I'll compare this to a PolSilver, which was my prior blade (and I believe I used it for more than 7 shaves, I lose track). The initial shave was slightly less smooth as a PolSilver, but it seems to be equally as sharp. My second shave, which was this morning, with a great lather of Tabac with Proraso Pre-Shave, was incredibly smooth and sharp enough. Three passes, and barely any sting from the post-shave alum.
Let's see how many shaves these last, but so far so good. I'm loving most of the Russian blades
