This is a simple mod that adds the Kingdom Key and Kingdom Key D, from Kingdom Hearts.
I made this for myself but thought I'd share it.
They both have custom full-3D models and give you their abilities when equipped.

Kingdom Key:
6 Damage
800 Durability
Enchantable
Ability: Damage Control
Take half damage when under 50% health.

Kingdom Key D:
6 Damage
4000 Durability
Not enchantable
Ability: Second Form
When killing a mob, there's a chance to gain various effect buffs.

Crafting recipe is in images above.

*I may decide to add a few more keyblades later on, but this will not be a mod that contains all of them.
