I have been comparing them for a while to decide which one to buy in bulk. I have liked them both, both blades give me a full BBS. I have been using them in a FaTip Piccollo with Proraso Green. This is what I have experienced:
Feather pros:
- Very sharp.
- Lasts for 10+ shaves.
- No irritations, redness or razorburns (even people claim this I did not experience it).
- Despite a lot of people avoid them and spread horror stories about it, I couldn't believe it at all. This razor gets blaimed for something it isn't. So I find this blade pretty forgiving.
Feather cons:
- Expensive compared to PermaSharp.
- Can be a little bit rough.
Permasharp pros:
- Very sharp.
- Super smooth.
- Lasts for 8 shaves.
- No irritations, redness or razorburns.
- Cheaper compared to Feather.
- BBS with two passes.
Permasharp cons:
- None.
Just in case anyone wondered from where I'll get my PermaSharps this is the cheapest store I could find:
