I've been using Astra Superior Platinums for what seems like two years now.
I tried a Feather blade once, about two years ago from memory. I must've pushed down while I was shaving. I had a delayed reaction of raw pain all over my face after the shave. I had to put an after shave balm on to help relieve the pain.
Now I have more experience with shaving I'm wondering if I should try a Feather again. If I do I'll leave it for a couple of weeks as I have exams starting next week. I do remember the blade I tried seemed to cut through my beard very smoothly.
The last time I used my Merkur HD but if I do try it again I'll put it in my Merkur Progress and make sure it's dialled down for a less aggressive shave. As I was newbie when I last tried a Feather I'm hoping the years of experience together with my face being more used to DE shaving will make for a more successful attempt should I go ahead with another Feather blade.
