sharpening angle for m18

[jbarrick24]

Which angle do you guys use to sharpen the m18? I am using a smith sharpening system with an angle selector, 25 and 20 deg. I have used both angles and can get it fairly sharp, but not shave your arm hair sharp.

Try your 20 deg. slot and when you've got your best edge, try this. take offf your leather belt, tie it around a doorknob, and pull it tight and pull your blade backwards on the belt. Try to use all the cutting edge when doing this. Try 20 stroks alternating on each. When done try your edge on some paper. If better, repete. It will all come together with practice.
