Chisel 2 is an AWESOME mod - it's perfect for doing what I like to do best in minecraft, and what I find most addictive - building!

 

With only 1 item, you can gain access to more than 100+ blocks!
What is that item called? The Chisel.

 

In the creative menu, if you type in Chisel, you won't get the specific item I'm talking about.

Rather type in Iron Chisel, Diamond Chisel or obsidian Chisel, and take the first result.

In survival mode, these are quite cheap and easy to craft. Each Chisel Upgrade level does not give you access to more blocks, but grants you more durability to waste!

To use a Chisel, simply left click on a block that can be chiseled, or right click and put a block in the GUI!

 

To craft a Chisel, all you need is a stick and 1 iron ingot / 1 diamond / 1 obsidian.
