Twin vibro-arbir blades

The twin vibro-arbir blades was a pair of identical blades used by the First Order's Elite Praetorian Guard who served Supreme Leader Snoke aboard his flagship the Supremacy. They were high-tech weapons resistant to lightsaber blows.

Description
Like all the other high-tech weapons used by the Elite Praetorian Guard to defend Supreme Leader Snoke, the tempered metal blades of the separated twin vibro-arbir blades were connected to a compact ultrasonic generator that created a high-frequency vibration across the cutting edge, which increased its lethality in the process.

History
In 34 ABY, the Elite Praetorian Guard carried their twin vibro-arbir blades aboard Snoke's flagship the Supremacy when General Armitage Hux and Kylo Ren of the First Order went to talk with Snoke about their failure. Sometime later, when the Force-sensitive scavenger Rey was taken by Ren to Snoke, the Praetorian Guards used twin vibro-arbir blades along with their other weapons to combat Rey and Ren after the latter killed Snoke. Their bilari electro-chain whips were no match for Rey's and Kylo's lightsabers, resulting in the deaths of all the guards.
