Twin revolvers that turn into bladed dusters, I believe. Called Violet Dualis. They look like large knives with brass knuckles for hilts(Dusters), and the ammo storage(not sure what the actual revolving part of any revolver is called) as the crossguard/blade connection. Personally, I think they're pretty cool.
