the Voskhod blades I received were kind of dull like Dorcos
This is mostly personal experience: the Voskhod blades I received were kind of dull like Dorcos, but slicker, and strangely forgiving.  Even after two passes, I wasn't smooth with these blades, but I could back stroke without bleeding.  As with any safety razor blade, try a five back before you go all in with a cart.
