create an item that has its own xp

I wanted to make a mod that would allow me to have an item that, by gaining XP, I could use its skill, and also that same item would be compatible with other skills, but I don't know how (for example, I have a sword that has cutting power and a power to rotate, however, to be able to use it, you need so much of the sword's own xp instead of the normal xp)
