I think there should be Sandstone Tools. They would be harder to get because they're only available in one Biome. They wouldn't be godly tools though. It would give players more reason to travel and a better use for sandstone. I am not sure if this idea has already been thought of but This is my idea:

Sandstone Tools would have:

Higher Durability than Stone Tools

Less Mining Speed than Stone Tools

Cannot mine Redstone, Diamond or Gold Ores

Can be combined with Eight Iron to make Reinforced Sandstone Tools which have the Duribility of a Diamond Pickaxe but the same Mining speed as Stone Tools.

What do you think? :)
