Very interesting Cyrano and thank you! The story behind Sample B is this Grepper. It was a factory edge but we subjected it to further deburring with a Sharp Pad and took 150 points off the edge in the process so that at point "2" the measurement was 238 and at point "4" 235. Then we rolled a 1.5" section centered at point 2 (5) cycles and point 4 (1) cycle. With post roll readings being "2" = 598 and "4" = 487.
These are the best depictions of rolled edges we've seen and we're going to have to think a bit about what they mean. In some cases they seem to depict what we would expect and in others not. We'd really like to understand better just exactly what we are measuring with these rolled edges and it looks as if this photographic technique will help. These knives cost $4.87 each at Target Cyrano so please don't contemplate returning them to us.
