I had my first shave with my 1920s Valet razor and a new Valet Feather blade. I couldn’t believe I had only one minor weeper. There was a lot of drag and definitely not a smooth shave. I will try using it for final touchup.
Feather FHS blades are a step above box cutters. I don't find them efficient at all. If you have an early Valet that can use despined GEM SS PTFE blades, the difference is night and day, GEM blades are much better.
