Extremely rare and expensive blades forged from the mineral cortosis, mined in the closed mines of some planets. Cortosis has the property of deactivating a lightsaber - a strike of a cortosis blade against a lightsaber blade completely discharges the lightsaber and renders it useless for several minutes, giving an advantage over an unarmed Jedi. This is the only distinctive advantage of cortosis blades; otherwise, they remain identical to vibroblades.
