Ballistic Knife

The ballistic knife is a secondary weapon featured in Call of Duty: Black Ops.

Overview
When drawn, players can fire the knife's blade, which results in an one hit kill, much like the Throwing Knife and Tomahawk. Contrary to popular belief, the ballistic knife does appear on the enemy radar as a red dot when fired. It comes with two knives, but once fired, the knifes can be picked up from where they landed. It is much like Throwing Knife or Tomahawk in the sense that the blades will drop below the aimed point at distance. The blade travels far slower than the Tomahawk, which brings timing and anticipation into account when firing the weapon. It does not replace the normal melee knife, which is still wielded with the left hand during melee attacks. However, it does speed the melee attack up significantly and seems to increase lunging distance. Killing an enemy with the Ballistic Knife's ranged attack gives the player the multiplayer medal "Skewer" at the top of the screen.

Multiplayer
The Ballistic Knife is a secondary weapon in the "Specials" category and is unlocked at level 15. It is one of the few available weapons in the new Sticks and Stones playlist in Black Ops, along with the Crossbow and Tomahawk. The Ballistic Knife is the Tier 20 weapon, the final one used, in Gun Game. However, in Multiplayer, firing the Ballistic Knife causes the player to show up on enemies' minimaps, the same as other guns. Actually firing the weapon produces little to no sound.

Tips

 * The ballistic knife is very effective against dogs to use as a stabbing weapon, as the animation for a stab/slash is faster than a dog's bite.
 * Due to its low starting ammunition count, Scavenger is favored as it will replenish the knives without the player having to pick them up.
 * Lightweight is suggested to make up for missed shots by knifing the enemy.
 * Sleight of Hand is also suggested, so the blades are reloaded quicker.
 * The pro version of Steady Aim allows the player to maximize the increased knifing speed with quicker recovery after a knife lunge.
 * The pro version of Hardened allows the player to make a more precise shot without flinching too much.


 * As the player has to pull the pin before being able to fire the blade, it is advised to switch to the Ballistic Knife after spawning.


 * Although the Ballistic Knife makes almost no sound when firing, it is not optimal for stealth as you still appear as a red dot on the enemy's radar. It is somewhat more effective for stealth in Hardcore modes, but since nearly every other weapon is capable of a one shot kill in Hardcore its effectiveness is limited.
 * In Sticks and Stones, when a player has exhausted or lost all their ammo on the Crossbow, Tomahawk and the Ballistic Knife, keep the Ballistic Knife out for its quick knifing capability. Be aware of "pick-up" icons that appear on-screen since enemy Ballistic Knife ammo can be scavenged.

Zombies
It is available through the Mystery Box. The player is able to pick up knives after being stuck into zombies. The ballistic knife fired to a zombie can be a one-hit kill at any round as long as it is a headshot. Although the ballistic knife has a much higher stabbing strength in zombies (up to about round 5 without the sickle or Bowie knife), it is not a favorable weapon, due to its low ammo count, low rate of fire, and low damage. If the Bowie Knife or Sickle is purchased, it will replace the regular melee knife when wielding the Ballistic Knife.This combination will be effective up until around round 11 and up to the second Hellhound round.

When Pack-a-Punched it becomes "The Krauss Refibrilator" and will revive a player instantly if hit by the blade, which will give the secret trophy/achievement "See Me, Stab Me, Heal Me".

Trivia

 * Ballistic knifes can shoot RC-XDs and destroy them.
 * When knifing an enemy, if close enough the player will stab with both blades.
 * The Ballistic Knife has one of the lowest ammo counts in the Call of Duty series, with only 2 knives to use in a life.
 * Also, the Ballistic Knife has 2 knives still if the player is equipped with the Scavenger perk.
 * Like a grenade, when first pulling the knife out in a life, the player pulls a pin before being able to use it. After pulling out the pin, the switching time is faster than the first switch.
 * If both blades have been fired (i.e. no ammo) and a different weapon is equipped (the primary weapon), when a knife is picked up from the ground or a body the Ballistic Knife will be instantaneously reloaded (no reload animation), but only if it is not equipped when the knife is picked up.
 * If a Bowie Knife or a Sickle is bought before or after upgrading in Nazi Zombies, it will replace the knife in the player's left hand.
 * The player receives the Trophy/Achievement "See Me, Stab Me, Heal Me" when they revive a team-mate with a Pack-A-Punched Ballistic Knife
 * When killing a Zombie by shooting it with a Ballistic Knife, the player will still gain as many points as if they stabbed the zombie.
 * A Ballistic Knife can actually be seen in the Single Player mission Numbers on a shelf next to the rack of the first available weapons cache. However this knife cannot be used and is only decorative.
 * Fired knives will glow yellow if the player can pick them up.
 * It is possible to get a headshot with the Ballistic knife.
 * When both blades are fired a player's character will still seem to have a blade in his left hand. This is the normal knife a character uses to melee.
 * The Ballistic Knife is much like the Tactical Knife attachment in Modern Warfare 2 as melee speed is doubled. However, instead of a handgun and a knife, a player is using 2 knives.
 * If the player fires the Ballistic Knife into an enemy's gun, it will count as a headshot.
 * The Soviet Red Star is visible on the left side of the right knife. It is possibly a reference to its real life manufacturer, the Spetsnaz.
 * There is a small delay from shooting to firing in this weapon.
 * Strangely enough, it can be used to destroy killstreaks, including Helicopters and RC-XDs.
 * The player holds this weapon similar to how Soap holds his knife at the end of Endgame.
 * It's the first melee weapon that can be Pack-A-Punched.
 * Tally marks can be seen on the left hand knife that you melee with via Theater Mode, the tally marks scratched on the knife are most likely just there for cosmetic purposes and not an actual score keeper.
 * The Ballistic Knife is a good weapon to use for accomplishing the "Steel Meets Spine" contract or when trying to achieve a "Backstabber" Medal. This is because the lunge, stab melee of the Ballistic Knife goes straight to the back of the other player rather than the slicing motion of the typical melee which often catches the side of the other player if standing directly behind him.
 * In game-winning killcams, a fired Ballistic Knife will frequently appear to miss the target due to moderate lag commonly associated with killcams.
 * When the player points "The Krauss Refibrillator" at a downed teammate, the cross-hair turns a sky blue color.
 * Interestingly enough, the Ballistic Knife produces recoil that pushes the player slightly backwards, similar to the Wunderwaffe DG-2 or firing an RPG. This can easily be noticed if a player lines up the corner of the screen with an object or building and fires the Ballistic Knife. This is also easily visible while prone. However, the chances of being pushed back having disastrous effects are slim to none.
 * When stabbing an enemy it looks like you are punching them.
 * In zombies, it is the first and currently only weapon that can utilize a blue reticle, which is seen when the knife is pack-a-punched and the reticle is over a downed player, signifying the player can shoot the player and revive him.
 * Even when the knife is out of ammo, a knife can still be seen loaded into the chamber, although it cannot be fired.
 * The "Krauss Refibrilator" is referenced in once of the loading screen notes for Zombies, stating "If red reticles mean enemy and green reticles mean friendly, what do blue reticles mean?"
 * It is odd to note that in ascension, if you have a Krauss Refibrillator with a sickle and shoot a sickle and attempt to pick it up again it tells you may pick up a knife even though you shot a sickle.
 * When you shoot the knife, you can press the reload to instant to go to the reload animation (Xbox 360, Zombies Comfirmed). With the Krauss Refibrillator and speed reload doing this tactic, you can rapidly attempt to revive your fallen comrades.
 * The ballistic knife isnt really that accurate, but when an enemy is slightly to ur left, shoot your ballistic knife curved, and you'll have a direct shot
