How to disenchant items with a grindstone in Minecraft
A grindstone strips enchantments from tools, weapons, armor and enchanted books, and gives back part of the experience.

The Grindstone repairs tools and removes enchantments, giving back some experience.
It is made with the Crafting Table from 2 × Oak Planks (or another variant), Stone Slab and 2 × Stick. It is mined with a pickaxe.
Put two damaged items of the same kind in it to merge their durability plus a small bonus, or one enchanted item to strip every enchantment except curses and get some experience back. It is the way to reuse an item with bad enchantments.
Craft it from two sticks, a Stone Slab and two planks. An unemployed villager next to it becomes a weaponsmith.
2 × Stick + Stone Slab + 2 × Any of #planks → Grindstone
// Slots with several items cycle through every accepted option.
