Ballistic Knife

The Ballistic Knife is a type of knife that appears in Call of Duty: Black Ops. It is placed in the player's inventory, and can be drawn like Claymores and C4 in Call of Duty 4: Modern Warfare and Bouncing Betties in Call of Duty: World at War. When drawn, players can fire the knife's blade, which kills in one hit, 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 "Bullseye!".

Trivia

 * This weapons seems to be easier to handle since the player can equip it instead of holding a button down.
 * The Ballistic Knife's extra blade can be seen in the left hand, and can be used as a regular melee attack. The blades appear to be akimbo, so left trigger must normally melee, and right trigger would fire the knife in a straight beeline.
 * There is a red star on the right knife, it may be a Soviet Star considering ballistic knives were highly used by the Soviets.
 * The Soviet Star might be an add-on from Create-a-Class 2.0.
 * The Ballistic Knife is one of the main weapons used by the Spetsnaz.
 * You can use the Ballistic Knife to kill someone stealthier and a fast manner than using a gun.
