I'd be fine with 1 hit kill with knife under the following conditions:

-Equip knife, like the current PS knife
-Secondary (noisy) mode must be on
-Must attack from behind
-Animation of kill (it's badass for the killer, makes the victim go "ah F$#%", and keeps the assassin from running up behind a group of players and waving his knife around wildly getting massive kills).

Attacks from anywhere but the rear (lol) would count as failed attacks. They'd do large damage (80% health?), but the attacker would be 'stunned', as if they had swung a sword (or any other similar object) at a solid, unmoving object such as a boulder.

Edit: During the animation I think the cloaker should remain semi-cloaked, like sprinting-across-the-battlefield-cloaked.

You could still get kills from the front, but you'd have to avoid being shot and the person would likely have to already of taken some damage.
