I am not a fan of either Shark Super Chrome or Super Stainless.Neither are sharp enough for my beard. However, I have found the new Shark Platinum blades to be pretty good. They are much sharper and smoother than the other two blades. Even the Platinum blades are not the sharpest blades available, but at least they are sharp enough where they should work for most folks. Thus, if you like Shark blades, I suggest you try the Shark Platinums.
