Just reprofiled the blade to 18 degree(green mark) on Apex. I guess it's per side, 36 included both sides. Finished with 600 grit stone and tape polished. Made it so sharp that when tried to shave the hair were popping up, like jumping goats. Then put a secondary edge on fine spyderco roads at 40 degree included both sides, about 20-25 strokes per side. Then leather stroped it for a couple of minutes. Tell you what,now it's the sharpiest knife I ever handled . Let's see how it will hold it's edge over a couple of days, hope better than before.
