I actually convex the cutting edge by doing a 15dps to the apex, then put 18, 17 and 16dps facets. Then strop the facets into a convex cutting edge. Or some variant there of. I have yet to receive any Fiddleback that I would consider "scary sharp", either new but especially used. I can get any Fiddleback scary sharp using this method, and I have not learned nor perfected the mouse pad and sand paper technique. However, I have sharpened some Fiddlebacks to a V edge. If I am working with 01 steel, the most acute I will go is 16dps. I find that CPM 154 holds up well at 15dps. For the most part, Fiddlebacks come with more of a V edge than a convex one in that none are what I would call a 0 grind convex, albeit knowing Andy's process they are technically convex cutting edges. Personally, I find nothing wrong with V ground cutting edges, but I fully understand and appreciate the benefits of convex cutting edges for certain tasks.
But, bonafide is correct, none of this effects how the knife will fit into his excellent neck knife sheath prototype.:encouragement:
