I decided to start with the Treet Carbon Steel blade because I've never tried a modern blade that wasn't stainless.
This blade was tested in a Ball End Tech, with Nivea Men Sensitive Shave Cream (one of my favourites) applied with an Omega 11574 boar brush.
On the first day, Treet Carbon Steel blades gave a satisfactory 3-pass CCS shave,with more blade feel than I'm used to. There was minimal post-shave irritation, the tiniest tingle from my alum block. I had tried a Treet Platinum Super Stainless in the past and found it quite satisfactory, giving me a 3-pass DFS. The carbon steel isn't in the same class.
Second day, it was more of the same, maybe a little rougher with a little more irritation.
So I decided to push my luck and try for a third day. That was a mistake. The shave was SAS, looked OK, but with enough hidden stubble to make my neck feel like 120 grit sandpaper. The alum block definitely made itself known. In retrospect, I should have quit after day 2.
I'm a little disappointed in them. Rewinding my memory 55-60 years, I seem to remember that the big advantage that CS knife blades had over SS was that the CS was capable of a sharper edge than SS. It wouldn't hold that edge for as long as the SS, and it would corrode, but it could be sharper to start. That doesn't seem to be the case here.
Sharpness 6/10
Smoothness 4/10
Overall 5/10
