A '''grindstone''' is a [[block]] that repairs [[item]]s and [[tool]]s as well as removing [[enchantment]]s from them, except for [[Curse|curses]]. It also serves as a [[weaponsmith]]'s [[job site block]].

== Obtaining ==

=== Breaking ===

Grindstones can be obtained using any [[pickaxe]]. If mined without a pickaxe, it drops nothing.

=== Natural generation ===

Grindstones naturally generate at [[village]] [[Trading#Weaponsmith|weaponsmiths]].

=== Crafting ===

== Usage ==

A grindstone can be oriented in different directions. In [[Java Edition]] it doesn't need a supporting block. In [[Bedrock Edition]] it breaks if unsupported.

=== Repairing and disenchanting ===
[[File:Grindstone GUI.png|thumb|right|176px|Interface for the grindstone]]

When {{control|used}}, an interface is displayed with two input slots and one output slot.

Placing one [[Enchanting|enchanted]] [[item]] in an input slot forms a new ''non-enchanted'' item of the same type and durability in the output slot. Removing the item from the output slot consumes the input item and drops some [[experience]].

Placing two [[item]]s (enchanted or not) of the same type in the input slots forms a new non-enchanted item of that type and 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 its maximum durability. Both input items are consumed in the process. If either input item was enchanted, then removing the output item drops some [[experience]].

The amount of experience dropped depends on the number of enchantments and levels of each, but it is partially random. For example, [[Fire Protection]] I gives 5-9 experience.{{info needed|Is it an even distribution or a triangular distribution?}}

As with all non-enchanted items, the new item has no [[Anvil mechanics#Anvil uses|prior work penalty]]. A grindstone cannot remove a [[curse]]. Grindstones also do not remove an item's custom name.

If the action is not applicable (e.g. only one non-enchanted item, or the two inputs are different items), the arrow displays a red cross like that of an [[anvil]] and no item appears in the output slot.

The following tables show the durability bonuses of various items:

=== 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 [[Trading#Weaponsmith|weaponsmith]].

=== Experience ===
When removing enchantments from items, the player gains experience equal to the minimum [[Enchanting/Levels|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.

=== Piston interactivity ===
Grindstones cannot be pushed by [[piston]]s or pulled by [[sticky piston]]s.

== Trivia ==
* Before the grindstone was added, a different method to remove enchantments was floated for [[Update Aquatic]], which would have been by means of feeding items to a mob known as "[[MINECON Earth 2017#Mob C|the Great Hunger]]", but the mob lost the [[MINECON Earth 2017]] mob vote to the [[phantom]].
