Not only do you have the heaver blade (the cleaver), that in its sheer mass make moving the razor across the stubble easier... but you have a lot more steel behind the cutting edge. This strengthens the edge so it last longer and cuts more consistantly( thats why once you get a straight sharp you only have to strop it, while actual sharpening is needed once or twice a year).
The safety razor blade will have a very thin (low mass) body and there fore cannot move across the face as smoothly even with the added weight of the razor. Its bound to "vibrate" even if on a micro-level causing a "hit and miss" type of cutting action.. kind of like when you drag a squeege across a window at a steep angle.. you get a rapid skipping action as opposed to a clean sweep so to speak.
