Hi Polarbare,
Your first time working on a convex edge and getting it hair cutt'n sharp is something to celebrate! Honing is a skill that takes time and practice. The more you do it the better you will be. I'm a real beginner at convex edges. Some of my experience with stone honing transfers, but the skill is different enough that it's a new learning experience. For your slimmer blade knives you may want to check out using honing stones. I think that convex edges are much better suited to thicker blades. ENJOY!
