I find these to be the roughest of the 4 Moscow blades I've tried (Plat Lux, Swedish Super Steel, Voskhod and this one) but perhaps it's a bit sharper than the Plat Lux and Voskhod. They are definitely the cheapest and most commonly available. I toss these after 2.
I've been using the Rapira Platinum Lux this week, and on the 4th shave, it's still working great. As far as price, I can get either the SS or the Platinum for the cost. Haven't tried the SS yet, but with what I am reading, I might skip it now.
The other Rapira Stainless in the 2 color package are an excellent blade as far as I find. I'm sure these 2 are not so far apart from each other. Like any other blade, go easy on the first shave then it's excellently smooth for another couple or 3.
