You hear this many times on the forum when somebody says I just got a razor that was "Supposedly" shave ready but it won't shave..
Usually one of the Mentors or Senior Member's will ask about the stropping and mention "Folding the edge" this is usually hidden by tons of posts with tons of opinions and tons of fixes having nothing to do with the issue :(
I just got in two Dovo's that were honed by two different vendors, both of which under Magnification tell the same story
I tried to capture what I saw with my USB but it was clear as day under the 65x loupe
These are Folded edges, these will not shave, this has nothing to do with the original honing, this is all about the subsequent stropping, this is what the experienced members mean when they say "You might have folded the edge" ...
Depending on the severity, this can sometimes be Stropped out, obviously these two need re-honing however...
