Kzinti phaser

The Kzinti phaser was a hand-held weapon used by the Kzinti during the 23rd century. It is known to have a stun setting which temporarily knocks its victim to the ground. The weapon was never observed to be lethal.

The crew of the Traitor's Claw used these weapons against Hikaru Sulu, Spock, and Uhura on a planet in the Beta Lyrae system.
