FEATHER Stainless VS. Carbon DE Blade. Which one is sharper?

Hi,

I'm currently shaving with this FEATHER DE blade which I load it into my shavette and shave every morning:



As I was looking on their website I found that they have carbon DE blades as well:

Can someone please tell me the difference between the two? Which one is sharper and will give me a closer shave?

Well, things may have changed over the years with advancements in metallurgy but it used to be that you could put a sharper edge on carbon steel but it won't hold that edge as long. It's why, as I understand it,  knives made for professional chefs have always been carbon because sharpness is what matters most to them and sets made for average home use were stainless  because convenience is more important.

Generally carbon holds the best edge, but, as all medical equipment is SS, manufacturers have become quite adept a producing sharp stainless blades. I've never seen the carbon blades in the field and most would say Feather SS blades are plenty sharp.

IME carbon Feathers aren't nearly as smooth/refined as SS.
