Chimersword
From Warhammer 40k - Lexicanum
The Chimersword is a sword used by members of House Chimaeros of Adrastapol as a ceremonial and dueling weapon. With an appropriate twist of the wielder's wrist, the weapon can disassemble into a segmented sword-whip made of metal cord and sharpened discs. They are used in a similar manner to the Minotane Hammers of House Minotos, the Pegassine Rapiers of House Pegasson, and the Draconblades of House Draconis.[1]
