So this is what i'm thinking. With wet shaving proper those of us that only ever knew of the fixed angle of blades locked in to in cartridge had to re learn how to shave understanding the angle to come in at to get your bbs. And with every tool be it agressive or mild de,se or strainght they all have their own learning curve and everyones face having its own terrain you end up with own best angel. So there blades are locked in at a fixed angel like the cartridge style. And the blade they'll be using will be sharp as fook. So my prediction is with the science of hysteresis applied to the first blade pulling the hair up and the second cutting deeper and the third cutting even deeper you'll be loosing a fair bit of skin per shave, cos you'll have to press harder to get that close shave. And what do we know about pressing a de hard to ones skin? Yep razor burn like hell fire and bleeders and weepers and blood loads of blood lolI'm not sure what it adds?
Will it reduce the number of passes - probably not as people will still want to go WTG, XTG and maybe ATG based on preference
Will it be smoother - probably not as @Holyzeus has said, the first blade will probably remove most of the lather
On the plus side, it allows for three levels of aggressiveness in one razor, but that's not much different from an adjustable.
It actually becomes more expensive to run than a normal DE or SE or even a half blade SE such as the Rocnel.
I'm intrigued. I'd like to know how it performs, but I'm a little sceptical as to what the benefits will be. I'm all for innovation though and would be happy to be shown otherwise however.
