Combat Knife

Use
The Combat Knife is the default knife you get on every CoD game mode for all CoD games. On zombies it does 100 damage to the undead. The combat knife can be traded for the Bowie Knife for $3000. Aslo other melee weapons are supplied but this is the default so it will always be there. On Campian and Multi-Player one stab is a kill, unless double health is on. You can never buy this knife or pick it up once its replaced.
