Published: 4 years ago
This is the first of the test blades from Roman, Kknives Switzerland run with a coarse edge. 68 hrc S390, 66 hrc S390 which is a failed experiment and 62 hrc M390. These will also be run with a polished edge to see which works better. The 2 S390 will be compared and the 62 hrc M390 compared to the best M390 so far the Spyderco PM2 62 hrc.
