|Source Mod||Thermal Expansion|
A Crescent Hammer is a tool that allows you to modify and break items from the Thermal Expansion mod. The Crescent Hammer does not have durability and therefore cannot break. The Buildcraft Wrench has some of the same properties, but can't be used to break items from Thermal Expansion. To use the Crescent Hammer, simply hold your sneak key (Shift by default) and right-click.
