Recently, I tried Voskhod blades in a test with other blades. I used a UK Aristocrat razor with a number of different blades including the Voskhod. With that razor and a Mergress I could only get up to three smooth shaves with those two razors.
I went on a trip and brought along a Karve razor. I had been using that razor with a Voskhod while at home and used that blade for three shaves. I kept the same blade in the razor on the trip and got a total of 7 shaves with that combo. I decided to put in another Voskhod blade in the Karve. Another 7 shaves.
The lesson I learned: try a blade in a different razor. It may make a difference.
