To see if its too far off: I was thinking of a jawa jedi Who combines the 'frozen blaster technology' of a lightsaber/protosaber with the jawa 'ion blaster' to make a saber that deals subdue damage to living targets but reeks havoc on electronics/droids. Such as if he were to stick his saber into a pair of doors, it would be more likely to short out the doors to open rather than melting through the dura-steel.
