A common pickaxe can be repaired with an anvil and an iron ingot. Right-click the open iron felt on the ground, put the iron pick in the first grid, put the iron ingot in the second grid, and take out the repaired iron pick from the third grid (a little experience is needed, and the durability recovery is not added), or both of them can be repaired with the old iron pick in the composite column (no experience is needed, the iron felt can be repaired at any time, and the durability can be increased, for example, only 65,438 is left for the two durability. Note: but if it is an enchantment tool, don't use this method, it will make the enchantment attribute disappear and become an ordinary pickaxe!
