Mass Producing Mandalorian Iron

Depends on what you consider "mass" to comprise. Lightwips are a goofy idea in most respects (although the inconsistent FX in ANH have lead to some theories about lightsabers having metal rods in them, so you could argue a canon basis for that I suppose.) The idea of "particle/plasma" based lightsabers (Which due to inconsistent authorship extends back some time into the EU the same way it does fro blasters) can technically be considered a "mass" weapon.

You forgot that the lightsaber is differentiated from Luke green saber.
