Gillette 7 O'clock Sharp Edge (Russian made) in a head to head with the infamous Gillette Super Stainless "Spoiler" of circa 1978.
Loaded in two identical razors (1959 Gillette Tech) for a side by side trial run.........and the verdict is: I couldn't tell the difference between them in day 1 using Aqua di Parma shave cream.
Spoilers usually last between 5-6 shaves for me, I think this is where they'll win in the long run. I seriously doubt the Gillette Sharp Edge can get me there with comfort and safety.
I will post my final verdict in a few days.
