Well Voskhod is the first time I can say I've noticed a blade perform differently from razor to razor. It really was awful in the iKon OC, but it was fine in the DE89.
I'm finding some mixed results with 7 o'clock Yellows and Nacets. I'm even wondering if this is the same blade - same factory. They're both clearly sharp and can give a rough first shave in a more efficient razor if you use too much pressure. Both seem to bring milder razors back to life. They both seem to get a little smoother after the first shave as well.
Voskhod's are my go to blade however bought 50 GSB and the Gillette is definitely sharper. Would put it almost on a par with a feather but much smoother. Voskhod's just don't have the same level of sharpness to be the same blade but as always YMMV.I keep wondering if Gillette Silver Blue and Voskhod are the same blade. Not 100% sure but damn it's close.
Maybe all of the blades coming out of PPI have both a global (Gillette) brand and domestic (Russian sounding) brand version - it would make good business sense, surely?
First three no issues...no 4? Have no clue...Personna Reds (Israel) - not sharp enough
Astra SPs - random blade life
Gillette Rubies - tuggy
Lord Platinum - tuggy
It quiet funny that I actually like the Treet carbon blades
YMMV as usual
I bought 100 Voskhods off ebay seller unuta77. I have had these blades from different vendors in the past and loved them but these are rough on the first shave and completely unusable for a second.
Wouldn't discount the Voskhods but would advise staying away from this seller.
