Grindstone
A workstation for repairing tools and crafting new ones.
Notes
The Grindstone is a mid-game workstation for repairing and crafting iron tools, including axes, hammers, and pickaxes. It requires a Tier 2 enclosed room with at least 18 m³ of free volume, so plan your workshop with brick or equivalent materials to meet that tier. Installing a Blacksmith Upgrade module will reduce resource costs and craft times, making tool production and maintenance more efficient.
