I got a very large assortment of blades for Christmas, and I'm working thru them.
At the moment I have 2 piles, maybe, and **** no.
**** no gets assigned to blades that make me reach for moisturizer at the end of the shave. I suspect small burrs on the blade that disrupt the outer skin.
Gillette 7 O'clock sharp (green), Bolzano, and Derby extra are in that group.
In the maybe pile, Lord Platinum, Wilkinson Sword, and Gillette Platinum give good shaves with no irritation. I tried a Feather stainless, and it didn't have the burrs, but my face was mildly irritated. It's still in the maybe pile, I may just need to turn the adjustment from 5 to 4 1/2 on the razor.
