Regarding the long primary grind on the swedish rapiras; I notice my all my rapiras have the same grind except the "ladas" blades I own have the longer grind your swedish rapiras have. I don't know what significance that has though.

Has anyone done followup work to this great post? Also, do we know of anyone with access to the sharpness measuring instruments alluded to in this thread?
I just started watching the forum and wet shaving about 2 months ago and just discovered this thread. Wow. Great job. I love the data and the objective look at the blades I am hearing so much about. I just happened to be using Personna blades. They come in the blue box in a lot of 100. I hope they are represented in some of the Personna tests here. Its hard to tell since mine don't say "blue" or "red" or "lab" on the box. thanks again for the work

The blue box are why they are called blue's, the red's come in a red box.
I love the pics and am wondering if the roughness of a blade is due, in some part, to the striations.
What say you?
Do the coatings "smooth out" the rough striations?

Where are the pics? All I see are Photobucket error messages . . . ?
Try again now, they're working again for me.
Exactly. Microscopic viewing won't as well tell you anything about the "golden" ingredient in the mix: the sputtering.

Good Lord, the Feather looks like my bread knife.
Great pictures.
Several observations.
1.No iridium in Polsilver coating.
2.Gillette seven o’clock stainless, the edge looks very jagged.
3.Lord blades are extremely contaminated during manufacturing.
4. Personna lab looks better compared to med prep

I don't know if anyone asked this but is there a way to view them from the side? To compare how sharp they are or see the angles to the edge? I love this stuff. Its fascinating.
I'm trying to understand what the measurements referring to , now I forgot proper nomenclature, but not referring to the apex, what does that matter? Isn't it the very tip or apex that matters? Very cool, I love this kind of thing.
