If you could do a test on Mühle blades I’d be most happy.
Based on the packaging, these are the most aggressive blades ever made. Can you get hold of some to test?

Thanks for the tests. I have been thinking about a similar test myself, but never got to do something.
One thing is bothering me with the results. I have difficulties to accept a blade is getting sharper by shaving. Could it be that your test media is easier cut by a destroyed edge? From microscopic images of the edge I have seen a clear change in appearance, a used edge is less straight. It resembles more a saw with really small “teeth”
I say this because with some of the blades you claim get sharper from a shave, I clearly experience more tugging when used a second or a third time.
How about testing with some wool? Wool is after all hair…
Hi Engblom, thanks for the comment. The test media I use is a consistent clip that is purchased from a sharpness testing company that uses a consistent string. Using wool I do not feel this variable would be as controlled.
Regarding your comment about the edge being destroyed, I do not think this is the case. Check out this link from Mantic.
This is for the Crystal blade, you can see the unused edge has a very thick coating. If you look at the edge after it is used, the edge does not appear to be damaged or have any saw like teeth. These images that Mantic was able to publish are using an SEM microscope and impressively high quality.
Due to this I suggest the initial coating covers the sharp edge resulting in a lower reading, and as the coating is worn away it exposes the sharp edge for a sharper reading. I have also had lots of feedback from people confirming they often feel like the second shave is sharper than the first for many blades.
Nice to see would be Super Max range of blades from India. The Super Max Super Platinum is quite loved and popular. Recently a new blade Diamond Edge has been released and getting good reviews. The Super Max stainless to me is not smooth but would be worthy of testing.
Also the grey box packed Rockwell blade to see if its just a cosmetic change in packing or of the blades have been upgraded!
