After sending astronauts to space, the US realized their guillotines were useless. This was the 1960s—the height of the space race—so NASA spent an absurd amount of money to develop a guillotine that works in zero gravity. Rumored to cost at least $1 million (about $9 million in today’s dollars), the “space guillotine” can behead upside down, at extreme temperatures, and even underwater. This feat of American inventiveness allowed astronauts to be beheaded in space.
Faced with a similar problem, the Russians used a machete.
Magnets. Would serve as a useful upgrade here on earth, while making the guillotine space-compatible too.
We send guillotine blades in a stable orbit around the sun. The suns gravity and the vacuum of space will ensure that a decent speed will be kept for the next few million years.
Billionaires get disposed off by sending them into that orbit. Should't take too long.
Let's make out star system a guillotine!
Simply take away their space suit and expose them to the elements.
Let the universe take its natural course.
That was my first though, shove them out the nearest airlock.
You could push the blade by releasing pressurized gas into the vacuum which is how rockets sometimes adjust themselves in flight.
Strap some ullage motors to that badboy and there's your "gravity"
