Minecraft wiki entry for Diamonds, associated text: Diamonds can be used to make shovels, pickaxes, axes, and hoes that work almost as fast as gold and last significantly longer than almost any other tool. Most players use their first three diamonds to make a diamond pickaxe, the only tool in the game that can harvest obsidian blocks, except for the extremely late-game netherite pickaxe. Although a diamond hoe lasts longer than any other hoe, with the exception of a netherite hoe, it grants no speed boost and is generally considered a waste of diamonds, as any hoe is sufficient to till farmland. Hoes are more useful in the 1.16 nether update, as they are the quickest tools for breaking leaves, hay bales, sponges, and many other blocks. They can also receive enchantments from the enchanting table, including Efficiency, Unbreaking, Silk Touch, and Fortune. So, the player might want to spend some diamonds on a diamond hoe or purchase one from a toolsmith.
