Hi Clay,

Fascinating pictures! I'm curious, how did you "super polish" the edge to begin with? :)

Clay,

I have been meaning to ask, 1.) what steel is this that you were using for these tests, and 2.) what RC? Just curious ... thanks

I progressed through the usual diamond plates, then on to the Micro-Fine ceramics and then used 1um diamond on cow leather, .5um diamond on cow leather, .25um diamond on kangaroo and then .125 CBN on kangaroo. I didn't spend so much time as to remove every last scratch, just the vast majority.

I've been using a bunch of utility blades from the same 100 pc pack so that they are very similar. They're listed as "high carbon" though I don't know exactly what the composition or hardness is. If I had to guess, I'd put the hardness around 57-58 HRC.

So you did ship the Super fine 1200/1600 in this case? Did it take you much longer with the next ceramics since you did skip the fist?

In this case I did skip them and it took a little longer, but not too bad, partly because my diamond plates are so well worn in now that they're already doing a lot of polishing before I even get to the ceramics.
