i guess, as mentioned, I'm not sure what purpose this would serve. as mentioned, when would you "cut molecules"? Even if the guy was in a room with chlorine gas or something similar, are we now also supposed to believe he can see individual molecules, and cut them by the thousand in a fraction of a second? It is your world, as mentioned, but the more implausible you make it the harder the sell. In this case, other than your sense it would be "cool," I'm not sure there's a payoff....but it isn't my story and you would know more than I do.
