A grindstone will usually generate at a village weaponsmith shelter.
The grindstone provides an alternative method for repairing Weapons and Tools. When used, it will also remove any Enchantments from items, refunding the player with some Experience Points. The number of experience points depends on the enchantment and the level of the enchantment. If a village contains a grindstone but no weaponsmith, any nearby Villager without a profession has a chance to become a weaponsmith.
