The Military Knife is a melee weapon used by Sam Stone. The knife, along with the Schofield .45, are the first weapons the player spawns with when they start a new game.


  • The military knife is a single-bladed knife, used for close-combat, though it is still considered one of the most powerful weapons of the respective games.
  • The knife has a different model in Serious Sam: Xbox.
  • In Test 1, the knife could be swung at a faster rate, though it dealt less damage.
  • Enemies with 120 or less health can be instantly killed, without alerting the whole group or horde of the player's presence.

NETRICSA descriptionEdit

  • Weapon: Military Knife
  • Weight: 1 1/2 lbs
  • Length: 11"


An ordinary single-blade military knife. Used as a tool or silent weapon.


  • Use for silent slaying of smaller enemies from behind.


  • Despite seeming like the most underwhelming weapon in Sam's arsenal, the military knife should never be underestimated. Not only does the weapon have a slightly longer range than one would expect, but the 120 damage it deals per slash is devastating to all but the largest of enemies.
  • The knife should be used only to silently kill smaller enemies or wound bigger ones. For example, the Sirian Werebull requires only three slices, which means one could preserve ammo by using the knife.
  • The knife should never be used for stronger enemies, such as Major Bio-mechanoids or ranged opponents.
  • The knife is heavily effective against both types of Gnaars and Scythian Witch-Harpies, with the capability of killing them with one swipe. Against Kleers, two slices will do. The knife does more damage per minute than both shotguns, so it's a good alternative when the fighting arena is spacious for evading enemy attacks.
  • If combined with Serious Damage from The Second Encounter, this is a very devastating weapon that can almost kill medium-powered targets.

Kill 50 Sirian Werebulls with the knife.


  • The knife is very similar in appearance to the OKC-3S bayonet and KA-BAR knife.
  • Though NETRISCA states that you can use the knife for stealth attacks on enemies from behind, this isn't usually possible most of the time, as enemies are alerted to the player's presence even if they are behind the enemy.
