[Suggestion] Stealth knife execution

If you can stealth up to a animal with your knife, you should be able to do some kind of stealth execution for heavy damage. Using a knife to hunt deer, etc is pretty impossible. A stealth headshot thrown knife will not kill them. A stealth melee will not kill them. So you are forced to either have to use a bow & arrow, or constantly try to chase them down. If I can manage to stealth up to the animal, I should be rewarded for my efforts.
