The Steel Hammer, added by the Nether Expansion idea pack, is crafted with 5 Steel Ingots and 2 Sticks. It functions as both a weapon and a tool. A hammer can only be crafted from Steel Ingots; it cannot be made from any other material, similarly to the Battleaxe. However, there is a version of the Hammer called the Holy Hammer and another called the Unholy Hammer.
As a weapon, it does the same damage as a Steel Axe (5 HP). However, unlike the axe, it does not take double durability damage.
As a tool, it can be used to right-click on Anvils (use them) so that they break half as fast. This is a unique property.
