The Diamond Hoe is used to till dirt and begin the process of farming. Although it has the highest durability of any Vanilla hoe, it is rarely used because of its cost (requiring 2 diamonds to make). It is also used in the creation of the Farming Turtle.
The Diamond Hoe has a durability of 1,562 uses. It can be enchanted with an Enchanting Table. The only enchantment available is Unbreaking, which can increase the tool's durability by 2-4 times, depending on the level of the enchantment.
