It. Doesn’t. Work. That. Way.
You have only 2 hands. 1 is used to position the “sweet spot” of the enemy so you can’t miss it in the dark and maybe stab yourself instead (at least if you practice enough), and also provide backup pressure on that area so your strike’s impact all goes into penetration instead of just pushing the enemy away. The other is used to deliver the blow. This means you can’t control other parts of the target’s body. You can often control weapons slung on the enemy’s back or shoulder because you pin them between your chest and his back. But if he’s holding something in his hands, he’s going to drop it (KLANK!). And his legs are free to kick and thrash, which they ALWAYS do even if he’s clinically dead before he hits the ground. Heels drumming on a wooden floor even without kicking over any furniture, make LOTS of noise, as do feet thrashing the underbrush.,
If you go through the skull or ribcage, you have to penetrate bone that evolution specifically designed as armor for the important things beneath. There is no way to do that without hitting hard, and hitting hard enough to do the job unavoidably makes significant impact noise. There’s no way to muffle this. If you stab down through the base of the throat, that more often than not causes some sort of exhalation sound from the enemy (even just the “OOF” of sucker-punching somebody in the guts) , and then he’ll gurgle and blow bloody bubbles for a while (even once unconscious from lack of blood to the brain), and such noises can be QUITE loud as he’s full of adrenaline now and trying his best to scream even though no air can reach his vocal cords (if you did it right) and it’s all coming out the “tracheotomy” you just gave him.
