Stone Grinder

The Stone Grinder is a production device that can grind items into other resources. It becomes available for purchase at Shop Deed after John moves to the island.

In use, the Stone Grinder accepts specific input items and converts them into different outputs after a processing delay. Some recipes complete in 10 seconds per item, while others take 5 seconds per item when processed in batches. The machine can also handle cases where a single input is returned unchanged, and it can process larger stack sizes such as 16 at once depending on the recipe.

• It is bought from John after his shop is established on the island.
• It is used for material conversion rather than crafting by hand.
• Processing times vary by recipe, so queueing multiple items can be worth it when converting bulk materials.
• Some recipes produce a single output, while others yield multiple results from one input.
