I have a course beard, but I would guess this applies across the board for all beard types. That said, this is completely anecdotal.
I've been finding that blade edges that chip as they degrade cause less irritation than blade edges that roll. The type of steel, the steel's hardness, the edge angle, thickness, and any coating affects how the blade degrades.
Looking at the blades under magnification after using them I am finding that the more chipped blades start tugging before they start nicking and scraping. The rolled edges seem to cause more nicks and irritate my skin more -- I assume as a result of the rolled edges scraping my skin. It makes sense that the rolled edges nick more, because I'm using the angle the blade should be at, but the rolled portion is at a different angle and thus the roll nicks me or scrapes me.
I would guess the chipped edge blades also scrape my skin, but it seems less so far.
I'd like to see a hardness rating on blades to help choose blades. Maybe I'm getting too scientific about it though considering they're like 10 cents a blade.
Anyone else notice this to be true for them though?
