Lan-dovna was a Vulcan technique of killing another with one's hands, much like Tal-Shaya. Lan-dovna was a method of strangulation using one hand. This martial arts technique was developed during Vulcan's violent past in the time before Surak. After the reforms of Surak, the Lan-dovna technique was still taught to Vulcan adolescents - both males and females. In 2253, two members of the crew of the USS Enterprise were killed by the Human/Vulcan hybrid Daniel Reed while the Enterprise was transporting Vulcan's Glory back to Vulcan.
