and honestly, as someone who has done stick and weapon fighting, you 1000% accidentally bop yourself in the head from time to time. With blades you tend to be a lot more careful and the way you hold it can make it difficult for those bops to be dangerous, but a lightsaber is basically a sword that’s all blade.
Isn’t this one of the reasons the force is practically required to use a lightsaber? Just so you have perfect control at all times and do not cut yourself in two.
I suppose grievous is an exception, though an argument can be made that him being mostly mechanical allows him to not kill himself.
Do we know if Grievous had force sensitivity at all? Transplanted Jedi blood or horrendous insanity-inducing technology? Or is the robot body just a good enough mix of precise and expendable?
Back when he was Qymaen jai Sheelal, i’m certain I heard of him “carving out his connection” or something of the sort somewhere. So I think maybe a bit of mechanical precision and expendability is what kept him going after severing his connection with the force, which he previously used to train with a saber?
