Grindstone

A grindstone is a weaponsmith's job site block, used to repair items and tools, or remove enchantments from them.

Breaking
Grindstones can be mined using any pickaxe. If mined without a pickaxe, it drops nothing.

Natural generation
Grindstones naturally generate at village weaponsmiths.

Info


When, a GUI is displayed with two input slots and one output slot.

Placing two items of the same type in the input slots forms a new item of that type with a durability equal to the sum of the durabilities of the two input items, plus 5% of the maximum durability of that item (rounded down), up to the maximum durability for that item type. Both input items are consumed in the process. If either input item is enchanted then this process removes the enchantments and returns an amount of experience based on the number and level of the enchantments. The experience returned for disenchanting makes the grindstone preferable for repairing over using a crafting table, but if the enchantments are desirable then an anvil can be used. Note a grindstone cannot remove a curse on either item (nor can crafting it together with another item in the crafting interface), so items with curses have them until they break or are destroyed. Also, the difference between the anvil and the grindstone is that the anvil repairs the item, uses your experience,  and keeps the enchant/curse. The grindstone still repairs and keeps the curse, but not the enchants, and uses no experience. A single enchanted item (including enchanted books) can also be placed in either input slot, which removes its non-curse enchantments, returning an amount of experience for each, without repairing it or sacrificing another item.

Using a grindstone removes any prior work penalty the item has. However, if the resulting item has curses, the prior work penalty is set to 1 with one curse, or 3 with both curses. Grindstones do not remove items' custom names.

If the action is not applicable (e.g. the two inputs are different items), the arrow displays a red cross, like that of the anvil.

The following tables show the durability bonuses of various items:

Experience
When removing enchantments from items, the player gains experience equal to the minimum modified enchantment level of that enchantment. The final amount is a uniformly-distributed random amount between half the resulting sum (rounded up) and the sum itself.

Changing profession
If a village has a grindstone that has not been claimed by a villager, any villager who did not already pick a job site block has a chance to change their profession into weaponsmith.
