[Star Wars] Do lightsabers have friction?

Without friction, a lot of lightsaber combat that I've seen in the Imperial Archives wouldn't be able to take place. 

ex. When two lightsabers clash and are then pushed against each other in that kind of lock where one combatant tries to gain the upper hand, they'd need at least *some* friction to push against each other without sliding off, or the force applied by the combatants against each other would have to be infinitely precise. 

I'm sure that there are more applications where friction would be required, but this is what leaps to mind.

And if what is said about these lightsabers is true and they are made of plasma, it wouldn't really make sense for them to have friction anyhow (if my education on Naboo taught me anything).

Not exactly. Lightsabers are arcs of plasma bound within strong magnetic fields. Those fields interact in ways that generally are "sticky," with very little sliding like a weapon made of a physical material would have.
