Tactical Knife

{{game|mw2}

The  is a weapon attachment in Call of Duty: Modern Warfare 2 for handguns. It allows the character to hold both a pistol and a knife at the same time, letting the player stab about twice as fast. The Tactical Knife can be used with all handguns, although in the single player campaign it is only used with the USP.45. The knife is held using the Harries technique, which is mainly used to hold a flashlight. When using Akimbo USP .45s, the knifing speed is actually faster than a tactical knife and the range of the knife attack lost by using the tactical knife isn't lost with the akimbo USP .45's which actually makes them more reliable for knifing than a tactical knife.

The ability to knife faster and more frequently is advantageous in close quarters combat. Players will often combine the Tactical Knife with Marathon, Lightweight or Cold-Blooded, and Commando or Ninja perks to create a fast, specialized melee class. This is often looked down at by other players. A common full class of this system uses a USP .45 or .44 Magnum with the tactical knife. The equipment will usually be a throwing knife or semtex, and flash or stun grenades.

Some innovative Riot Shield users might equip this on their secondaries, so they can quickly knife the enemies who try to knife them. As well as counter other Riot Shield users, since flanking their side is easier with the Tactical Knife than it is with a Shield. The logic behind having a Tactical Knife and a Riot Shield is simply for better melee versatility, considering the Riot Shield is a two-hit kill unlike the Tactical Knife. However, this setup may prove rather useless in Hardcore game modes because of the reduced health system, the Riot Shield would be an instant kill anyway.

Trivia

 * In early demonstration videos, such as the Cliffhanger video, the knife user slashed with it. In the final version, the user stabs with the knife. This is likely because stabbing is a quicker motion than slashing and produces more lethal results.
 * In singleplayer, the USP .45 always appears with a Tactical Knife, although never identified as such.
 * In multiplayer, if the player looks at someone using the Tactical Knife, it would appear as if the user had no Tactical Knife at all, just holding the pistol with two hands. Also, Tactical Knife uses same player model melee animation as generic melee.
 * The .44 Magnum has a different reload when equipped with the Tactical Knife.
 * When playing online the USP .45 akimbo seems to have a faster knife than any handgun with Tactical Knife
