Grindstones is a Vintage Story mod by AartHauk. Grindstones adds a craftable frame and grinding wheel for repairing metal tools while reducing their maximum durability.
Why this mod is worth installing
Useful when you want to restore a worn metal tool instead of replacing it, while accepting a permanent loss of some maximum durability.
What Grindstones adds
The mod introduces a grindstone frame and a separate grinding wheel. Assemble the wheel from a metal rod and a suitable quern stone, then place it in the frame to create a workstation for tool repair.
Repairing restores current durability but permanently lowers the item’s maximum durability according to the configured exchange ratio. This makes the grindstone a practical emergency solution rather than a way to preserve equipment indefinitely.
Repair rules can be adjusted for material types and tool categories. Bows, slings, firearms, crossbows, and shields are excluded by default, while a range of metal materials is allowed; whitelist and blacklist options can override the defaults.
