Hi there Mike
I have found the whole blade thing to be rather weird sometimes. Some blades feel uncomfortable during the first shave, then get better on the second. Some blades work great in one DE but not so nice in another. Cetain blades work differently with different shave soap. Some people will say that blade X is brilliant and others will say that the same blade is not so good.
I have also learned that some blades edge is a different angle to other blades, so if it feels rough at first one has to adjust the angle of the DE on your face to get a better result.
Nevertheless, I am loving the journey and experimenting with different blades.
