Vibro-arbir blade

The vibro-arbir blade was a melee weapon used by Seventh Guard of Supreme Leader Snoke's Elite Praetorian Guard. It was a handheld vibroblade with a that was resistant to lightsaber strikes.

Description
Like all the weapons used by the Elite Praetorian Guard to defend Supreme Leader Snoke, the high-tech arbir blade was formed from tempered metal blade and was connected to a compact ultrasonic generator that created a high-frequency vibration across the cutting edge, increasing its deadliness. Parallel to edge of the blade was an electro-plasma filament that created an energy blade able to parry a lightsaber. A pair of individual vibro-arbir blades could be joined together at the handle to create a double-bladed staff-like weapon

History
In 34 ABY, the Elite Praetorian Guard's Seventh Guard carried their vibro-arbir blades aboard Snoke's flagship the Supremacy while the First Order was pursuing the Resistance Fleet. Sometime later, when Kylo Ren brough the Force-sensitive scavenger Rey before Snoke, the Seventh Guard used their vibro-arbir blades to battle Rey and Ren after the latter had killed Snoke. Their weapons proved to be no match for Rey's and Kylo's lightsabers, resulting in the deaths of all the guards.
