Blake's weapon, Gambol Shroud, is described as a "variant ballistic chain-scythe". While it seems to resemble an oversized cleaver, that's actually its sheath, which has a sharp edge in itself. The weapon itself is a katana with a gun attached to it, and the gun's trigger is itself attached to a ribbon Blake wraps around her wrist.
