What blade do you use with your Feather? I have only tried a Feather and Personna Lab. The razor is definitely more efficient with the Feather, but it irritates my skin the first shave or 2. I don't get any irritation with the Personna, but the razor isn't as efficient. What are some other sharp blades that might work?
All blades are sharp. That's why we buy 'em and use 'em. Everyone likes something different. What works for me may tear your face up. Best to get a sample pack and ask your face what it likes.
I have found the Gillette 7 o'clock black and yellow to be similar to the Feather but less harsh. Again everybody is different.
