Lets you build stairs, walls, and slabs out of your favorites ores.
Very simple to use:
-Get the ingot version of whatever you want to make (for example, a diamond)
-Put it in a stonecutter and craft what you want
You can also use crafting tables if you prefer, and it gives the same amount as a stonecutter would (1 ingot = 1 block)
*NOTICE*
For iron walls, you must use a stone cutter (because of the iron bars recipe)
For redstone stairs, walls, and slabs, you use the redstone block.
