Stonecutter

A stonecutter is a crafting block which, when opened, allows for the crafting of stone and stone-related items, such as block of quartz, sandstone, stone bricks, stairs, slabs, and bricks. The stone cutter was created to remove blocks from the crafting table menu and the inventory crafting menu. It will most likely be removed once the MATTIS system is discontinued, however it will probably stay for a while because of the speed MATTIS provides.

Crafting
The stonecutter is crafted with four cobblestone. However, a crafting table is still needed to re-obtain it as it is necessary to craft a pickaxe to mine stone. (Unless you use strategic creeper/TNT explosion, although this is very impractical, as it might all together destroy the block)

Trivia

 * The texture for the stonecutter appears to use the furnace texture as a base, with a few additions. It has a saw blade on it too.
 * The crafting table (in Pocket Edition) is not able to make stairs and the type anymore because of the stonecutter.
