If you are entering commands in Minecraft to perform actions, ‘/enchant @p binding_curse 1’ is the input you need to type. That is how you enchant items with The Curse of Binding in Minecraft.

Players should enchant their armor, weapons, and tools in Minecraft to make them better, stronger, last longer, deal more damage, and more.

Minecraft tools differ from other enchantable item types in that you're going to be using mostly the same enchantments on an optimal build.
