Advantages of a convex grind???

[Gossman Knives]

Correct me if I'm wrong, but I think these terms are a little confused. You can have a hollow ground knife with a convex edge. The convex portion of the blade is only the edge, not the entire blade.

Yes, that's true. You can convex the edge on any grind.

The Sebenza comes with a deep hollow grind and a convex edge. But you can also have a blade with a full convex grind from the back to the edge.
