A Jedi tool and a Sith weapon? And why do you need such a thing? There is much weight - much craving - attached to such a tiny thing of light. A lightsaber - any weapon - only achieves worth in how it is wielded; in the effort, in the struggle, of one who holds it. Such a weapon does not make a Jedi or a Sith, and at times, it makes them much, much less than they are.
