Hammers Extension is a vanilla-friendly forge mod, adding hammer tools to your game and letting you mine 3x3x1 blocks (the same block types as pickaxe)
Besides normal hammers, there are also Enhanced Hammers. The two most important aspects of normals hammers is their durability, which is 10% better than pickaxes', regardless of each ore, and their efficiency, which is a bit worse (slower), compared to pickaxes.
Whereas Enhanced Hammers' durability is 30% better than pickaxes' and also the efficiency is a bit higher (faster)! What's the catch with them? They are harder to craft, naturally, for example, you're gonna need an Enhanced Stick instead of a regular one. You'll find all the craftings below, however, I recommend JEI for that.
