Belstain,
I always ask my customers to leave a 1/64 flat on the edge of knives they send to me for heat treating. Since you are using a convex grind though, I would say you could finish that down to almost sharp, as your edge won't get to thin and burn off during the soak. If you need further information on my heat treating, you can contact me at the following email...... bearoates@aol.com
Hope this helps, Bearclaw
