Can someone do the math on this? What kind of force would you need on the blade to cut through 15 fat rich person necks? How heavy would it need to be? And what speed, like how high would the drop need to be? Would it be strong enough to just hold at two ends, or would the flex cause issues with it not dropping straight?

At this point it would probably be better to have some kind of pneumatic cylinder that chops off a single head, but does it really really fast. That way you can just drop down the rich asshole, lop off their head, pull the body away and plop down the next one. How much throughput could we get with that?
