That's exactly what I would like to hear - how do they feel/cut/glide/etc. different...
I think there is a lot of myth out there about carbon vs. stainless and it would be great to hear from an expert the actual differences.
I think there is no easy answer to this as most of the feeling and "touch" of every single steel - I would say, every razor - is different one to each other and to each one of us.
I am not an expert, of course, although it is now about 16 years I am shaving with straight razors and probably used more than 800 different straight razors, I certainly am far less than a beginner when compared to a revered expert like Mastro Livi.
It is said carbon steel is "rounder and softer" than stainless steel, but I can tell there are stainless steel blades equally round and soft like a carbon steel. I guess steel composition has a role in this as well as how it was processed and worked.
I can however tell there are steels which actually feel more aggressive than others on the skin and this does not necessarily mean it is stainless steel.
As for cutting and gliding efficiency, my very humble experience tells me quality of honing, grinding and geometry is everything. Like Mastro Livi said in the second part of the School, the edge - in order to give a comfortable shave - has to be very very thin, with a height of half a millimeter or ever less. I can witness this to be absolutely true, no matter it is a carbon or stainless steel blade. As for efficiency of cutting and gliding, stropping certainly is an essential part of the shaving experience and, in my opinion, hand palm stropping adds an extra special touch to shaving. I can personally tell when a razor was not hand stropped: I simply feel the difference on the skin.
