M9

"The default combat knife. Necessary for close combat, it can be used to silently elimate an enemy."

- The Arsenal

The M9 Knife is the default Melee item given to all players at the start of their career.This knife does modest damage for its quick double-slice primary attack. When Nexon patched the game up and added secondary melee attacks, players gained the ability to stab enemies. The M9 is the only knife which leaves your hand when you stab. You throw it into the air briefly, catch it, then stab (basically a showy flip). If you don't plan on playing any Melee-Only matches, it is recommended to just stick with this weapon, as it's free and it has a fast attack rate. Its left-click attack (double slash) does less damage than the right-click attack (stab) but it is quicker to perform. As of the 3-31-10 patch, new permanent cosmetic variants of the M9 with slight changes in overall preformance (draw speed, attack speed, etc.) have been added to the game. These variants require a certain rank to be distributed to one's Inbox. The variants are the M9 Professional available at Master Sergeant/I, M9 Veteran available at First Lieutenant/I, M9 Elite available at Major/IV, and M9 Champion available at Lieutenant General. Players must be careful when knifing because if they're too good, hackusations based on well-aimed headshots may cause a suspension.

Trivia

 * The M9 is used for many glitches such as going through walls and falling out of the map.
 * Being the second lightest melee weapon in the game with the first being the M11 Tactical Knife, players often hold onto the weapon while sprinting to get to places faster especially if he/she has already used up his/her grenade(s).
 * The M9's right-click attack just looks like a lunge in third person as it does not show the person flipping it and using the overhand stab attack.
 * The M9's left click attack in 3rd person view look like your attacking downwards, but from your view is attacking from side to side.
 * Most used knife in the whole game because it is easily obtained.
