Shiak

Shiak was one of the nine marks of contact in lightsaber combat and described a stabbing attack with the point of a lightsaber. It was generally accomplished with a single-handed lunge, although a two-handed jab or lunge was also called shiak. Shiak was the preferred mark of contact of Makashi stylists, and the preferred method of delivering a killing blow for Jedi Knights, as it left the body more intact than other killing blows.
