I tried an angle of 18 per side all the way to 3.5 strops then went back to 20 and gave a micro bevel of 10 strokes with my 1600 ceramics. Then back to 18. For 5 strokes with cow leather at 5 um. For my whitetail it was like sliding through butter very slick. I was using a blackjack with d2 tool steel.
