The guys and gal below are right on with their comments. Voskhods start out "super smooth and just sharp enough" and then they hold that performance way beyond most of the others. The fully Teflon coated carbon steel material (not SS) used seems to be a game changer. I have been checking; but, have not noticed any rust issues what so ever. No special blade care taken either. Nicely double wrapped and no glue spots (awesome, pet peeve of mine). A fine pairing for any aggressive/efficient razor, IMHO. Might not be sharp enough for some folks in notably mild razors.
1st class comfort on DFS/BBS shaves, more shaves per blade and one of the lowest price points too. What else does it need? Highly recommended, I'll be getting 100 on the next order to IB. Great job IB bringing so many several special products to market. I would have missed out on so much without you.
