Cho mai

In lightsaber combat, a chio mai was the act of cutting off an opponent's weapon hand. This move showed that the Jedi using it had the honor to cause the opponent minimal physical damage; it also showed the skill and mastery of the Jedi performing the move to the opponent.

A notable example was when Darth Vader cut off the sword hand of Luke Skywalker at the end of their duel in Bespin's Cloud City, a favor Luke would return later on.
