Would it be possible to stack multiple double-edge blades into a shaver head, slightly offset to each other, to perform like a traditional multi-blade disposable razor?
Or is the thinness of a disposable blade what makes it work well, assuming the blades can flex more to follow the skin profile?
I could see a product where you install 3-4 double edge blades into a the shaver head, and then "flip" the head or blades once the first side runs dull.
