Edge Pro vs. convex edge

[Wildewinds]

So I've ordered my Edge Pro Apex and should receive in the next couple days. I've also got a Fallkniven on order with a convex edge.

Taking into account that I've never tried to sharpen a convex edge before and don't have a belt sander to do it that way, do you guys think I'd be better off using the Edge Pro to put a normal edge on the knife instead of sticking with the convex edge?

As long as it has roughly equal cross section and final angles, it shouldn't matter a whit. Find the final angle using the Edge Pro, sharpen at that, and then take the shoulder down using a lower angle... it won't actually be convex, but it shouldn't be much different.

Fallkniven uses a primary convex bevel but has a secondary flat ground edge bevel. But Bob makes the correct point in any case that it is more about the angles than flat vs convex.

So... there's nothing special about a convex edge that makes it worth my while to learn how to do if I have an Edge Pro?

I could be wrong but, I don't see an easy way to make a convex edge on the EdgePro, or any other jig type sharpening system, so you've pretty much got to emulate a convex curve with multiple straight sections. A true convex curve pretty much requires a free hand method. It should not make noticeably difference performance wise.

Pretty much yes, the major part of the performance will come from making the edge angles on the knife suit your tasks. The first thing you need to realize is that edge edge has pretty much two parts, the main bevel which shapes the edge and the final bevel on the very edge. For most knife uses (outside of really coarse twisting in hard materials) the primary edge bevel can be very low, 5-10 degrees. The secondary bevel is usually much more obtuse, 10-20 degrees depending on the steel and the tasks.
