Niman
this style of fighting was originally developed by the Royal Macheteros of the Kashi Mer, although it was later claimed by the Legions of Lettow. Named for two groups of three Kashi gods, Niman was a two-handed fighting style that used one blade for offense, while the other could be used for parrying or for additional attacks. After the Legions of Lettow were defeated by the ancient Jedi Knights, the Jedi adopted both the two-handed fighting technique and its name. Although many Jedi trained in the Niman style to gain basic knowledge of a two-bladed attack, very few ever mastered it completely. Note that Star Wars Insider magazine, issue 68, claims that Niman was the ancient term used to describe the Form VI lightsaber fighting style.
