That depends on what it is you're trying to use. Blades are fine, any blade with a 1" diameter works. The LED modules would require soldering and tinkering with the electronics. The claws would need some place to be mounted on your saber, which would require machining slots and drilling holes for screws. Couplers and spear extensions will only work with SaberForge sabers as they use their own threading size that is different from the MHS system.
