Ballistic Knife

The Ballistic Knife is a type of knife that is set to appears in Call of Duty: Black Ops. It is a secondary weapon.

Overview
When drawn, players can fire the knife's blade, which results in a silent one hit kill, much like the Throwing Knife. The blade can be picked up, and loaded back into the handle to be used again. It does not replace the normal melee knife, as shown in the multiplayer teaser, a player is shown knifing (with a different animation) while the Ballistic Knife had no blade in it. Killing a player with the Ballistic Knife's ranged attack gives the player the message "Skewer" at the top of the screen, similar to the Call of Duty: Modern Warfare 2 message "Bullseye!". The Ballistic Knife is one of the few avaliable weapons in the new Sticks and Stones playlist in Black Ops, along with the Crossbow and tomahawk.
