The Bowie Knife is a weapon available off the wall in some zombies maps. It is used as a replacement weapon for your normal knife. It is one knife kill until about Round 9. When you have both the Bowie Knife and Ballistic Knife, you will carry them both in your hands at the same time. This makes you able to have one knife kill up until about Round 12. When Pack-a-Punched, it is one knife kill up until about Round 14.
