Do Inquisitor lightsabers have 2 Kyber crystals?

Could you please clarify for me if the lightsabers used by Inquisitors in the Star Wars universe indeed possess two Kyber crystals? This detail seems intriguing, and I'm eager to know if it's a distinguishing feature that sets them apart from other lightsaber designs, or if this is a misconception. Your insight would be greatly appreciated.
