Tollan hand laser
Curved, triangular-shaped weapon, steel gray in color, used by Tollan security guards. When fired the weapon produces a thin line of violet energy (possibly plasma, though the energy form remains unknown), taking down assailants with precision and efficiency.
The hand laser may have both stun and kill settings, though this has not been demonstrated.
