Lightsaber combat/Legends

"Aggressive, a Jedi should be not...unless fighting with his lightsaber, he is. The aggressive, the duel favors. Strike a balance, you must, between aggression in your arms peace in your heart. When find it you, unstoppable you will become."

- Yoda

History
All Jedi were taught the basics of sword fighting, including the thrust and how to defend against it, although thrusts were rarely used in lightsaber combat and no Form used them.

Early in the history of the Jedi Order, Padawans were injured or killed in unsupervised lightsaber training duels, requiring the implementation of security systems and limiting access to Jedi Temple sparring rooms to Knights and Masters only. Safety systems included sensors to detect when a lightsaber blade was too close to a living being, and energy dampeners to deactivate the blade if so. However, most Jedi switched the safeties off as an exercise in control, and to build their student's faith in the Force.

Seven Forms of the Jedi Order
Master Talyn preferred the genteel forms like Form II, of which Dooku was a master. Talyn never reached Dooku's level of mastery with the form.

Other forms and styles
Focusing on battle and dissatisfied with the basic lightsaber instruction given by Master Talyn, the Padawan Selon developed a unique lightsaber form that blended Form IV and Form VI to create an aggressive and powerful style.
