The Knife is the weapon of choice for those who like to sneak up on their enemies. Though ineffective in face-to-face battles, it can silently dispatch an enemy who is not alerted by the wielder's presence.
The Knife should be used when there is a single human enemy in the area that is not in alert mode, as it can kill the enemy in one hit if its back is turned. It can also be used to conserve ammo in Fear Effect if crouched while hitting the attack button, as often times enemies will misfire.
