Durability not shown even not after using items for a while

Solution 1:

Using the keyboard shortcut F3 and H will toggle the "Durability" feature on your equipment.

This will show 2 numbers; the items current amount of "uses", and the total uses this piece of equipment has. This will change depending on the item's quality (wood vs diamond), but enchantments will not affect this. Instead, they will randomly lose durability over time.

Items with an Unbreaking enchantment do not always lose durability when used; for a given enchantment level, the chance that they will use durability is 1 in (1+level). The result is that they will last an extra level times their original durability, give or take a few.
