Vanilla Hammers [Forge]
For 1.19+ have a look at Simply Tools since Vanilla Hammers was merged with Vanilla Excavators to improve some things.
Vanilla Hammers adds a few hammers to Minecraft 1.14+ which can mine a 3x3 area. The hammer is like a pickaxe, so you can mine stone and ore materials.
This mod was originally made by Draylar for Fabric and I ported the mod and took all it's textures to Forge. I hope you enjoy the mod as much as I while making it.
