I love those pictures @Theleme! You can see that the edge gets smoother the longer you shave with it.
I hit 90 today with the Nacet. I'm starting to suspect something. It seems that when I flip, as I do at irregular intervals, it takes a day or two for the blade to cut well again. The difference is subtle so it may just be other factors.
I'm still impressed with the quality of the shave, but I have to work at it. ATG is pretty difficult. I'm committed to two more shaves as that will be the end of the third month. We'll see after that.
The biggest, absolute thing that's happening here is that you are "learning" from this run and you can use what you learn to "improve" your technique, and that's what matters most!
You clearly see what a blade is capable of, and that's what Excalibur is all about!
