Knife

The Knife is the basic and only close-up melee weapon in Call of Duty 4 and one of the melee weapons in Call of Duty: World at War. It isn't commonly used in singleplayer such before COD to COD3, except for missions that include stealth or reconnaissance. This weapon can be triggered by pressing V, or clicking the right stick in the Xbox 360 and clicking the R3 Button on the PS3, as taught in the F.N.G. mission.

Multiplayer
This weapon can be used to trigger a "Humiliation" in multiplayer maps, and is always a one-hit kill no matter what the situation is, providing it hits the target, excluding Old-School Mode multiplayer matches, in which two knife shanks are required. It is well used when a player is nearby an enemy and they are firing. The common way used to kill with the knife in close combat, is to dodge all incoming shots, get behind the enemy quickly and knife them. Another use of the knife in multiplayer can be to take out a sniper standing in a two-story building. When stabbing in multiplayer, the player will "Lunge", similar to Halo. At some rare points the knife will lag out of target and sometimes miss. You can try to knife somebody directly or let them go forward and instantly press knife trigging button and will always kill that player. Experienced players will use the knife when out of ammo, but will run and gun with an automatic weapon more commonly because the knife stabs off target.
