This is the lightsaber of Kyle Katarn as seen in the PC videogame, "Jedi Knight, Dark Forces 2"

This Kyle Katarn lightsaber was constructed by me. I used various items such as a sink tube and polywashers to complete it.
Making your own lightsabers is very rewarding. If you would like to build your own lightsaber, I would recommend purchasing a rotary tool. This tool is very handy and has many uses.
