The vibro-voulge was a staff with a blade placed on the top 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.
Like all the other high-tech weapons used by the Elite Praetorian Guard to defend Supreme Leader Snoke, the tempered metal blade of the vibro-voulge was connected to a compact ultrasonic generator that created a high-frequency vibration across the cutting edge, which increased its lethality in the process. Parallel to this, there was an electro-plasma filament that created an energised blade capable of parrying a lightsaber. However, unlike most the of Elite Praetorian Guard's weapons, the vibro-voulge had a power cell in the base of the hilt.
In 34 ABY, the Elite Praetorian Guard carried their vibro-voulges 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 their vibro-voulges along with their other weapons to combat Rey and Ren after the latter had killed Snoke. Their vibro-voulges were no match for Rey's and Kylo's lightsabers, resulting in the deaths of all the guards.
