[How the force works for lightsaber dueling]

The "cuts everything in all directions with no weight" is why a normal person can't use it as a weapon. Without Force reflexes and precognition, you...

 

-- Can tag yourself with it without realizing what you're doing (because it has no mass or inertia, a center of gravity in the hilt and can't be touched on any side ever)

 

-- Can't block blaster shots, which is bad because you have a melee weapon and they dont

 

-- Can't fight actual Force users with lightsabers of their own because they ARE precogs and their blade is at least as fast as yours.

 

Grievous can because he's a purpose-built cyborg that has been trained in saber combat. As a machine he can avoid making mistakes in blade handling and think fast & accurately enough to win a fight with a Jedi.

 

 

As far as canon is concerned, you don't need to be force sensitive to wield a saber. Look at the Clone Wars animated series (which is canon) and check out how many non-force users wield it. To include random people picking up the saber and slinging it around well enough to fight actual Jedi. Its just like any other weapon, with patience and training anyone would be able to wield a saber. It being lightweight and a blade of light only makes it more difficult to use, not impossible for anyone lacking force training.

 

 

As far as the duelist thing is concerned, generally anyone who has trained extensively with a saber will be better than someone who has not. In this case, the knight trains more with it than the consular.

DS Jaesa is crazy and terrified my warrior into marrying her. I felt that he would get dead if a 'no' was given.
