lol sorry I missed that. yea not a special but as far as I know its the only instant kill melee upgrade. hunters seam to have the worst melee upgrades from what I can tell. blink strike is all but useless, warlocks normal melee is a longer range strike then it. throwing knives are great, love em specially with 2 and juggling, but not all that useful. takes more the on to kill by witch time you are likely dead. though they are great to use in a gunfight when your gun runs out and you already damaged someone.
