Its earliest rendition is the MP40's ceremonial dagger, the last upgrade available for the weapon. When used, the default melee of hitting the enemy with the buttstock is replaced by a downwards stab with the knife. It is capable of killing most enemies in one hit, although the higher-level enemies will still take multiple attacks. As an upgrade, it can be used in conjunction with the weapon's other upgrades, including extended magazines, increasing the weapon's overall effectiveness threefold. This dagger is only available via pre-mission upgrades to the weapon and is not found on dead enemies.
