How do I install Hammerhead?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on Modrinth — not every file is mirrored on our own servers.

What Minecraft version does Hammerhead work with?

The listing gives Minecraft 1.21.5, 1.21.7, 1.21.8, among others. This is the version stated by the author or source site, not something we verified ourselves.

Hammerhead

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Data pack only.

Minecraft 1.21.7–1.21.10Newest
Minecraft 1.21.6
Minecraft 1.21.5
Minecraft 1.21
Minecraft 1.18–1.20.4

⬇ Download for 1.21.7–1.21.10 ⬇ Download for 1.21.6 ⬇ Download for 1.21.5 ⬇ Download for 1.21 ⬇ Download for 1.18–1.20.4

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Hammerhead for 1.21.0

History

Originally this data pack was made by an unknown author, and our local server was a big fan. I updated the mod and added additional blocks in 1.18. Today- finally, we have a 1.21.0 update. Nethrite picks have been added. The original Planet Minecraft page can be found here.

How It Works

If you have 10 levels of experience and place an Iron, Diamond, or Netherite pickaxe, along with an Iron Block on top of an Enchantment table. Your pickaxe will be turned into a Hammer! Hammers can mine a 3x3 area in front of where you're looking.

Shovels (Iron, Diamond, and Netherite) can also be turned into hammers.
