Curse of Binding
|This feature is exclusive to Java Edition and Legacy Console Edition.|
Curse of Binding is an enchantment that prevents removal of the cursed item from its armor slot.
An item with the Curse of Binding cannot be removed from any armor slot unless the player is in Creative mode, the player dies, or the item breaks. For items without durability, the player must die to remove the item, making it permanently unable to be removed once equipped in Hardcore mode.

true, the player keeps the cursed item even after death. Only breaking the item removes it.
A player cannot remove the enchantment using a grindstone; instead, the item returns to the player still cursed.
