This is probably the fourth version of Tenel Ka's magical rancor tooth lightsaber I have around the house, hehe. I made two a long time ago with PVC, spraypaint, etc. Then I ordered one from Nocturne Armory. I was up to three! For Dragon*Con 2010 I wanted to have a lightsaber with a bright turquoise/blue blade and a friend told me about ultrasabers.com~! <3
I ordered one of their basic models (with the bright blueish-greenish blade) and took to it with paperclay, blue swarovski gems (she has an orange one in some of the art but the blue blade plus the orange stone made me think of high school and my HS colors, haha XD -- so I stuck with blue) and five different colors of paint.
I had to make it so that I could get to the batteries in the bottom as well, which is why the part of the tooth on the bottom has a ridge. That way I can pull it out when the batteries die and replace them.
(UPDATE! - 1/14/11 - There's a blog post I made detailing the hows and whys and all that jazz concerning the saber. It can be found at this [link]
