How To Acquire Lightsabers and Lightsaber Crystals:

I think you have to use the KSE Save Editor or cheats in order to acquire these lightsabers and lightsaber crystals. If you have the Steam version you can download KSE from here: https://steamcommunity.com/sharedfiles/filedetails/?id=487038719

If you have the retail version you can download KSE from here: http://deadlystream.com/forum/files/file/503-kotor-savegame-editor/

If you decide to use the in-game cheats you have to enter this:

Double-Bladed Lightsabers:
giveitem g_w_dblsbr211 - Pink Saber
giveitem g_w_dblsbr212 - Maroon Saber
giveitem g_w_dblsbr213 - Aquamarine Saber

Lightsaber Crystals:
giveitem u_l_colo_70 - Crystal Of Life
giveitem u_l_colo_71 - Crystal Of Anger
giveitem  u_l_colo_72 - Crystal Of Confusion

There was no documentation in the readme about if the lightsabers and lightsaber crystals appear naturally in-game. So I think you have to cheat to get them.

Compatibility:

This is compatible with TSLRCM 1.8.5: https://steamcommunity.com/sharedfiles/filedetails/?id=485537937

This mod adds three new double-bladed lightsabers as well as three new lightsaber crystals and is installed with TSL Patcher, so there should be no compatibility issues with TSLRCM 1.8.5.

mjpb3's Darth Nemesis Double Sabers - For KotOR II

I made a request after visiting thelightsaber.com for
three ideas I had for the Darth Nemesis saber. I love the saber
and wanted 3 double bladed sabers based off of the Nemesis
saber.

My request was graciously made for me by T7nowhere:
http://www.lucasforums.com/showthread.php?t=159596

After making my sabers, T7 gave me permission to make this
mod, placing the sabers in game and releasing them.

T7, I hope I have done them justice, because these sabers
ROCK! Thanks for letting me play with them.
