I'm happy to hear you are enjoying your WSKO. But this whole convex with with the worksharp is a myth. Yes, it convexes the edge some. So does freehand sharpening. It doesn't matter. You can still sharpen your "convex" edge on a flat stone or sharpmaker, or pretty much anything else.
A real convex edge that is continuous from very high up on the blade all the way to the edge is rare and is generally regarded as being special in some way. Thus it is worth preserving and it's worthy of extra care to keep it that way. Japanese swords are one example. I'm told that Bark River's knives are like this as well.
But the teeny tiny little convex edge you create with the WS (or WSKO) is so small it affects nothing. You can easily flatten it out again, or just touch it up with nearly any sharpening system and it will still work great.
It's really too bad that the marketing literature and the Internet refer to the WS edges as convex because it really is the equivalent of a myth. It just doesn't matter.
