Actually, a member of the forum PMed me yesterday and made me present that Rapira blades have uneven edges. And it's true... I think quality control is a real problem in Rapira factory. So, i am rather happy that i have 300 of the rapira factory and 4950 from other factories. My only other Russian blade, is 1200 Astra SP. And i don't worry about them.
This is an unused Voskhod that i bought from a reputable italian shop:
As you can see, 1) there is a slight difference in the edge width and 2) the Rapira logo isn't fully printed.
The blades i received today (from Russian), have the Rapira logo fully printed, but they also have uneven edges, maybe even slightly more so. And i unwrapped a Rapira SS and the uneven edges are even more prominent than in the Voskhod. Also, the wax wrapper of one of the russian delivered Voskhods has a wrinkle and one edge is uneven, like it was sort of torn. Hey, but the logo is fully printed this time!
I don't know what's going on, but i have used 2 Voskhods from the italian tuck and it was the smoothest gliding blade WTG that i have used. Which is why i decided to make the "final push" and get 300 more from Russia. I suspect that there will be many duds, because all of this means poor attention to QC.
There are theories, that 1) Fake rapiras exist, 2) Ebayers sell Rapiras that didn't pass QC, 3) Factory has poor QC and blades come out with uneven edges.
I am more inclined to believe #3, but after i will have shaved with the new ones and compared them with the "italian tuck", i will be more certain. Thing is, bought locally, i would have paid about 57 EUR. Now i paid 22 EUR. Even if all are duds, i can live with that.
