These blades are quite dull for my heavy beard. Even in the R41 they tug a lot. Significantly better in the Progress @5. This razor amazes me every week. There was a bit of tugging in the goatee area, especially the moustache was hard to shave, but still a decent shave. No cuts, no irritation. Not a BBS, but rather DFS+. If I remember correctly, these blades are getting perceivably sharper on shave 2. We'll see.
