Gross stuff under the black.
Arms: Tourniquet them to stop the flow of blood for a while. Chop with big hatchet for dramatic effect. Use a bone saw if you want the slow pain.
Legs: Pretty much the same thing, but you'll want to tourniquet a little lower. There's big arteries that go through the inner thigh.
Eyes: A good deep sea fish hook sounds like it would to the trick. Once it's out of the socket just nip the stalk with some good kitchen shears.
Jaw: This is interesting. There's a lot of bone involved there. You could shatter the jawbone with a ball-peen hammer, then knife the bone out, or you could do it a little more gruesome, knife your way in from the lips to the back of the mouth to get your horizontal, run a vertical cut from jaw to jaw under the chin (careful to avoid the arteries. You don't want to slit his throat.), then once you have the bone and teeth exposed you break out the bolt cutters.
NOTE: H E A V Y sedation is involved. It's highly doubtful you could pull off this kind of thing if the person is awake. They'd likely die from the trauma of missing limbs, etc. The only way I could see someone getting away with someone staying awake through most of it is a spinal block (I think that's the right term for the big needle that goes in your back?)
Yes, to do all this some medical knowledge would be required.
Thinking about this a bit more....
I remember that liposuction is limited to a maximum of 10% body mass at a session. Anything more threatens shock and can cause death. The legs probably would have to be done piece by piece.
On the more grotesque end of things:
I wonder if you could get away with separating the artery from the thigh of the inner leg (while still keeping it intact) and tying off all the lose ends to prefent blood loss. Then severing the leg high up on the thigh...or would that cause a pooling of blood issue?
NOTE: Don't worry all. I just have a vivid imagination. No furbies were harmed in the making of these ideas. No kittens were killed either.
The most grotesque thing I've ever had to do involved a cat that was already dead when I found it...poor thing got trapped and started decomposing. I had that stink with me for a week. I'll never be rid of the smell. /shudder ...oh, and mice. I've killed mice humanely. Quick blow with a skillet.
epidural or spinal block yeah, and you would need a LOT of arterial clamps, and probably the most gruesome way to do it would be to cauterise the wound to stop them throwing fatty embolisms
alright so...
Apply the tourniquet high on the leg, cleanly saw off the leg about 3 inches below the tourniquet then take the flaming hot bottom of a frying pan and sear the stump closed. Remove tourniquet. Pan fry thigh pieces and serve to victim. Maybe like "on the ham-bone" ring style?...similar to the Silence of the Lambs 2/3? brain thing.
I can see it on the shelves now:
Thread of death!
Oh, that's a thought....dismemberment by garrote thread.....you know, the one they use to cut down small trees with?
