How to increase attack speed

I am making a mod that introduces lightsabers (Or just swords) into the game, however, I am making certain lightsabers have more attack speed than other lightsabers. However, I dont have any indication of controlling that when making my lightsabers, I just need help on where to control attack speed. If you know, please help me. I would appreciate your help

Also, I am using MCreator 1.9.0
