This is incorrect. The Wookiepidia page is incomplete. Rise of the Separatist states it has an "ultra-low-output power generator and either a kathracite or danite crystal. They produce a massless blade like that of a full-power lightsaber, but it causes, no lasting damage to opponents. This hardwired, low-powered setting allows Initiates to practice their lightsaber forms, without the risk of dismembering their instructors, sparring partners, or selves." -Training Saber pg. 55
It is possible that power level, not the crystal may be the deciding factor.
