These blades gave me three BBS shaves with no nicks, cuts or irritation.
The fourth shave was ok for work but not as close as the other three.
I think they might have gone five shaves but it would have left razor burn or some sort of irritation.
I put them ahead of Merkur blades as they seem to be sharper and smoother on my skin.
Definitely better than Wilkinson Sword.
As usual YMMV.
