I took some weapons-based martial arts, and a general rule of thumb for bladed weapons is; the more of the blade you use, the more cutting it does.
If you're using a sword to try and cut someone's head off, if the only part of the blade you use is a little length only as much as the neck's width, you're gonna have to put some serious muscle behind it.
What the black-belts teach is that you should start with one end of the blade against the neck, then drag across to the other end, same cut with a fraction of the effort.
If this guy's guillotine had a 10' blade with an even sharper angle, it'd be able to cut off a head with even less weight pushing down on it, but then it'd prolly need to be a 30' tall structure.
