Photon-knuckles are a type of Hardlight generating weapon developed by the Vaul for close quarters combat.

The knuckles appear as a curved, triangular-shaped weapons while inactive (Stargate SG-1: Tollan sidearm). Once activated, they project a solid hexagonal barrier of photons (Ratchet & Clank - Secret Agent Clank: Holo-Knuckles; DC Comics: Power Ring; Mass Effect: Kinetic Barrier).

When used offensively, the knuckles can increase the force of impacts by 400%. Even unarmored Terrans can used the knuckles to knockout or even kill a rampaging Ultralisk with proper training.

In defensive roles, Photon-knuckles impervious to small and large caliber rounds alike. Nothing short of a kamikaze fighter can shatter the hexagonal barrier. Even after being overloaded, the knuckles can re-establish the field within seconds as long as there is energy in its power cell.
