Forum:KB:Dual Phase Lightsaber

My friend and I were having a discussion on dual-phase lightsabers. I said that dual phase sabers used two different crystals that were switched when the phase is changed. I got this from Corran Horn in the Dark Tide Duology, where he, on multiple occasions, switches his blade from silver to (I believe) purple. Am I correct in this, or did I just make this up somewhere along the line? Thanks. - DarthDragon164 Dragon's Lair 20:47, 8 December 2008 (UTC)
