The Laser ax BL-155 projected four ribbons of monomolecular energy. An energy ribbon refers to an edge that has been energized, applicable to melee weapons that are sufficiently conductive.
An energy ribbon, much like a monomolecular energy cord, significantly enhanced a weapon's cutting capabilities. These ribbons emitted a fluorescent glow and possessed a high voltage, enabling them to tear through metal or disable adversaries with their energy output. Electroripper staffs were equipped with energy ribbons, a notable example being the one wielded by Enfys Nest. The BL-155 Laser ax, utilized by stormtrooper executioners belonging to the First Order, projected four energy ribbons that were monomolecular in nature.
