This is a custom made lightsaber machined by the custom saber shop. Green led tri cree, run by a golden harvest V1. The aluminum was chemically weathered. To start the saber remove the lower part of the hilt, twist or pull out the recarge plug, listen for the Alec Guinness “jedi knight” then reinstall the lower section and press the red start button, the upper portion of the graflex switch has green leds, which will flash intermidittently, slower and slower once the saber is turned off. To turn saber completely off reinsert recharge plug and twist until all lights go off.
