes to destroy; small ones require only one strike. A hammer can also flatten out tilled soil. It upgrades every 100 uses, for a maximum of two times.
A gold hammer (third and final upgrade) is necessary to smash the rock on the Kappa's Pond (next to the fisherman's tent) to retrieve a Power Berry.
