Sai tok

Sai tok was one of the nine marks of lightsaber combat. It was a lightsaber blow which bisected the opponent. The most common sai tok was to cut an opponent in half at the waist, but others applied sai tok by cutting enemies from hip to shoulder or shoulder to hip, or even vertically from skull to groin.

Many Jedi looked down on the use of sai tok against living opponents, considering it Sith-like in its desire to utterly destroy the enemy.
