Was recently backpacking with a brand new Bday present - Fiskars X7. My older Fiskars is nearly a full convex but I decided (in the interest of time) to slowly convex the new one as I touched it up. In a year or three it'll be a full convex like its older brother who's chopping abilities are legendary in my circle. I did touch up the factory edge as these are notorious for weak/wire edges out of the box, but kept the factory V bevel and angles. I was impressed at how well it split American beech rounds - some nearly two ft long, and could still chop with ease as well. It occurred to me that if you knew in advance what the material characteristics were of what you were chopping, you could design the perfect V edge with shoulder corners and back bevel thickness maximized for wedging/chopping/slicing action etc. Convex gives a greater margin of error in most cases but still not a silver bullet - all depends on what you're working on, and if the back bevel is sufficiently thinned out the argument becomes a lot less clear. Love my convex but also love my FFGs and Scandis and ....
Edit to add:
I work in the graphic arts, the blades on our paper cutters are D2 with two flat bevels into the cutting edge - they last a looong time.
