Hi all! I've been using Feather blades since I started DE shaving a couple months ago. I can only get 2 comfortable shaves per blade - 1 WTG pass and 1 ATG pass. Is there anything that matches the sharpness of the Feather with better longevity? I've experimented with Derby blades which work quite well. I can get three comfortable shaves with these but they're not as sharp as I'd like. I also tried Personna Platinums which felt quite harsh.
