You can see the heft a blade meant for a single head has in this video from guys who made one this summer: https://www.youtube.com/shorts/RPO7fm_ZtlY (it's a short no long video)

Perhaps the design could be altered.

I know the appeal of a guillotine is that it's fairly simple, but if we're gonna scale it up for maximal decapitating efficiency, then I feel like we can afford to have a motor with some horsepower lift the blade. Maybe two to make keeping both sides of the blade even easier.

We'll of we're just going for efficiency, what don't we just use a bolt gun?

I think the appeal of a guillotine is more... the vivid images of the French revolution it conjure.

We could still go for the massive one, just got to have some ratchet system so it doesn't fall before we want it to.
