I have shaved with some of the Soviet made blades back in the days. Even the Stainless steel ones that were made for shaving were pretty bad. The carbons like Нева (Neva) were terrible, even though they were made for shaving. Still have a couple of 80s Voskhods, but don't want to shave with them. Nowhere near the modern production of MOSTOCHLEGMASH.That’s what my research led me to believe as well - I read something about sowing which exactly what will happen after I would have had a shave with them! I still like the vintage aspect of them though.
