Here comes some critical thinking from me:

1) Lemme ask you this, what are the usual stuffs that you can find in an operating room? Operating knifes for cutting people open? Yup, Law's nodachi is use for that. And notice the super lengthy blades (I'm still in awe over it! @_@), its for covering a wider area to slice up people inside of his room. What other tools? X-ray machine? Yup Law has those abilities too, remember he scanned people for the Den Den Mushi? Legit, yeah? With these facts, I deduced that Law's abilities revolves around what one can do inside an operating room. I won't be surprised if he can be doing something with the blood of the people within his room (kinda referencing blood transfusion process) or even sends a shock of electricity (referencing to the machine doctors use when patient's heart stopped, shocking the heart back to beating) or maybe he can hear the heartbeat and knows if his opponent is scared of him or otherwise (reference on stethoscope). The last one (hearing heartbeat) kinda similar to an opponent in Rurouni Kenshin who self-proclaiming has the "Heart-Eye" ability

2) We know Law has operated on Luffy two years ago. The question is whether Law extracted something to leverage (not the "you owe me" kinda gratitude, but something physically obtainable) against Luffy if they were to face off (which will be sooner or later). Many speculated that Law may have took Luffy's heart without him knowing. I see a critical flaw in this theory, remember how Gear Second works? Yes, pumping blood at a rapid rate to where? Yes, the heart! Luffy was shown to spam Gear Second quite a lot post TS, so this is the flaw to the theory. If Luffy does not have his heart in his body, how could he activated Gear Second (post TS)? Am I making sense?

3) Did you all remember in what state was the Head when it was first introduced? Yeah, scattered like some sort of puzzle blocks. Then do you remember in what state was the Head when it was dissected by Law from his body and brought into the prisoner room? Yes, still in one piece (no pun intended). This means as Law carries the head into the building, he must have been pissed off by the Samurai's attitude, well pissed enough for Law to further cut him up to release his frustration. Or alternatively Law could just be in the mood and cheekily played a joke on the head by further cutting it up before throwing it into the room (no pun here). I would buy the earlier scenario, seeing how annoying the Samurai's mouth can be... ;-)

4) Neo mentioned that the vic(tim) could reassemble themself back given the body parts were completely in place. Now this is an interesting theory! Lets consider what we have seen. Leggy attached itself to a dragon but could later be removed like being glued onto suggests that the sliced part does not permanently attached to anything. But then when we talk about the head just now it was in pieces which Team Shitty Nami (sorry Nami, I can't bear to face Neo's wrath!) reassembles back into one piece (again no pun intended). From the scenario of the head, it seems that the sliced parts could be permanently attached. So there's a contradiction here. I can foresee some may say that only with its own body parts will it stick up permanently, then we last see the samurai having its head on top of his bottom (half), so was this a permanent effect (bypassing the torso)? A very interesting theory here indeed.
