Please add this mod:

It adds Obsidian and Emerald tools.
It adds 2 new Tiers of tools, namely Emerald and Obsidian, with unique 32x32 Textures. They are both very good tool materials, though their strengths are on different stats.
Due to being very hard, Obsidian Tools are very durable, more than 2x Diamond, and they can be enchanted very well. But they have very bad Weapon properties.
Emerald on the other side makes very good weapons with damage slightly higher than diamond, as well as having better durability.
The basic shape is the same as for all other Tools, but Obsidian requires blaze Rods as Handles instead of wooden sticks.
