If you think you're gonna make the ultimate anti-force weapon,it won't happen. Many have already stated it. You need to play smart, not have the most effective weapon.
I'll provide an example(s):
1. Let's say your anti force weapon is on you while you're fighting a jedi. Your main goal is to not get cut by the plasma blade. Little do you know, the Jedi is picking up a boulder with the force and he plans to drop it on you. You have basically lost to telekinesis, not the blade.
2. You're fighting a sith lord. You come to swing at him with your sword but he blocks it with his lightsaber. You go for another swing and you miss, he has a chance to force shock or choke you or even swing his blade at you. You lose again, end of story.
Many FU concepts need to be taken into consideration other than just a sword that's resistant to a lightsaber. Like I said, others said it before me but just was expanding with a scenario. I wish you good luck but this'll be a long ride... trust me.
