Chisel

A new tool crafted from a stick and an iron ingot. Using a chisel on a block would remove an eighth of the block. Every use of the chisel would remove a point of durability. This would only work on blocks that have stair and slab variants and would allow the player to create sideways slabs and stairs. When chiseled blocks are broken, they drop a stair or slab depending on how much of the block has been chiseled away. For example, removing 1-3 eights of a block would result in the blocks dropping its stair variant when mined. Removing 4 eights would drop a slab, and 5 or above would drop nothing. This would allow players to create vertical slabs and variants of stairs not obtainable in the game. It would also unlock more building opportunities without replacing the stonecutter, which would still be useful for bulk items.
