I just spent one hour posting my mini-review of several Russian-made blades. My login apparently timed out while I did this and when I logged in again, I lost the entire review. I love BB but I do not have another hour, so here are the results in the form of rankings:
Voskhod > Perma-Sharps and Ladas > Astra Super Plat > Sputnik (Teflon-coated) > Astra Super Stainless > Gillette Rubie
The Permas and Ladas could be considered equal to the Voskhods and I would not argue. Also, given the price of Gillette Rubies, I was sorely disappointed.
Sorry again about the review being lost.
