Electro-bisento

The Electro-Bisento was a shaft 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.

Description
Like all the other high-tech weapons used by the Elite Praetorian Guard to defend Supreme Leader Snoke from any menace, the tempered metal blade of the Electro-Bisento 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.

History
In 34 ABY, the Elite Praetorian Guard carried their Electro-Bisentos aboard Supreme Leader Snoke's flagship the Supremacy when General Armitage Hux and warrior Kylo Ren of the First Order went to talk with Snoke about their failure. Sometime later, when Force-sensitive scavenger Rey was taken by Ren to Snoke, the Electro Praetorian Guards used their Electro-Bisentos along their other weapons against Rey and Ken after the latter take out Snoke, but their Electro-Bisentos were no match for Rey's and Kylo's lightsabes, resulting in the deaths of the every Elite Praetorian Guards member.
