The Chisel is a tool that can be found in Monster Loot or Chest loot as a very rare item. It is used to upgrade machines and can itself be upgraded as well. It also allows the player to open Stardust Crystals obtained from the Stardust Crystal Potion effect.
Each use to carve gems using 5 gems will give the 10 machines of the matching tier a one time-permanent upgrade, regardless of whether all 10 machines have been crafted.
