You know, honestly, I seriously doubt Sammy L. Jackson really cared about the history of the lightsaber when he asked Lucas for a purple lightsaber. All you have to do is sit back and merely say... "It is Samuel L. Jackson".
I wouldn't be surprised if the bottom of his lightsaber had 'B.A.M.F.' on it.
If you know Sammy Jackson, then you know what B.A.M.F. stands for.
Classic Lucas Games lover.
