I just finished the 5th shave on the first Red out of the tuck I have, and it's definitely a smooth blade, with decent sharpness. Not quite Pol-Silver, Feather, or even perhaps a bit less sharp than an Astra SP, but really smooth. I've been using one in my Rockwell, and plan to try one in my Slim next, which up until now the best or smoothest shave has been using a KAI blade.
