Why are cartridge razors so much easier to shave with. This is the case for me at least. I'm assuming that the blades angle on the cartridges are just right for no matter which way you are shaving? They've dumbed up the process so you can't screw it up? What gives? All I know is that I get close irritation free shaves and no cuts with a cartridge yet I'm still learning DE after some time now. Just seems easier for me.
