S390 polished edge retention testing Kknives_switzerland. Will S390 pick up with a polished edge? Or will it loose performance? This is the S390 protocol Roman uses in his knives compared to the failed experiment 66 hrc S390. First S390 was run on a 1000 grit SiC King K80 finish then a high polish down to .3 micron diamond film with a .5 micron strop. Below are links to Roman's Instagram and the previous test of S390 wirh a coarse edge.
